• Harm (such as harmful tampering, data loss or alteration,
regardless of motive or intent)
Be aware that there may be a risk of unauthorized intrusions
associated with your system and/or its networked equipment. Also
realize that, if such an intrusion should occur, it could result in a

human/data privacy, intellectual property, material assets, financial
resources, labor costs, and/or legal costs).

Overview of Voice over IP (VoIP)
Introduction

Overview of Voice over IP (VoIP)
Introduction
This chapter describes the differences between data and voice networks, and the factors that influence the
performance of VoIP. The installation and administration of 4600 Series IP Telephones on Avaya media
servers, and the installation and configuration of DHCP and TFTP are addressed.
Overview of Voice over IP
The 4600 Series IP Telephones allow enterprises to use Voice over IP (that is, packet-switched networks)
instead of telephony over the Public Switched Telephone Network (PSTN). However, the use of data
networks for transmitting voice packets poses the problem that data networks were not designed for the
specific qualities required by voice traffic.
Data and Voice Network Similarities
Data and voice networks share similar functions due to the nature of networking.
• Signaling is used to establish a connection between two endpoints.
In a voice network, signaling helps identify who the calling party is trying to call and
where the called party is on the network. Traditional telephony uses terminals with fixed
addresses and establishes a fixed connection for the communication session between two
such terminals, allocating fixed bandwidth resources for the duration of the call.
IP communications constitute a connectionless network, having neither fixed addresses
nor fixed connections.
• Addressing. Each terminal on a network must be identified by a unique address.
In a voice network the unique address is a permanent attribute, based on international and
national numbering plans, and/or local telephone company practices and internal
customer-specific codes. In IP communications, dial plans track extension numbers
assigned to terminals. No fixed connection path is needed.
• Routing is related to addressing and allows connections to be established between endpoints.
Though these functions are common to data and voice networks, the implementations differ.

Overview of Voice over IP
Delay and Jitter
Data traffic is generally short and comes in bursts. Data networks like the Internet were designed to
manage these bursts of traffic from many sources on a first-come, first-served basis. Data packets are sent
to multiple destinations, often without any attempt to keep them in a particular order.
Voice networks are designed for continuous transmission during a call. The traffic is not bursty, and the
conversation uses a specific amount of bandwidth between the two ends for the duration of the call.
Several features of data networks are unsuitable for voice telephony:
• Data networks are designed to deliver data at the destination, but not necessarily within a certain
time. This produces delay (latency). In data networks, delay tends to be variable. For voice
messages, variable delay results in jitter, an audible chopiness in conversations.
• Variable routing also can result in loss of timing synchronization, so that packets are not received
at the destination in the proper order.
• Data networks have a strong emphasis on error correction, resulting in repeated transmissions.
While data network concepts include prioritization of traffic types to give some form of greater traffic
reliability (for example, for interactive transactions), data requirements tend to not be as strict as most
voice requirements.
Starting with Release 1.1, the 4600 Series IP Telephones include a dynamic jitter buffer. This feature
automatically smooths jitter to improve audio quality.
Tandem Coding
Tandem coding (also called transcoding) refers to the conversion of a voice signal from analog to digital
and back again. When calls are routed over multiple IP facilities, they may be subject to multiple
transcodings. The multiple conversions between analog and digital coding result in a deterioration in the
voice quality. Tandem coding should be avoided wherever possible in any compressed voice system (for
example, by minimizing analog trunking on the PBX).
Voice Coding Standards
There are a number of voice coding standards. The Avaya 4600 Series IP Telephones offer the options
described below:
• G.711, which describes the 64 kbps PCM voice coding technique. G.711-encoded voice is already
in the correct format for digital voice delivery in the public phone network or through PBXs.
• G.729A and G.729B, which describe adaptive code-excited linear-predictive (CELP)
compression that enables voice to be coded into 8 kbps streams.

Overview of Voice over IP (VoIP)
Overview of Voice over IP
H.323 Standard
Internal signaling provides connection control and call progress (status) information. The H.323 standard
is used for internal signaling for IP packet voice networks. H.323 defines more than simply voice. It
defines a complete multimedia network (voice, video, data), with everything from devices to protocols.
The H.245 standard links all the entities within H.323 by negotiating facilities among participants and
H.323 network elements.
The H.323 standard makes G.711 PCM compression the default form of compression. All other
compression formats are optional.
DHCP
Dynamic Host Configuration Protocol (DHCP) allows a server to assign IP addresses and other
parameters to devices such as the 4600 Series IP Telephones on an as-needed basis. This eliminates the
need to configure each end station with a static IP address. The DHCP application also passes
information to the 4600 Series IP Telephone, identifying the IP Addresses of the PBX and the TFTP
server, and the paths to the upgrade script and the application file on the TFTP server. For further
information, refer to DHCP and TFTP Servers on page 30 and DHCP on page 41.
TFTP
The Avaya 4600 IP Telephones get useful application information from the TFTP server. The telephones
also upgrade themselves using files stored on the TFTP server. While the Avaya 4600 Series IP
Telephones can operate without a TFTP server once software has been downloaded, some functionality
can be lost if the TFTP server is not available when they are reset. For further information, refer to DHCP
and TFTP Servers on page 30 and TFTP on page 52.
DNS
The Domain Name System (DNS) is a distributed Internet directory service. DNS is used mostly to
translate between domain names and IP Addresses. Release1.5 and later Avaya IP Telephones can use
DNS to resolve names into IP Addresses. In DHCP and TFTP files, DNS names can be used wherever IP
addresses were available as long as a valid DNS server is identified first (see DNS Addressing on page
69).
NAT
A Network Address Translation (NAT) is an application that can be administered between your network
and the Internet. The NAT translates network layer IP addresses so your local intranet IP addresses can
duplicate global, Internet addresses. A detailed discussion of NAT is beyond the scope of this document,
but it should be noted that use of NAT can lead to problems affecting the consistency of addressing
throughout your network. In Release 1.6 and earlier releases of the 4600 Series IP Telephones, NAT is
not recommended for networks handling IP-based telephony traffic. As of Release 1.7, all 4600 Series IP
Telephones support NAT interworking; hence, there are no problems with NAT and Release 1.7 of the
4600 Series IP Telephones. Note, however, that support for NAT does not imply support for Network
Address Port Translation (NAPT). Specifically, the 4600 Series IP Telephones do not support
communication to the PBX through any NAPT device.

Overview of Voice over IP (VoIP)
SNMP
NAT requires specific administration on the media server. The capability to have a direct Avaya IP
Telephone-to-Avaya IP Telephone call with NAT (also called “NAT shuffling”) requires Avaya
Communication Manager Release 1.3 software. See the Administration for Network Connectivity
document (listed in Related Documents on page 14).
QoS
Quality of Service (QoS) is a term covering several initiatives to maximize the quality of the voice heard
at both ends of a call that originates and/or terminates, on an IP-based telephone. These initiatives include
various prioritization schemes to offer voice packets a larger or prioritized share of network resources.
These schemes include standards such as IEEE’s 802.1D and 802.1Q, the Internet Engineering Task
Force’s (IETF’s) “Differentiated Services,” RTP Control Protocol (RTCP), Resource ReSerVation
Protocol (RSVP), and port-based priority schemes such as UDP port selection. Documentation for your
LAN equipment will elaborate on the extent your network can support any or all of these initiatives.
See Server Administration on page 37, for some implications of QoS for the 4600 Series IP Telephones.
As of Release 1.7, both the 4620 and 4630 families of IP Telephones provided network audio quality
information to the end user that may be of use to the LAN Administrator. As of Release 1.8, all 4600
Series IP Telephones provide some level of detail about network audio quality. For specific information,
see Network Audio Quality Display on 4600 Series IP Telephones on page 64.
SNMP
Simple Network Management Protocol (SNMP) is a family of standards-based protocols and procedures
to allow vendor-independent data network management. Using a simple set of protocol commands, an
SNMP-compliant device stores information in standard format in one or more Management Information
Bases (MIBs). In general, devices support the standards-specific MIB termed MIB-II. In addition,
devices may define one or more “custom MIBs” that contain information about the specifics of the
device.
As of Release 1.1, the 4600 Series IP Telephones are fully compatible with SNMPv2c (a later version of
SNMP) and with Structure of Management Information Version 2 (SMIv2), although the telephones will
respond correctly to queries from entities that comply with earlier versions of SNMP, such as SNMPv1.
“Fully compatible” means that the telephones respond to queries directed either at the MIB-II or the
Custom MIB. The 4600 Series IP Telephone Custom MIB is read-only (values therein cannot be changed
externally via network management tools).
You can restrict which IP addresses the telephone accepts SNMP queries from and you can customize
your community string with system values SNMPADD and SNMPSTAT, respectively, as indicated in
Chapter 4, “Server Administration”, Table 6, 4600 Series IP Telephone Customizable System Parameters,
on page 67.
More information about SNMP and MIBs can be found in the IETF references listed in Related
Documents on page 14. The Avaya Custom MIB for the 4600 Series IP Telephones is available for
download in *.txt format on the Avaya support Web site.

Network Assessment
Network Assessment
The current technology allows optimum network configurations to deliver VoIP with perceived voice
quality close to that of the Public Switched Telephone Network (PSTN). Not every network is able to
take advantage of packet voice transmissions. Some data networks have insufficient residual capacity for
even compressed voice traffic. In addition, the usual approach to developing data networks by integrating
products from many vendors makes it necessary to test the components for compatibility with Voice over
IP traffic.
It is assumed that your organization has performed a network assessment (with or without the assistance
of Avaya) before attempting to install Voice over IP, in order to have a high degree of confidence that the
existing data network has the capacity to carry voice packet traffic and is compatible with the required
technology.
A network assessment would include a determination of the following:
• A network audit to review existing equipment and evaluate its capabilities, including its ability to
meet planned voice and data needs.
• A determination of network objectives, including the dominant traffic type, choice of
technologies, and setting voice quality objectives.
The assessment should leave you confident that the implemented network will have the capacity for the
foreseen data and voice traffic, and can support H.323, DHCP, TFTP, and jitter buffers in H.323
applications.
It is important to distinguish between compliance with the minimal VoIP standards and support for QoS,
which is needed to run VoIP on your configuration.
TCP/UDP Port Utilization
Like most equipment in your network, the 4600 Series IP Telephones use a variety of protocols
(particularly TCP and UDP) to communicate with other equipment in that network - numerous different
types of servers, routers, other telephones, etc. Part of this communication is identification of which TCP
and/or UDP ports are to be used by each piece of equipment to support each protocol and task within the
protocol. Depending on your network, you may need to know what ports (or ranges) are used in the 4600
Series IP Telephones’ operation so that you can appropriately administer your networking infrastructure.
If so, you will find the following material useful.

Reliability and Performance
There is a cost/performance trade-off associated with Voice over IP. Greater reliability and improved
performance can be obtained through server redundancy and components with higher bandwidth
capabilities.
The reliability and performance of the traditional PBX systems have been very high. Although much of
the LAN is outside of the control of the PBX, there are several points to consider which enhance the
reliability and performance of the IP Telephone network.
All 4600 Series IP Telephones support the tools “ping” and “traceroute.” These are standard LAN/WAN
tools for identifying whether two points on a network can communicate with each other, and what path a
sample communication takes as it traverses the network from one point to the other. All 4600 Series IP
Telephones will respond appropriately to a ping or a traceroute message sent from the DEFINITY® or
MultiVantage™ switch or any other source on your network, although these telephones will not, in
general, initiate a ping or traceroute. Release 1.6 of the 4600 Series IP Telephones introduced “remote
ping” and “remote traceroute” support. The switch can instruct such a 4600 Series IP Telephone to
initiate a ping or a traceroute to a specified IP address. The telephone carries out that instruction and
sends a message to the switch informing it of the results. See your DEFINITY® or MultiVantage™
Administration documentation for more details.
As of Release 1.8, if applicable, 4600 Series IP Telephones test whether the network Ethernet switch port
supports IEEE 802.1D/q tagged frames by ARPing the router with a tagged frame (see VLAN
Considerations on page 65). If your LAN environment includes Virtual LANs (VLANs), your router will
need to respond to ARPs for VLAN tagging to work properly.

Suggestions for Installation and Configuration
IP Address Lists and Station Number
Portability
Release 1.5 of the 4600 Series Telephones provided the capability to specify IP address lists (in either
dotted decimal or DNS format) for key elements of the network, rather than merely one address for each.
Specifically, you can specify up to 127 total characters in each list of the following: router/gateways,
TFTP servers, and the media server. When the 4600 telephone is powered up or is rebooted, it attempts to
establish communication with these various network elements in turn, starting with the first address on
the respective list. If the communication is denied or times out, the telephone proceeds to the next address
on the appropriate list and tries that one. The telephone does not report failure unless all the addresses on
a given list have failed.
Obviously, this capability can significantly improve the reliability of IP telephony by maximizing the
likelihood of the telephone communicating with backup equipment if the primary equipment is down or
inaccessible (say, perhaps due to a limited network outage).
However, this capability also has the advantage of making station number portability easier. Assume a
situation where the company has multiple locations (for example, London and New York), all sharing a
corporate IP network. Users want to take their telephones from their offices in London and bring them to
New York. When users power up their telephones in the new location, the local DHCP server will
generally route them to the local switch, which denies service because it knows nothing about these new
users. However, with proper administration of the local DHCP server, the telephone knows to try a
second media server IP address, this one in London. The user can then be automatically registered with
the London switch.
Chapter 4, “Server Administration” contains details on administration of DHCP servers for lists of
alternate media servers, router/gateways, and TFTP servers. For specific information, see DNS
Addressing on page 69.
Security
In VoIP, physical wire is replaced with an IP connection. The connection is more mobile. Unauthorized
relocation of the IP telephone allows unauthorized users to send and receive calls as the valid owner. For
further details on toll fraud, refer to the DEFINITY® or Avaya Communication Manager documents in
Related Documents on page 14.
Any equipment on a data network, including a 4600 Series IP Telephone, can be the target of a Denial of
Service attack. Typically, such an attack consists of flooding the network with so many messages that the
equipment either spends so much time processing them that it cannot process legitimate tasks, or the
equipment overloads and fails. Although the 4600 Series IP Telephones cannot guarantee resistance to all
Denial of Service attacks, each Release has increasing checks and protections to resist such attacks while
maintaining appropriate service to legitimate users.
You also have a variety of optional capabilities to restrict or remove how crucial network information is
displayed or used. These capabilities are covered in more detail in Chapter 4, “Server Administration”,
and include:
• Restricting the 4600 Series IP Telephone’s responding to SNMP queries to only IP addresses on a
list you specify (as of Release 2.0).
• Specifying an SNMP community string for all SNMP messages sent by the telephone (as of
Release 2.0).

with a password (as of Release 1.8).
• Removing access to most Local (dialpad) Administration Procedures.
• Restricting the end user’s ability to view network data using a telephone Options application.
4600 Series IP Telephones
Dual Connection Architecture
Releases 1.0 and 1.1 of the 4600 Series IP Telephones use dual connection architecture to communicate
with the DEFINITY® switch. In the dual connection architecture, two station extensions must be
administered for each telephone.
Single Connection Architecture
Release 1.5 and subsequent releases of the 4600 Series IP Telephones use single connection architecture
to communicate with the Avaya media server switch. In the single connection architecture, only one
station extension must be administered for each telephone.
Registration and Authentication
The Avaya media server switch supports registering and authenticating 4600 Series IP Telephones using
the extension and password. For further information, see Related Documents on page 14.
Software
As shipped from the factory, the 4600 Series IP Telephones may not contain sufficient software for
registration and operation. When the phone is first plugged in, a software download from a TFTP server
is initiated. This gives the phone its proper functionality.
For downloads of software upgrades, the PBX provides the capability for a remote restart of the 4600
Series IP Telephone. As a consequence of restarting, the phone automatically restarts reboot procedures.
If new software is available, a download will result.
WAN Considerations
QoS is harder on a WAN than a LAN. A LAN assumes no bandwidth concerns. A WAN assumes a finite
amount of bandwidth. Therefore, QoS considerations are more significant when the IP telephony
environment includes a WAN. In addition, there are administrative and hardware compatibility issues
unique to WANs. WAN administration is beyond the scope of this document.

Overview of Voice over IP (VoIP)
Initialization Process
DHCP and TFTP Servers
The DHCP server provides the following information to the 4600 Series IP Telephone:
•
•
•
•
•
•
IP Address of the 4600 Series IP Telephone
IP Address of the Gatekeeper board on the Avaya media server.
IP Address of the TFTP server
The subnet mask
IP Address of the router
DNS Server IP Address
You should administer the LAN so that every IP Telephone can access a DHCP server with the above
information.
The IP Telephone will not function without an IP address. The failure of a DHCP server at boot time will
leave all the affected voice terminals unusable. It is possible for the user to manually assign an IP address
to an IP Telephone, but when the DHCP server finally returns, the telephone will never look for a DHCP
server unless the static IP data is unassigned manually. In addition, manual entry of IP data is an errorprone process. It is therefore strongly recommended that a DHCP server be available when the IP
Telephone reboots. If a DHCP server is not available at remote sites during WAN failures, the IP
Telephone will be unavailable after a reboot.
A minimum of two DHCP servers are recommended for reliability. A DHCP server is strongly
recommended to be available at remote sites if IP telephones are isolated from the central site DHCP
server(s) due to WAN failures.
The TFTP server provides the 4600 Series IP Telephone with a script file and, if appropriate, new or
updated application software (see Step 3: Telephone and TFTP Server on page 31 under Initialization
Process on page 30). In addition, you can edit an associated settings file to customize telephone
parameters for your specific environment (see Administering Options for the 4600 Series IP Telephones
on page 66).
Initialization Process
The following is a high-level description of the information exchanged when the telephone is initializing
and registering. This description, which assumes all equipment is properly administered ahead of time,
may be helpful in explaining how the 4600 Series IP Telephones relate to the routers and servers in your
network.
Step 1: Telephone to Network
The telephone is appropriately installed and powered. After a short initialization process, the telephone
identifies the LAN speed and sends a message out into the network, identifying itself and requesting
further information. A router in the network receives this message and relays it to the appropriate DHCP
server.

Overview of Voice over IP (VoIP)
Initialization Process
Step 2: DHCP Server to Telephone
The DHCP server provides information to the telephone, as described in DHCP and TFTP Servers on
page 30. Among other data passed to the telephone is the IP address of the TFTP server, which is crucial
for the next step.
Step 3: Telephone and TFTP Server
The telephone queries the TFTP server, which transmits a script file to the telephone. This script file, at a
minimum, tells the telephone which application file the telephone should be using (the application file is
the software that has the telephony functionality, and can be easily updated for future enhancements).
The telephone uses the script file to determine if it has the proper application file. A newly-installed
telephone may have no application file, and hence may not have the proper one. A previously-installed
telephone may or may not have the proper application file. In any event, if the telephone determines it
does not have the application file the script file says the telephone should have, the telephone requests a
download of the proper application file from the TFTP server. The TFTP server then downloads the file
and conducts some checks to ensure the file was downloaded properly. If the telephone determines it
already has the proper file, it proceeds to the next step without downloading the application file again.
After the application file has been checked and loaded, if appropriate, the 4600 Series IP Telephone also
uses the script file to determine if there is a settings file containing options you have administered for any
or all of the 4600 Series IP Telephones in your network. For more information about this settings file, see
Administering Options for the 4600 Series IP Telephones on page 66.
Step 4: Telephone and the Avaya Media Server
In this step, the telephone and the PBX exchange a series of messages which cause the display on the
telephone to prompt the user. For a new installation, the user must enter the telephone’s extension and the
media server password. For a restart of an existing installation, this information is already stored on the
telephone, but the user may have to confirm the information. The telephone and the switch exchange
more messaging, with the expected result that the telephone is appropriately registered on the switch.
More details about the installation process are available in the 4600 Series IP Telephone Installation
Guide and in Chapter 3, “Requirements” of this document.

Requirements
Introduction
The 4600 Series IP Telephones use Internet Protocol (IP) technology with Ethernet line interfaces. The IP
telephones supplement the existing Avaya IP Solutions platform. This feature provides the user with the
capability to natively administer and maintain the new 4600 Series IP Telephones.
The 4600 Series IP Telephones provide support for DHCP and TFTP over IPv4/UDP which enhance the
administration and servicing of the phones. These phones use DHCP to obtain dynamic IP addresses and
TFTP to download new versions of software for the phones.
The 4600 Series IP Telephones provide the ability to have one connection on the desktop for both the
telephone set and the PC using the telephone’s built-in hub.
Hardware Requirements
Before plugging in the 4600 Series IP Telephone, verify that all of the following requirements have been
met. Failure to do so will prevent the telephone from working and may have a negative impact on your
network.
The following hardware is required for 4600 Series IP Telephones to work properly.
NOTE:
The recommended configuration is the latest PBX software and the latest IP Telephone
firmware. In the event your site does not have the latest PBX software, follow the
recommendations in the table immediately below.

Additional Hardware Requirements
• Be sure the appropriate circuit pack(s) are administered on your media server. See the media
server’s hardware guide for more detail.
• A Category 5e LAN. If the telephones are to be powered from the LAN, the power supply must be
designed to the IEEE 802.3af-2003 standard for LAN powering.
• Electrical power provided to each phone by one of the following two sources:
— A Telephone Power Module (DC power jack). This module must be ordered separately,
except for the 4630, which comes with its own power brick and the 4690, which has its
own power interface module. Note that the 4630SW does not come with a power brick,
which must be ordered separately if LAN powering will not be used for that particular
telephone model.
— IEEE 802.3af-2003, if the LAN supports this powering scheme (note that the 4630 and
4690 cannot be powered this way, but the 4630SW can be powered this way).
• Verify that the 4600 Series IP Telephone package includes the following components:
— 1 telephone set
— 1 telephone handset (except the 4690 IP Conference Telephone)
— 1 H4DU 9-foot long (when extended) 4-conductor coiled handset cord, plugged into the
telephone and the handset, except for the 4690 IP Conference Telephone
— 1 Category 5 modular line cord for the connection from the IP Telephone to the Ethernet
wall jack
— 4600 Series IP Telephone Safety Instructions (555-233-779)
— Power Interface Module (4690 IP Conference Telephone only)
— Power Brick (4630 IP Telephones only)
— Stylus (4630/4630SW IP Telephones only)
• You may need a Category 5e modular line cord for the connection from the 4600 Series IP
Telephone to the PC.
Refer to the 4600 Series IP Telephone Installation Guide.
The IP telephones work the same on all Avaya media servers running Avaya Call Processing (ACP) R8.4,
R9, R9.5, and R10, or Avaya Communication Manager 1.1, 1.2, 1.3, and 2.0, unless otherwise specified.

Software Requirements
Software Requirements
The following software is required for 4600 Series IP Telephones to work properly:
• The DHCP server and application should be installed and properly administered, as described in
DHCP on page 41.
CAUTION:
A DHCP server is not mandatory, but static addressing is necessary when a DHCP server
is unavailable. Due to the difficulties associated with static addressing, it is very strongly
recommended that a DHCP server be installed and that static addressing be avoided.
• The TFTP server and application must be installed and properly administered, as described in
TFTP on page 52.
CAUTION:
A TFTP server does not need to be available for the Avaya IP Telephones to operate. The
Avaya IP Telephones obtain important information from the script files on the TFTP
server and depend on the TFTP file for software upgrades. If the TFTP server is not
available when the Avaya IP Telephones reset, they will register with the media server and
operate. Some features may not be available, and restoring those features will require
resetting the Avaya IP Telephone(s) when the TFTP server is available.
• For 4630 and 4630SW IP Telephone environments, if users are to have access to LDAP
directories or corporate web sites, the appropriate servers must be in place, and the 4630/4630SW
telephones must be appropriately administered in accordance with Server Administration on page
37.
CAUTION:
4630 IP Telephone Release 1.72 introduced significant software architecture changes.
Thus, unlike most 4600 Series IP Telephones software releases, 4630 IP Telephone
Release 1.72 and later cannot be downgraded to a release earlier than 1.72. Attempting to
do so will render the 4630 (and 4630SW, if Release 1.8 or greater) set inoperable. In
addition, if you are upgrading a 4630 from a release prior to Release 1.61, you must first
upgrade to Release 1.61, and then upgrade to the newer Release. You cannot upgrade
directly from a pre-1.61 Release to a post-1.61 Release for the 4630.
• For 4610SW/4620/4620SW IP Telephone environments, if users are to have access to LDAP
directories or corporate WML web sites, the appropriate servers must be in place, the LDAP
Directory Application software must be downloaded from the Avaya support web site, and the
4610SW/4620/4620SW telephones must be appropriately administered in accordance with Server
Administration on page 37.
NOTE:
Ensure that all required parameters are configured correctly. For Avaya media server
information, see your administration documentation. For the DHCP and TFTP servers, see
Server Administration on page 37.

Server Administration
Introduction
When a 4600 Series IP Telephone is plugged in and powered, it automatically negotiates with its
associated LAN to determine the Ethernet speed. From that point on, the actions taken by the phone
depend in large part on the administration of the network before the phone is installed, and on the actions
taken, if any, by the installer. This chapter discusses in detail the parameters and other data the telephone
needs to operate and the alternatives for delivering that information to the telephone, where appropriate.
Recommendations and specifications for alternatives to certain parameters are also provided.
The parameters under which the phone needs to operate are summarized as follows:
•
•
•
•
•
•
•
Telephone Administration on the media server.
IP address management for the telephone.
Tagging Control and VLAN administration for the telephone, if appropriate.
Quality of Service (QoS) administration for the telephone, if appropriate.
Site-specific Option Number (SSON) setting of DHCP servers, if appropriate.
Interface administration for the telephone, if appropriate.
Application-specific administration for the telephone, if appropriate (for example, Directory- or
Web-specific information required for these optional applications).
The delivery mechanisms are:
•
•
•
•
Maintaining the information on the Avaya media server.
Manually entering the information via the telephone dialpad.
Administering the DHCP Server.
Editing the settings file on the TFTP Server.
These parameters can be administered in a variety of ways, as indicated in Table 1, below. Note that not
all parameters can be administered on all delivery mechanisms.

General information about administering DHCP servers is covered in DHCP and TFTP on page 40, and
more specifically, DHCP on page 41. General information about administering TFTP servers is covered
in DHCP and TFTP, and more specifically, TFTP on page 52. Once you are familiar with that material,
you will be able to administer options on the telephone in accordance with Administering Options for the
4600 Series IP Telephones on page 66.
NOTE:
If a given parameter is administered in multiple places, the last server to provide the
parameter has precedence. The sequence is: manual administration, DHCP, TFTP, and
then the media server. That means, for parameters downloaded by the media server, any
previous settings, including manual settings, are overwritten by the setting the Avaya IP
Telephone receives from the media server. The only exception to this sequence is in the
case of VLAN IDs. In the case of VLAN IDs, the usual sequence applies through TFTP. If
the VLAN ID after TFTP is non-zero, any VLAN ID from the media server is ignored.

Server Administration
DHCP and TFTP
DHCP and TFTP
Dynamic Host Configuration Protocol (DHCP) provides a means by which configuration parameters can
be automatically assigned to clients on a TCP/IP network. This minimizes the maintenance of a 4600
Series IP Telephone network by removing the need to individually assign and maintain IP addresses and
other parameters for each IP telephone on the network.
Software Checklist
Please make sure that you have purchased and/or own licenses to install and use the DHCP server and
TFTP server software.
NOTE:
It is possible to install both the DHCP server and the TFTP server on the same machine.
CAUTION:
The circuitry in the 4600 Series IP Telephones reserves IP addresses of the form
192.168.2.x for internal communications. The telephone(s) will not properly use addresses
you specify if they are of that form.
Required Network Information
DHCP is the control point where an enterprise controls its IP Telephones. Before administering DHCP
and TFTP, complete the information in Table 2, Required Network Information Before Installation - Per
DHCP Server, on page 41 below to ensure that you have the necessary information regarding your
network. There may be more than one Gateway, TFTP server, subnet mask and Gatekeeper in your
configuration. You will need a copy of this table for each DHCP server.
Release 1.5 of the 4600 Series Telephones supported the ability to specify a list of IP addresses for a
gateway/router, TFTP server, and Avaya media server Gatekeeper(s), as explained in Overview of Voice
over IP on page 19. Each list may contain up to 127 total ASCII characters, with IP addresses separated
by commas with no intervening spaces.
When specifying IP addresses for the TFTP server or media server, you can use either dotted decimal
format (“xxx.xxx.xxx.xxx”) or DNS names to identify the address(es). If you use DNS, note that the
system value DOMAIN will be appended to the IP addresses you specify. If DOMAIN is null, the DNS
names must be fully qualified, in accordance with IETF RFCs 1034 and 1035. For more specific
information about DNS, see DHCP Generic Setup on page 42 and DNS Addressing on page 69.

This section provides basic information on DHCP servers and generic information on DHCP server
administration.
Choosing a DHCP Configuration
A discussion on how to best set up your network to work with the 4600 Series IP Telephones is beyond
the scope of this document. See Network Assessment on page 23. This document concentrates on the
simplest case of the single LAN segment. Information provided here can be extrapolated for more
complex LAN configurations.
CAUTION:
Before you start, it is important that you understand your current network configuration.
An improper installation can cause network failures or reduce the reliability and
performance of your network.

DHCP Software Alternatives
Two DHCP software alternatives are common to Windows operating systems:
• Windows NT® 4.0 DHCP Server
• Windows 2000® DHCP Server
Any other DHCP application may work.
It is the customer’s responsibility to install and configure the DHCP server correctly. This document is
limited to describing a generic administration that will work with the 4600 Series IP Telephones.
DHCP Generic Setup
Set up of a DHCP server involves the following phases:
1
2
Installing the DHCP server software according to vendor instructions.
Configuring the DHCP server with the following information:
• IP addresses available for the 4600 Series IP Telephones.
• The following DHCP options:
— Option 1 (Subnet mask) (Table 2, Required Network Information Before
Installation - Per DHCP Server, on page 41, item 3).
— Option 3 (Gateway [router] IP address[es]) (Table 2, Required Network
Information Before Installation - Per DHCP Server, on page 41, item 1). If more
than one address is listed, the total list may contain up to 127 total ASCII
characters, with IP addresses separated by commas with no intervening spaces.
— Option 6 (DNS server[s] address list). If more than one address is listed, the total
list may contain up to 127 total ASCII characters, with IP addresses separated by
commas with no intervening spaces. At least one address in Option 6 must be a
valid, non-zero, dotted decimal address - otherwise, DNS will fail.
— Option 15 (DNS Domain Name). This string should contain the domain name to be
used when DNS names in system parameters are resolved into IP addresses. This
domain name is appended to the DNS name before the 4600 IP Telephone attempts
to resolve the DNS address. Option 15 is necessary if you wish to use a DNS name
for the TFTP server; otherwise, you may specify a DOMAIN as part of TFTP
customization, as indicated in DNS Addressing on page 69.
— Option 51 (DHCP lease time), if desired. Six weeks or greater is recommended.
Expired leases will cause Avaya IP Telephones to reboot. It is highly desirable to
provide enough leases so that an IP Telephone’s IP Address does not change if it is
briefly taken off-line.
NOTE:
The DHCP standard states that when a DHCP lease expires, the device should
immediately cease using its assigned IP Address. This is not necessarily the desired
behavior for telephones, especially if a user is on a call. If the network has problems and
the only DHCP server is centralized, not accessible to the given telephone, the telephone
is no longer usable until the server can be reached.
42
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide
July 2004
Server Administration
DHCP
It might be preferred that, once assigned an IP address, the telephone continues using that
address after the DHCP lease expires, until a conflict with another device is detected. As
indicated Table 6, 4600 Series IP Telephone Customizable System Parameters, on page
67, the system parameter DHCPSTD allows an administrator to specify either that the
telephone should comply with the DHCP standard (DHCPSTD set to “1”), or that the
telephone should continue using its IP address after the DHCP lease expires (DHCPSTD
set to “0”). The latter case is the default, and if invoked, the telephone sends an ARP
Request for its own IP address, every five seconds after the DHCP lease expires, either
forever, or until it receives an ARP REPLY. In this latter case, the telephone displays an
error message, sets its IP Address to 0.0.0.0, and attempts to contact the DHCP server
again.
— Option 52 (Overload Option), if desired. If this option is received in a message, the
telephone interprets the sname and file fields in accordance with RFC 2132,
Section 9.3.
— Option 58 (DHCP lease renew time), if desired.
— Option 59 (DHCP lease rebind time), if desired.
— Option 66 (TFTP Server Name).
NOTE:
Microsoft DHCP servers support only dotted-decimal format for TFTP addresses, not
symbolic names. Option 66 need not be used if the TFTP server is identified in the Site
Specific Option string (Option 176). However, to simplify configuration, we recommend
that you use Option 66. If you use both Option 66 and Option 176 to identify TFTP
servers, the value(s) in Option 176 will override the value(s) in Option 66.
— A 4600 Series IP Telephone-specific DHCP option specifying information such as
TFTP server and Avaya Media Server Gatekeeper IP addresses. Use the sitespecific option (SSON) at #176. The value for this option should be set to either of
the following strings:
MCIPADD=xxx.xxx.xxx.xxx,MCPORT=yyyy,TFTPDIR=<path>,TFTPSRVR=
zzz.zzz.zzz.zzz
OR
MCIPADD={list of DNS names}, MCPORT=yyyy, TFTPDIR=<path>, TFTPSRVR=
{list of DNS names}
NOTE:
The TFTPDIR value should be listed before the TFTPSRVR, if the latter is specified in the
SSON.

The 4600 Series IP Telephones do not support Regular Expression Matching, and therefore, do not use
wildcards. See Administering Options for the 4600 Series IP Telephones on page 66.
In configurations where the upgrade script and application files are in the default directory, the
TFTPDIR=<path> should not be used.
You do not have to use Option 176, but if you do not use it, you must ensure the key information
(TFTPSRVR, MCIPADD, and MCPORT, especially) is administered appropriately elsewhere. For
example, if the DNS server is specified in Option 6, and the Domain Name is specified in Option 15, you
can use the configured names “AvayaTFTPServer” and “AvayaCallServer” for TFTPSRVR and
MCIPADD, respectively. Upgrading from IP Telephone Releases prior to R1.60 requires Option 176 to
be administered with, at a minimum, MCIPADD.
DHCP servers should be administered to deliver only the options specified in this document.
Administering additional, unexpected options may have unexpected consequences, including possibly
causing the IP Telephone to ignore the DHCP server.
The Media Server Name, TFTP Server Name, and SMTP Server Name must each be no more than 32
characters in length.
NOTE:
Examples of good DNS administration include the following:
- Option 6: “aaa.aaa.aaa.aaa”
- Option 15: “dnsexample.yourco.com”
- Option 66: “tftpserver.yourco.com,zzz.zzz.zzz.zzz”
- Option 176: “MCIPADD=xxxx.xxx.xxx.xxx”
Depending on the DHCP application you choose, you should be aware of the fact that the
application most likely will not immediately recycle expired DHCP leases. An expired
lease may remain reserved for the original client for a day or more (for example,
Windows NT® DHCP reserves expired leases for about one day). The intent of this
reservation period is to protect a client’s lease in case the client and the DHCP server are
in two different time zones, the computers’ clocks are not in synch, or the client is not on
the network when the lease expires.
The implication of this fact may be seen in the following example: Assume 2 IP addresses
(hence two possible DHCP leases) and three IP telephones, two of which are using the two
available IP addresses. When the lease expires for the first two telephones, the third will
not be able to get a lease (even if the other two telephones have been removed from the
network) until the reservation period expires.
The 4600 Series IP Telephone sets the indicated system values to the values of the indicated fields of the
DHCPACK message as indicated in Table 3 below.

Verify that Microsoft DHCP Server is listed as one of the Network Services on the Services tab.
If it is listed, go to the section Initial Configuration below. If it is not listed, then install the DHCP
server.
Initial Configuration
The Windows NT® 4.0 DHCP server configuration involves setting up a scope for the IP telephone. A
DHCP scope is essentially a grouping of IP devices (in this case IP telephones) running the DHCP client
service in a subnet. The scope is used to define parameters for each subnet. Each scope has the following
properties:
• A unique subnet mask used to determine the subnet related to a given IP address.
• A scope name assigned by the administrator when the scope is created.
• Lease duration values to be assigned to DHCP clients with dynamic addresses.
In addition, the DHCP server can assign configuration parameters to a client, and these can be specified
for each individual DHCP scope.
Setting up the Windows NT® 4.0 DHCP server requires the following steps:

This section describes how to set up a TFTP server for downloading software updates to the 4600 Series
IP Telephones.
CAUTION:
The files defined by the TFTP server configuration have to be accessible from all IP
Telephones. Ensure that the filenames match the names in the upgrade script, including
case, since UNIX systems are case-sensitive.
NOTE:
You can use any TFTP application you want. However, we strongly recommend using the
TFTP application available for free download at http://www.avaya.com/support or the
TFTP server capability on the S8300’s media server. The Avaya support site also contains
instructions for installing and configuring the Avaya TFTP server.
TFTP Generic Setup
The following phases are involved in setting up a TFTP server.
• Install the TFTP server software. The section below describes how to install and configure
Avaya’s TFTP application.
• Configure the file path parameter to the directory where the files are to be stored. This is the file
path in Table 2, Required Network Information Before Installation - Per DHCP Server, on page
41. For increased security, it is also recommended that you disable the ability to upload to the
server. Note that this option may be not available to all TFTP servers.
• Download the upgrade script file and application file from the Avaya Web site
(http://www.avaya.com/support) to the directory as specified by the file path.
NOTE:
Many LINUX servers distinguish between upper and lower case names. Be sure to
accurately specify the 46xxsettings filename, as well as the names and values of the data
therein.

TFTP Server on S8300 Media Server
The S8300 Media Server includes the capability to provide all the TFTP support required for the 4600
Series IP Telephones. In addition, the media server has an easy to use, PC-based interface for creating
script files. Thus, you do not need to manually create the text files discussed in 4600 Series IP Telephone
Scripts and Application Files because the media server creates the files for you. For more information
about the media server, please see Installation and Upgrades for Avaya G700 Media Gateway and Avaya
S8300 Media Server, mentioned in Related Documents.
Table 6, Table 7, and Table 8 in this chapter list the various parameters you can administer when
manually creating the TFTP script file, as discussed in 4600 Series IP Telephone Scripts and Application
Files. When using the media server, you don’t need to worry about the specific parameter names, since
the media server handles that for you. For information, however, Table 4 lists the parameter names from
4600 Series IP Telephone Scripts and Application Files and indicates the corresponding field name from
the media server’s TFTP server application. Any limits, restrictions, etc. on the parameters are built into
the media server.

NOTE:
The 4630 telephones have a different upgrade process than the other telephones. This is
because the 4630 touch screen operation is significantly more complex than any of the
other Avaya IP Telephones. There are some common elements between the 4630 and other
IP Telephones; any differences are highlighted as appropriate in this section.
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide

Server Administration
4600 Series IP Telephone Scripts and Application Files
• An upgrade script file, which tells the IP telephone whether it needs to upgrade software. The
Avaya IP Telephones attempt to read this file every time they reset. The upgrade script file is also
used to point to the settings file. There are separate upgrade script files for the 4630 telephones.
• The settings file contains the option settings that enable many of the options you will need to
customize the Avaya IP Telephones for your enterprise. You can use one settings file for all of
your Avaya IP Telephones.
In addition to the upgrade script and settings files you need the latest binary code used in the Avaya IP
Telephones.
These files are available from the Avaya Web site, thereby allowing you to upgrade to new software
releases and new functionality without having to replace IP telephones. In general, all these files, plus
other useful information such as a ReadMe file, information about infrared capabilities, and a template
for the settings file, are contained in a self-extracting executable file (in both zipped and unzipped format)
you can download to your TFTP server. Application files for all current 4600 Series IP Telephones
(including the 4630/4630SW as of Release 2.0), and an upgrade script file, are bundled together in that
self-extracting executable file. See Choosing the Right Application File and Upgrade Script File on page
57 for more information.
The Avaya-provided upgrade script files, and the binaries included in the zip files, are designed to
upgrade the Avaya IP Telephones. You should not need to modify them. It is essential that all of the
binary files be together on the TFTP server. When downloading a new release onto a TFTP file server
with an existing release already on it, we recommend that you:
•
•
•
•
Stop the TFTP server.
Back up all the current TFTP directories.
Copy your 46xxsettings.txt file to a backup location.
Remove all of the files in the download directory. This will ensure you do not have an
inappropriate binary or configuration file on the server.
• Download the self-extracting executable file (or zip file if you prefer).
• Extract all of the files. When extracting the 4630 files, be sure to allow the directories to be
created.
•
•
•
•
•
Copy your 46xxsettings.txt file back into the download directory.
Check the Readme files for release-specific information.
Modify the 46xxsettings.txt file as desired.
Restart the TFTP Server.
Reset your Avaya IP Telephones.
You can download a default upgrade script file, sometimes called merely the “script file,” from
http://www.avaya.com/support. This file is sufficient to allow the telephone to use default settings for
customer-definable options, although of course these settings can also be changed with DHCP or in some
cases, from the telephone’s dialpad itself. However, you might want to open the default file and
administer the options to add useful functionality to your Avaya IP Telephones. This file must reside in
the same directory as the upgrade script file, and must be called 46xxsettings.scr or 46xxsettings.txt. The
Avaya IP Telephones can operate without this file.
NOTE:
Most Windows systems interpret the file extension *.scr as a screen saver. The 4600 IP
Telephones originally used *.scr to indicate a script file, but starting with Release 1.7, the
settings file can also have the extension *.txt.

The settings file may include any of the five types of statements, one per line:
• Comments, which are statements with a “#” character in the first column.
• Tags, which are comments that have exactly one space character after the initial #,
followed by a text string with no spaces.
• Goto commands, of the form GOTO tag, which cause the telephone to continue
interpretation of the settings file at the next line after a # tag statement. If no such
statement exists, the rest of the settings file is ignored.
• Conditionals, of the form IF $name SEQ string GOTO tag, which cause the GOTO
command to be processed if the value of name is a case-insensitive equivalent to string. If
no such name exists, the entire conditional is ignored.
• SET commands, of the form SET parameter_name value, where invalid values cause the
specified value to be ignored for the associated parameter_name (so the default or
previously administered value is retained). All values should be text strings, even if the
value itself is numeric, a dotted decimal IP address, etc.
NOTE:
All data should be enclosed in quotation marks for proper interpretation.
The Avaya-provided upgrade script file includes lines that tell the telephone to GET 46xxsettings.scr and
46xxsettings.txt. These lines cause the telephone to use TFTP to attempt to download the file specified in
the GET command. If the file is successfully obtained, its contents are interpreted as an additional script
file - that is how your settings are changed from the default settings. If the file cannot be obtained, the
telephone continues processing the upgrade script file (so if you do not have a 46xxsettings.scr file, the
telephone will look for a 46xxsettings.txt file). If the settings file is successfully obtained but does not
include any setting changes (which is the case when you initially download the script file template from
the Avaya Support Web site, before you make any changes), the telephone stops using TFTP (and hence,
does not go back to the upgrade script file).
You can change the name of the settings file, if desired, as long as you also edit the corresponding GET
command in the upgrade script file. In general, however, you are encouraged not to alter the Avayaprovided upgrade script file; if Avaya changes the upgrade script file in the future, any changes you have
made will be lost. You are strongly encouraged to use the 46xxsettings file to manage your customization
instead.
For more details on customizing your settings file, see Contents of the TFTP Settings File.
Choosing the Right Application File and
Upgrade Script File
As mentioned in 4600 Series IP Telephone Scripts and Application Files, the 4600 IP Telephone software
Releases are bundled together in *exe and *zip files on the Avaya support Web site. As of Release 2.0,
there are 4 “bundles” from which to choose - only one bundle is likely to be optimal for any one
environment.
Which bundle to choose depends on the answer to two questions:
• Which version of 4610SW/4620SW software do you need in that environment?
• Are the majority of your 4602/4602SW telephones in that environment H.323-based or SIPbased?

4600 Series IP Telephone Scripts and Application Files
The 4610SW/4620SW IP Telephone supports multi-byte characters, so the software bundles come in one
of three versions: a default version (which only supports single-byte characters like those used in English,
French, Japanese Katakana, etc.), a multi-byte version for 4610SW/4620SWs that supports Chinese and
Russian, and a separate multi-byte version for 4610SW/4620SWs that supports Japanese and Russian. If
multi-byte support is not relevant to you, you want the default bundle, even if you do not have any
4610SW/4620SWs. Otherwise, you want the software bundle that includes Chinese or Japanese, as
appropriate.
NOTE:
All bundles include the complete software for the other, non-4610SW/4620SW
telephones (including the 4620 but not including the 4630/4630SW, which remains
separate). The only differences between the three bundles are the software for the
4610SW/4620SW, and a slight change in the associated upgrade script file.
The 4602 IP Telephones can support either H.323 or SIP signaling protocol. If a majority of your 4602s
are H.323-based (the standard), or if you have no 4602s at all, you can use any of the software bundles
identified above. If a majority of your 4602s are SIP-based, you want the fourth software bundle,
identified as the “SIP” software bundle on the Web site. The application files in this SIP bundle are the
same as in the default bundle, but the upgrade script file in the SIP bundle has been modified to assume
that SIP is the default protocol for 4602s, and that H.323 is the exception.
If your environment contains a mixture of 4602 H.323 and SIP telephones, you will want to use the SIG
system value to ensure each of those telephones have their appropriate software downloaded. The SIG
system value has three legal values: the default value “0” (meaning “use the default protocol”), “1”
meaning “use H.323”, and “2” meaning “use SIP.” You decide the meaning of “the default protocol” - if
the majority of your 4602 IP telephones are H.323-based, that should be the default, otherwise, SIP is the
default.
The SIG system value cannot be set in the 46xxsettings file or in the upgrade script file - only on
a phone-by-phone basis. Instead, you should first instruct the installers of the non-default phones (that is,
for installations of SIP phones in a largely H.323 environment, or vice versa) to carry out the SIGnaling
Protocol Identifier procedure specified in Chapter 3 of the 4600 Series IP Telephone Installation Guide.
For example, if yours is a largely H.323 environment for 4602s, when SIP phones are installed the SIG
system value should be set to “2”. If yours is a largely SIP environment for 4602s, when H.323 phones
are installed the SIG system value should be set to “1”.
More detailed information about SIP is available in the SIP-related documentation, provided elsewhere
on the Avaya support Web site.
NOTE:
As indicated above, although the SIG system value is a Release 2.0 feature, the 4601 IP
Telephone supports SIG functionality, even though the 4601 currently supports only
Release 1.8 software.

The GROUP System Value
The GROUP System Value
There may be situations where you have different communities of end users, all of which have the same
model telephone, but which require different administered settings. For example, you might want to
restrict Call Center agents from having the ability to Logoff, yet that might be an essential capability for
“hot-desking” associates.
As of Release 2.0, the simplest way to separate groups of users is by associating each of them with a
number, and editing the 46xxsettings file so that each group is assigned the appropriate settings. The
GROUP system value is used for this purpose. The GROUP system value cannot be set in the
46xxsettings file - only on a phone-by-phone basis. Instead, you should first identify which phones are
associated with which group, and designate a number for each group. The number can be any integer
from 0 to 999, with 0 as the default (i.e., your largest group would be assigned as Group 0).
Then, at each non-default phone, instruct the installer or end-user to invoke the GROUP Local (dialpad)
Administrative procedure as specified in the 4600 Series IP Telephone Installation Guide and specify
which GROUP number to use. Once the GROUP assignments are in place, edit the settings file to allow
each telephone of the appropriate group to download its proper settings. For example, the settings file
could look like:
IF $GROUP SEQ 1 goto CALLCENTER
IF $GROUP SEQ 2 goto HOTDESK
{specify settings unique to Group 0}
goto END
# CALLCENTER
{specify settings unique to Group 1}
goto END
# HOTDESK
{specify settings unique to Group 2}
# END
{specify settings common to all Groups}

QoS
QoS
The 4600 Series IP Telephones support both IEEE 802.1D/Q and DiffServ, and in the future may support
other, possibly proprietary, procedures for implementing Quality of Service. In addition, other networkbased QoS initiatives such as UDP port selection do not require support by the telephones, but
nonetheless can contribute to improved QoS for the entire network.
IEEE 802.1D and 802.1Q
IEEE’s 802.1Q standard defines a tag that can be added to voice and data packets. Most of the
information associated with this tag deals with Virtual LAN (VLAN) management, but 3 bits are reserved
for identifying packet priority. These 3 bits allow any one of 8 priorities to be assigned to a specific
packet. As defined in the standard, the 8 priorities are, from highest to lowest:
•
•
•
•
•
7: Network management traffic
6: Voice traffic with less than 10ms latency
5: Voice traffic with less than 100ms latency
4: “Controlled-load” traffic (mission-critical data applications)
3: Traffic meriting “extra-effort” by the network for prompt delivery (for example, executives’
e-mail)
• 2: Reserved for future use
• 0: Traffic meriting the network’s “best-effort” for prompt delivery (the default priority)
• 1: Background traffic such as bulk data transfers and backups
NOTE:
Priority 0 is a higher priority than Priority 1.
To support IEEE 802.1D/Q, the 4600 Series IP Telephones can be administered either from the network
via appropriate administration of the DHCP or TFTP servers, or at the telephone itself via dialpad input.
Specific implementation details for local administration are in the Installation Guide, and for remote
administration are in this chapter, in 4600 Series IP Telephone Scripts and Application Files on page 55.
In summary, four IEEE 802.ID/Q QoS parameters in the telephones can be administered. These
parameters are:
• L2QVLAN: setting the VLAN ID on which the telephone should operate. For example, what
VLAN ID to use for DHCP Discovery, etc. (up to 4 digits, from 0 to 4094, default is 0).
• VLANTEST: setting the number of seconds to wait for a DHCPOFFER when using a non--zero
VLAN ID (up to 3 digits, from 0 to 999, default is 60).
• L2QAUD: setting the 802.1Q audio priority value (between 0 and 7, default is 6)
• L2QSIG: setting the 802.1Q signaling priority value (between 0 and 7, default is 6)
In the 4600 Series IP Telephone Installation Guide, the Local Administrative Option for specifying
ADDResses also allows you to specify VLAN IDs and VLANTEST values (see also VLAN
Considerations on page 65). The Local Administrative Option for specifying QoS values allows you to
specify values for L2QAUD and L2QSIG.
The 4600 Series IP Telephones can simultaneously support receipt of packets using, or not using, 802.1Q
parameters.

QoS
DIFFSERV
As defined in IETF RFCs 2474 and 2475, “services” are basically ways of treating different subsets of a
network’s traffic in different ways at the Internet Protocol (IP) layer, Layer 3. For example, some packets
might be routed in such a way as to expedite delivery (minimize delay), while others are routed to
minimize loss, minimize cost, etc. The differentiation between these services (that is, Differentiated
Services) is provided by a redefinition of an octet in the Layer 3 headers for IP versions 4 and 6, also
termed IPv4 and IPv6, respectively. This octet is called a Type of Service (TOS) octet in IPv4 and a
Traffic Class octet in IPv6, but in both cases the octet is interpreted differently than it was originally
defined. With Differentiated Services, bits 0 through 5 of the octet identify a Differentiated Services Code
Point (DSCP) that identifies a procedure to be used to handle that packet on a per-hop basis. Bits 6 and 7
of the octet are currently unused, and are ignored by DSCP-compliant routers.
With DiffServ, the default DSCP is all zeroes, and represents “no special handling.” RFC 2474 also
defines eight “Class Selector Codepoints,” which are the eight DSCP encodings that can be represented
by xxx000 (where “x” represents one bit). These Code Selector Codepoints are considered prioritized,
with the larger numerical values having a higher relative order. DSCP-compliant routers should treat
larger-valued DSCPs in such a way as to give the associated packets a “probability of timely forwarding”
greater than a packet with a lower-valued DSCP. In addition to the eight Class Selector Codepoints, a
network may define its own DSCPs by defining encodings that do not terminate in 000. The specific
treatment intended by these custom DSCPs will not necessarily be carried out by routers outside the
customer’s own network.
In the 4600 Series IP Telephone Installation Guide, the Local Administrative Option for QoS allows you
to specify Diffserv values for Layer 3 audio (“L3QAUD”) and signaling traffic (“L3QSIG”) on a phoneby-phone basis if necessary.
The Avaya IP Telephones’ DiffServ values will be changed to the values administered on the media
server as soon as the phone is registered. For more information, see the document titled Administration
for Network Connectivity (555-233-504). Unless there is a specific need in your enterprise LAN, we do
not recommend you change the default values.
UDP Port Selection
Some data networks include equipment that can perform UDP port selection. This is a mechanism by
which packets with port numbers in a given range are given priority over packets with port numbers
outside that range.
To support UDP port selection, the 4600 Series IP Telephones can be administered either from the Avaya
Communication Manager Network Region form, or at the telephone itself via dialpad input. Specific
implementation details for local administration of MCPORT are in the 4600 Series IP Telephone
Installation Guide, and, for Avaya Communication Manager administration, are in Administration for
Network Connectivity for Avaya Communication Manager Software. In summary, the system value
MCPORT represents the port on the TN2302AP board. This port number can be used to administer
routers, etc. that support UDP port selection, to maximize the priority given to the voice packets being
exchanged between the PBX and the telephone.
The default value for MCPORT is 1719. The switch must be administered to use a port within the proper
range for the specific LAN, and the IP Telephone(s) will copy that port. A related parameter is
PORTAUD, which is the RTP port used by the switch. In accordance with standards RFC 1889 and 1890,
the IP Telephone uses a default value for PORTAUD of 5004.

As of Release 1.7 for the 4620 and 4630/4630SW telephones, and as of Release 1.8 for the
4602/4602SW/4610SW/4620SW IP Telephones, the telephone is by default administered to offer the end
user an opportunity to monitor network audio performance while on a call. The user guides for each
phone go into specific detail on how the user gets to the appropriate screen; this document tells you what
the end user can see, and what it means.
For 4610SW/4620/4620SW/4630/4630SW IP Telephones, the following parameters are displayed in
real-time to users on the appropriate screens, while on a call:
Table 5: Parameters in Real-Time

Possible Values
Audio Connection
Present?
Yes (if a receive RTP stream has been established)
No (if a receive RTP stream has not been established)
Received Audio
Coding
G.711 or G.729
Silence
Suppression
Yes (if the telephone knows the far-end has silence suppression Enabled)
No (if the telephone knows the far-end has silence suppression Disabled, or the
telephone does not know either way)
Packet Loss
No data or a decimal percentage. Late and out-of-sequence packets are counted
as lost if they are discarded. Packets are not counted as lost until a subsequent
packet is received and the loss confirmed by the RTP sequence number.
Packetization
Delay
No data or an integer number of milliseconds. The number reflects the amount
of delay in received audio packets, and includes any look-ahead delay
associated with the codec.
One-way Network
Delay
No data or an integer number of milliseconds. The number is one-half the value
RTCP computes for the round-trip delay.
Network Jitter
Compensation
Delay
No data or an integer number of milliseconds reporting the average delay
introduced by the telephone’s jitter buffer.
For 4602/4602SW IP Telephones, the Network Audio Quality Screen presents the user with a qualitative
assessment of the overall audio quality currently being experienced. This assessment is based on separate
evaluations of the Packet Loss and the total Network Delay (the sum of Packetization Delay, One-way
Network Delay, and Network Jitter Compensation Delay), and consideration of the codec in use. You can
disable the display of the Network Audio Quality data and assessment for all sets by setting the system
value NTWKAUDIO to a value of “0” as explained in Administering Options for the 4600 Series IP
Telephones on page 66.
The implication of this information for LAN administration depends, of course, on the values reported by
the user and the specific nature of your LAN (topology, loading, QoS administration, etc.). The major use
for this information is to give the user an idea of how network conditions are affecting the audio quality
of the current call. It is assumed you have more detailed tools available for troubleshooting the LAN.

VLAN Considerations
RSVP and RTCP
Avaya IP Telephones implement the Resource ReSerVation Protocol (RSVP) to support WAN bandwidth
management. RSVP is administered from the media server. Avaya IP Telephones implement the RTP
Control Protocol (RTCP) so that Avaya’s Voice over IP (VoIP) Monitoring Manager (VMON) software
can provide real-time monitoring and historical data of the audio quality of VoIP calls.
Resource ReSerVation Protocol (RSVP) is an IETF-standard protocol used by hosts to request resource
reservations throughout a network. RSVP-compliant hosts send messages through a network to receivers,
which respond with messages requesting a type of service and an amount of resources (e.g., bandwidth)
to carry out that service. The host is responsible for admitting (approving) or rejecting (denying) the
request. In a QoS context, RSVP is used to try to reserve bandwidth in the network for voice calls, on a
call-by-call basis. If insufficient bandwidth is available for the target voice quality, a request to use
network bandwidth for a voice call will be rejected.
RTP Control Protocol (RTCP), as its name implies, is a protocol that provides control functions for Realtime Transport Protocol (RTP). RTP provides end-to-end network services for real-time data (such as
Voice over IP), but does not provide a reservation function, nor does it guarantee any level of QoS. RTCP
supplements RTP by monitoring the quality of the RTP services and can provide real-time information to
users of an RTP service. In a QoS context, RTCP is valuable for identifying information such as packet
loss, 1-way delay (how long a packet has to go from source A to destination B), jitter, etc. RTCP itself
does not improve QoS, but it provides information to help identify where problem areas might be.
You cannot change the telephone’s RSVP or RTCP parameters directly on the telephone or via TFTP or
DHCP administration. The only way to change these parameters is by appropriate administration of the
switch. See your Avaya media server administration material for more detail.
VLAN Considerations
If your LAN environment does not include Virtual LANs (VLANs), ignore this section. Otherwise, this
section contains information on how to administer 4600 Series IP Telephones to minimize registration
time and maximize performance in a VLAN environment.
The system value L2QVLAN (initially set to “0”), identifies the 802.1Q VLAN IDentifier. This default
value indicates “priority tagging” as defined in IEEE 802.IQ Section 9.3.2.3, which specifies that the
Ethernet switch in your network closet should automatically insert the default VLAN for the switch port
without changing the user priority of the frame (cf. IEEE 802.1D and 802.1Q).
However, you might not want the default VLAN to be used for voice traffic; for example, you may have
administered a VLAN specifically for IP telephony. In this case, you need to ensure the switch is
configured to allow frames tagged by the 4600 Series IP Telephone through without overwriting or
removing them. In addition, you will want to set the system value L2QVLAN to the VLAN ID
appropriate for your voice LAN.
Another system value you can administer as of Release 1.8 software, is VLANTEST, which stands for
the number of seconds the 4600 IP Series Telephone waits for a DHCPOFFER message when using a
non-zero VLAN ID (the default is “60” seconds). Using this value insures the telephone can return to the
default VLAN if an invalid VLAN ID is administered or if the phone is moved to a port where the value
in L2QVLAN is invalid. The default value is fairly long, to allow for the scenario that a major power
interruption is causing the 4600 Series IP Telephones to restart, but time should be allowed for network
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide

65
Server Administration
Administering Options for the 4600 Series IP Telephones
routers, the DHCP/TFTP Servers, etc. to be returned to service. If the telephone is restarted for whatever
reason and the VLANTEST time limit expires, the telephone assumes the administered VLAN ID is
invalid and re-initiates registration with the default VLAN ID.
Setting VLANTEST to “0” has the special meaning of telling the phone to attempt DHCP using a nonzero VLAN, indefinitely. In other words, the telephone will not return to the default VLAN.
NOTE:
If the telephone has returned to the default VLAN but must be put back on the L2QVLAN
VLAN ID, you need to Reset the telephone according to the procedure in Chapter 3 of the
4600 Series IP Telephone Installation Guide.
The telephone will ignore any VLAN ID administered on the media server if a non-zero
VLAN ID is administered manually, via DHCP, and/or via TFTP.
Administering Options for the 4600 Series IP
Telephones
As indicated in the Introduction on page 37 of this chapter, there are many parameters that can be
administered for the 4600 Series IP Telephones. This section explains how to change parameters via the
DHCP or TFTP servers. In all cases, you will be setting a system parameter in the telephone to a desired
value. Table 6 lists the parameter names, their default values, the valid ranges for those values, and a
description of each one. For DHCP, the parameters below are set to desired values in the DHCP Option,
as discussed in DHCP Generic Setup on page 42 earlier in this chapter. For TFTP, the parameters below
are set to desired values in the TFTP Script File, as discussed in Contents of the Upgrade Script on page
59 also earlier in this chapter.
TFTP Scripts are the recommended way to administer options on the 4600 Series IP Telephones. Some
DHCP applications have limits on the amount of user-specified information; such limits could be
exceeded by the administration required, for example, a 4630 with all applications administered.
You may choose to completely disable the capability to enter or change option settings from the dialpad,
as of Release 1.8. As of that Release, a new system value, PROCPSWD, can be set as part of standard
DHCP/TFTP administration. If PROCPSWD is non-null and consists of 1 to 7 digits, no local procedures
(“dialpad options”) can be invoked unless the user enters the value of PROCPSWD after pressing Mute
or Hold (see “Chapter 3" of the 4600 Series IP Telephone Installation Guide) and before entering the
local procedure code.
NOTE:
Because this password is likely stored on the server “in the clear” and is certainly sent to
the telephone in the clear, you should not consider PROCPSWD as a high-security
technique to inhibit a sophisticated end-user from obtaining access to the local procedures.
Administering this password disables all local procedures, including V I E W, which is
read-only and would not change any settings in any case.

Administering Options for the 4600 Series IP Telephones
DNS Addressing
As of Release 1.5, the 4600 IP Telephones support DNS addresses as well as dotted decimal addresses.
The telephone attempts to resolve a non-ASCII-encoded dotted decimal IP address by checking the
contents of DHCP Option 6, as indicated in DHCP Generic Setup on page 42. At least one address in
Option 6 must be a valid non-zero dotted decimal address - otherwise, DNS will fail. The text string in
the system parameter DOMAIN (Option 15, see Table 6) is appended to the address(es) in Option 6
before the telephone attempts to resolve the DNS address. If Option 6 contains a list of DNS addresses,
they are queried in the order given if no response is received from previous addresses on the list. As an
alternative to administering DNS via DHCP, you may specify the DNS server and/or Domain name in the
TFTP script file (in which case, you should SET the values for DNSSRVR and DOMAIN first; then you
may use those names later in the script).
NOTE:
If Options 6 and 15 are appropriately administered with DNS servers and Domain names
respectively, MCIPADD and TFTPSRVR settings need not be specified in the Site
Specific Option string.
Customizing the Site-Specific Option Number
(SSON)
As discussed in DHCP Generic Setup on page 42, the SSON, defined to be 176 for the 4600 Series IP
Telephones, can be set to a string. For each system parameter listed in Table 6 that you want to include,
append the following to the SSON string:
a comma followed by name=value
where name is a parameter name and value is its associated value. Invalid values will cause the data to be
ignored for that name. Customizing the SSON will affect all telephones associated with that DHCP
server.
Entering Options via the Telephone Dialpad
Chapter 3 of the 4600 Series IP Telephone Installation Guide details how to use the local administrative
options.
To customize any or all of the QoS parameters locally, follow the “QoS Option Setting” procedure in

Enhanced Local Dialing
Enhanced Local Dialing
The 4610SW/4620/4620SW/4630/4630SW IP Telephones have a variety of telephony-related
applications (e.g., Speed Dial, Call Log, Web Browser, etc.) which may obtain a telephone number during
operation. For example, an incoming Call Log call will obtain the Calling Party Number, while the web
browser may obtain a dialable link from a corporate Web site. Before Release 1.8 software, when the user
indicated a desire to call one of these incoming numbers, the 4610SW/4620/4620SW/4630/4630SW
would first require the user to edit the number, generally by prepending digits to account for dial access
codes, country codes if applicable, etc.
As of Release 1.8, the 4610SW/4620/4620SW/4630/4630SW can evaluate a raw telephone number and,
based on administered parameters, automatically prepend the correct digits, saving the user time and
effort. This is the “Enhanced Dialing” feature. The key to this feature’s success is the accurate
administration of several important values. Table 8 summarizes these values and their meanings; that
information is expanded upon here.
NOTE:
In all cases, the values to be administered are the values relevant to the location of the
Avaya media server to which the 4610SW/4620/4620SW/4630/4630SW IP Telephones
are registered. Hence, if the telephone was in Japan, but the media server was in the
United States, the value of PHNCC would be properly set to “1”.
In all cases, the digits inserted and dialed by the 4610SW/4620/4620SW/4630/4630SW
are subject to standard Avaya media server features and administration such as Class of
Service (COS), Class of Restriction (COR), Automatic Route Selection (ARS), etc.
As indicated in Table 6, you can administer the system parameter ENHDIALSTAT to turn
off the Enhanced Local Dialing feature.
The system values relevant to the Enhanced Dialing Feature are:
• PHNCC; the international country code for the media server
(e.g., “1” for the United States, “44” for the United Kingdom, etc.).
• PHNDPLENGTH; the length of the dial plan on the media server.
• PHNIC; the digits dialed from the media server to access public network international trunks
(e.g., “011” for the United States).
• PHNLD; the digit dialed to access public network long distance trunks on the media server.
• PHNLDLENGTH; the maximum length, in digits, of the national telephone number for the
country in which the Avaya media server is located.
• PHNOL; the character(s) dialed to access public network local trunks on the media server.
Example: A corporate voice network has a 4-digit dialing plan. The corporate WML Web site lists a 4digit phone number as a link on the Human Resources page. A 4620 user selects that link, the 4620
deduces the phone number is part of the corporate network (because the phone number’s length is the
same as the corporate dialing plan), and dials the number without further processing.
Example: A user notes the web site displayed contains an international phone number that needs to be
called and presses “Call.” The 4630/4630SW determines the number to be called is from another country
code, and prepends the rest of the phone number with PHNOL (to get an outside line) + PHNIC (to get an
international trunk). The 4630/4630SW then dials normally, with the Avaya media server routing the call
appropriately.

Server Administration
Customizing the 4630/4630SW IP Telephone
NOTE:
The Enhanced Local Dialing algorithm requires that telephone numbers be presented in a
standard format according to how you administer the parameters indicated in Table 8. The
algorithm also assumes that international telephone numbers are identified as such in, for
example, WML Web sites, by preceding them with a plus (+) sign, and with a space or
some non-digit character following the country code.
Customizing the 4630/4630SW IP Telephone
The 4630/4630SW IP Telephone has some unique and powerful capabilities that take advantage of its
large display and access to LAN facilities. If your organization has an LDAP-compliant directory on your
LAN, or if your organization has a corporate Web site suitable for displaying on the 4630’s/4630SW’s
1/4-VGA display, you will need to provide the telephone with key information about the servers that
provide those facilities. Specifically, to administer the 4630/4630SW telephone for the LDAP Directory
application or to administer the 4630/4630SW telephone for the Web Access application, you must
provide the information called for in Table 7, below. This information must be provided in a customized
script file, in accordance with 4600 Series IP Telephone Scripts and Application Files on page 55.
CAUTION:
For the 4630/4630SW to work properly, you must have a 46xxsettings.scr or
46xxsettings.txt file in the same directory as the 4630/4630SW application file. If you do
not edit the 46xxsettings.scr file, the 4630/4630SW will use default settings only. The
46xxsettings file is no longer part of the *zip file on the Avaya software download Web
site, but is available as a standalone download. If you already have such a file because you
downloaded it for a previous release of the 4630, installing the standalone file will
overwrite the original file.
NOTE:
The same 46xxsettings.scr file is used by the 4620 and the 4630/4630SW IP Telephones.
In Table 7, parameters shown with a Mandatory status must be accurate and non-null for the application
to work (however, the Avaya Help Web site will always be available). Parameters with an Optional status
may be changed to suit your environment; if they are not changed, the defaults will be used.

Call Log Archive
Automatic archiving of the Call Log occurs when:
• The Call Log Automatic Archive option setting is Yes and
• The Call Log is more than 50% filled with unarchived entries, or a new (unarchived) log entry
occurs within two hours of the last archive (whichever occurs first).
Call Log Archive automatically saves applicable Call Log entries. When the Call Log Automatic Archive
option on a 4630/4630SW IP Telephone is set to Yes and the FTPSRVR is specified, the FTP APPE
command attempts to save all call log contents to the FTP server (specified by FTPSRVR in the directory
path specified by FTPDIR). Data is saved in a file called 4630calllog.txt. The System Administrator may
optionally specify FTPSRVR and/or FPTDIR via network administration, however, these values may
also be specified by the phone’s user as covered in Chapter 8 of the 4630/4630SW IP Telephone User’s
Guide. Automatic backup occurs whenever the user executes a Save command on a Speed Dial or
Options/Parameter screen.

Telephones” .
The Application Status Flag (APPSTAT)
The 4610SW/4620/4620SW Series IP Telephones offer the user numerous applications like Speed Dial,
Call Log, Redial, etc. Each of these applications lets the user add, delete, or (in some cases) edit entries.
However, you as the administrator may not want the user to have that level of functionality. For example,
a hotel lobby telephone probably should not allow a user to delete the concierge’s Speed Dial number.
Further, for privacy reasons, that same telephone should not allow a Call Log display. The Application
Status Flag, APPSTAT, lets you administer specific application functionality permission levels for one or
more telephones.
APPSTAT consists of one number, specifying a certain level of allowed functionality. Zero (“0”) is the
most limiting setting, “2” and “3” allow increasing levels of functionality, and “1” allows the user
complete application functionality.
Table 9: Application Status Flags and Their Meaning

In Table 9, “suppressed” applications are not displayed to the user. This means softkey labels, application
tabs, etc. that would ordinarily be labeled or displayed to indicate the presence of that application are not
labeled or displayed. Options associated with suppressed applications may continue being displayed

4610SW/4620/4620SW Backup/Restore
(unless overridden by appropriate administration of the OPSTAT parameter), but those options have no
effect while the application is suppressed.
In Table 9, “Speed Dial changes are not allowed” means the Speed Dial application is displayed and can
be used to make calls as normal. However, any user controls that would allow the user to change any
aspect of the Speed Dial application (including the ability to add, delete, or edit any Speed Dial Name or
Number) are not displayed.
In Table 9, “Only one-number Redial is allowed” means the user Option that allows a choice between
displaying one, or three (or six, depending on the telephone) of the last numbers dialed is suppressed, and
only one number is stored in the Redial buffer. The Redial application is not displayed, since only one
number is stored. This restriction allows a certain measure of privacy once a given user has left the
telephone.
Note that you can set APPSTAT to 1 (for example, in a staging area), administer a given telephone with
Speed Dial entries of your choice (such as the Concierge Speed Dial button in our earlier example), then
move the telephone to where it will be used, and where you have administered APPSTAT to be, say, 0
(zero). When that telephone resets, it will retain the Speed Dial entries it had (such as Concierge), but will
not allow the user to create new entries.
When APPSTAT is set to any valid value other than 1, the telephone does not accept any changes to the
Speed Dial button labels that may have been made directly on an FTP backup file. Only the existing
labels in the telephone are used. This restriction prevents circumvention of the APPSTAT restrictions.
APPSTAT has no effect on telephones with no user-selectable applications (such as the 4602). Also, to
“suppress” the WML applications, all you have to do is not administer the appropriate parameters. In
essence, these applications are suppressed by default.
4610SW/4620/4620SW Backup/Restore
Backup/Restore automatically saves a phone’s speed dial button labels and options/parameter settings
(including local Feature Button labels). When the Automatic Backup option on a 4610SW/4620/4620SW
IP Telephone is set to Yes and the FTPSRVR is specified, the FTPSTOR command attempts to save all
Speed Dial contents and all system options and (non-password) parameters to the FTP server (specified
by FTPSRVR). Data is saved in a text file called 4610data.txt or 4620data.txt as appropriate for the
telephone type. The System Administrator may optionally specify FTPSRVR via network
administration, however, these values may also be specified by the phone’s user, as covered in Chapter 6
of the 4620/4620SW IP Telephone User’s Guide or the 4610SW IP Telephone User’s Guide. Automatic
backup occurs whenever the user executes a Save command on a Speed Dial or Options/Parameter
screen.
NOTE:
Users have the ability to specify alternate servers and directories (e.g., their own PCs) for
backup and retrievals.
The 4610SW/4620/4620SW backup/restore file can contain ASCII (and Extended ASCII)
and non-ASCII characters. However, if the file contains non-ASCII characters,
specifically Cyrillic, Katakana, Han, or Hiragana characters, the file must be stored in
UTF-8 form. The 4610SW/4620/4620SW will create a file in this form automatically, but
if you choose to create a backup/restore file yourself, or if you edit this file, you must do
both of the following: 1.) Insert a blank line at the beginning of the file, and 2.) Save the
78
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide
July 2004
Server Administration
4610SW/4620/4620SW Backup/Restore
file in UTF-8 format. These precautions ensure that however your editor stores the data
file, the 4610SW/4620/4620SW will be able to read the contents. If you fail to insert the
blank line, the first line of data may be ignored. The 4610SW and 4620 do not support
display of Cyrillic, Han or Hiragana characters, and even the 4620SW cannot support all
Han or Hiragama characters. If you insert a character that the 4620SW does not support,
that character will be shown as a rectangle on the display.
In addition to Speed Dial labels and associated phone numbers, the following options, settings and nonpassword parameters are saved during a backup:
Setting/Parameter Name
Type
Personalized Ring
Option
Redial
Option
Phone Screen on Answer

Troubleshooting Guidelines
Introduction
This chapter describes problems that may occur during 4600 Series IP Telephone operation and possible
ways of resolving these problems.
Error Conditions
Table 10, Some Error Conditions in Operation of 4600 Series IP Telephones, on page 81 identifies some
of the possible operational problems that might be encountered after successful 4600 Series IP Telephone
installation. Problems that might be encountered during installation, and how to conduct a Self-Test of
the telephone, are discussed in the “Troubleshooting” chapter of the 4600 Series IP Telephone
Installation Guide. The 4601 IP Telephone User’s Guide, 4602/4602SW IP Telephone User’s Guide,
4610SW IP Telephone User’s Guide, 4620/4620SW IP Telephone User’s Guide, and 4630/4630SW IP
Telephone User’s Guide also contain guidance for users having problems with specific 4601,
4602/4602SW, 4610SW, 4620/4620SW and 4630/4630SW applications, respectively.
NOTE:
Most of the problems reported by users of a 4600 Series IP Telephone are not likely to be
problems with the telephone itself. More likely, the problems will be centered on the LAN,
where Quality of Service, server administration, and other issues can impact end-user
perception of IP Telephone performance.
Table 10: Some Error Conditions in Operation of 4600 Series IP Telephones
Condition
Cause/Resolution
The telephone continually reboots, or reboots
continuously about every 15 minutes.
CAUSE: This is a firmware fault; the MAC address in
memory is corrupted.
RESOLUTION: The telephone must be returned to
Avaya for repair.
The message light on the telephone turns on and off
intermittently, but the telephone never registers.
CAUSE: This is a hardware fault.
RESOLUTION: The telephone must be returned to
Avaya for repair.

Condition
The telephone stops
working in the middle of
a call,
The telephone had been
working, but does not
work now,
82
Cause/Resolution
AND no lights are lit on
the phone and the display
is not lit.
CAUSE: Loss of power
AND power to the
telephone is fine (and the
telephone may have gone
through the restarting
sequence).
CAUSE: Loss of path to Avaya media server, DHCP
Lease expired, or DHCP server not available when
telephone attempts to renegotiate DHCP lease.
RESOLUTION: Check the connections between the
telephone, the power supply, and the power jack. For
example, verify that either static addressing was not used
or that any changes to static addresses were entered
correctly.
RESOLUTION: As above. Note that if the telephone is
attached to a 30A switched hub, upon loss of Ethernet
connectivity, the usual No Ethernet message is not
displayed.
AND no lights are lit on
the phone and the display
is not lit.
CAUSE: Loss of power.
AND power to the
telephone is fine, but
there is no dialtone.
(Display might show
“System Busy”.)
CAUSE: Loss of communication with the PBX switch
AND the telephone was
recently moved.
CAUSE: Loss of communication with the PBX.
AND the network was
recently changed (servers
upgraded or replaced,
your Avaya media server
is re-administered, NAT
has been added or
changed, etc.).
CAUSE: Loss of communication with the PBX.
RESOLUTION: Check the connections between the
telephone, the power supply, and the power jack.
RESOLUTION: Check LAN continuity from the PBX
to the telephone (using ARP or trace-route) and from the
telephone to the PBX (by invoking a feature button).
Verify the LAN administration has not changed for the
Gatekeeper or TN 2302AP boards or the LAN equipment
(routers, servers, etc.) between the switch and the
telephone. Verify no one has locally changed the
telephone settings (by using the VIEW and ADDR
codes, as described in the 4600 Series IP Telephone
Installation Guide). Verify the volume on the telephone
is set high enough. Finally, conduct a self-test.
RESOLUTION: As above, but pay particular attention
to the possibility that the telephone is being routed to a
different DHCP server, or even a different PBX switch. If
so, the new server or switch may need to be administered
to support the telephone.
RESOLUTION: As above.

Error Conditions
Table 10: Some Error Conditions in Operation of 4600 Series IP Telephones Continued
Condition
The telephone works, but
the audio quality is poor,
specifically:
Cause/Resolution
the user hears echo when
speaking on a handset.
CAUSE: Echo from digital-to-analog conversion on your
Avaya media server trunk.
RESOLUTION: Verify which trunk is causing the echo,
and swap the trunk’s Trunk Termination parameter on the
PBX.
the user hears echo on a
headset, but not on a
handset.
CAUSE: Improper headset adapter.
the user is on
speakerphone and hears
no echo, but the far end
hears echo.
CAUSE: Room acoustics
the user experiences
sudden silences (gaps in
speech), static, clipped or
garbled speech, etc.
CAUSE: Jitter, delay, dropped packets, etc.
RESOLUTION: Replace adapter with Avaya’s M12LU
or 3412-HIC adapters. The M12LU is recommended,
since it supports Automatic Gain Control.
RESOLUTION: Ensure there are six inches or so of
blank space to the right of the telephone. If that is
insufficient, use the handset.
RESOLUTION: One or more Quality of Service (QoS)
features should be implemented in the network (See
Chapter 3 of the 4600 Series IP Telephone Installation
Guide).
CAUSE: Improper (non-Category 5) wiring.
RESOLUTION: Replace non-Category 5 wiring with
Category 5 wiring.
The 4612 or 4624 IP Telephone works properly
except the phone does not ring.
CAUSE: The Ringer Off (RngOF) softkey feature has
been activated.
RESOLUTION: Use the softkey Menu option to access
the RngOF feature. A downward-pointing triangle
means the Ringer is off. Ensure the triangle points up.
Also, check the Volume setting on the telephone. Finally,
do a Self-test on the telephone.
The telephone works properly except for the speaker.
CAUSE: The Speaker was turned off on the PBX.
RESOLUTION: Administer the PBX to allow that
station’s speaker to operate. If that does not work, do a
Self-test on the telephone.
The telephone works properly, except incoming
DTMF tones are not received.
CAUSE: The TN2302AP board does not pass in-band
DTMF tones.
RESOLUTION: None; the board is operating as
designed.

Troubleshooting Guidelines
Error Conditions
Table 10: Some Error Conditions in Operation of 4600 Series IP Telephones Continued
Condition
Cause/Resolution
The telephone works properly, except sidetone DTMF
is not heard.
CAUSE: PBX suppresses sidetone DTMF.
Hands-Free Answer (HFA) is administered but the
telephone did not automatically answer a call.
RESOLUTION: On PBX administration, on the
Change-System-Parameters screen, enable On-Hook
Dialing. If the user has Hands-Free Answer (HFA) and
answers the call on the telephone’s speakerphone, then
switches to the handset, pressing the dialpad buttons does
not send DTMF tones. This is a known bug, and the only
current resolution is to disable HFA.
CAUSE: HFA only works if the telephone is idle. If a
second call comes into the telephone while the first call is
in progress (including ringing before the first call is
answered), the second call is ignored.
RESOLUTION: None.
The TFTP application terminates and asks for
registration.
CAUSE: Non-Avaya shareware or freeware TFTP
applications often cease operating to request registration.
RESOLUTION:
Short-term: Restart the application.
Long-term: Register the product or replace it with an
application that does not behave this way (for example,
Avaya’s TFTP application).
The TFTP script file is
ignored or not used by
the telephone
AND the TFTP server is
a LINUX or UNIX
system.
CAUSE: The telephone expects lines of the script file to
terminate with a <Carriage Return> <Line Feed>.
Some UNIX applications only terminate lines with
<Line Feed>. Editing the script file with a UNIX-based
editor can strip <Carriage Return>s from the file,
causing the entire file to be treated as a comment, and
thus be ignored.
RESOLUTION: Edit the script file with a Windows®based editor, or another editor that does not strip out the
<Carriage Return>.
CAUSE: UNIX and LINUX systems use case-sensitive
addressing and file labels.
RESOLUTION: Verify the file names and path in the
script file are accurately specified.
AND telephone
administration was
recently changed.
Power to the telephone is interrupted while the
telephone is saving the application file and the TFTP
application hangs.
84
CAUSE: The 46xxupgrade.scr file was mis-edited,
renamed, etc.
RESOLUTION: Download a clean copy of the
46xxupgrade.scr file from the Avaya Support Web site,
and do not edit or rename it. Make any customization
changes only to the 46xxsettings file, as discussed in
Chapter 4, “Server Administration”.
CAUSE: The TFTP server hangs if power is interrupted
while a telephone is saving the application file.
RESOLUTION: Restart the TFTP server.

Troubleshooting Guidelines
Error Conditions
Table 10: Some Error Conditions in Operation of 4600 Series IP Telephones Continued
Condition
Cause/Resolution
The DHCP server indicates the 4600 Series IP
Telephone reports itself as a Token Ring device, and
refuses to provide the telephone an address.
CAUSE: Early versions of the 4600 Series IP
Telephones erroneously report being a Token Ring
device. With most DHCP servers, this does not matter.
Some LINUX servers, however, will refuse to issue
addresses to Ethernet devices reporting to be Token Ring
devices.
RESOLUTION: Administer the DHCP server to delete
all MAC and IP addresses associated with Lucent
Technologies or Avaya, or allow the associated DHCP
leases to expire.
The user indicates a 4610SW/4620/4620SW-specific
or 4630/4630SW-specific application is not
accessible.
CAUSE: The 46xxsettings script file is not pointed to
accurately, or is not properly administered to allow the
application.
RESOLUTION: Assuming the user is meant to have
that application, verify the 46xxsettings script file is
properly specified for your system, including case (if
your TFTP server is UNIX or LINUX) and extension.
Then, verify all the relevant parameters (as indicated in
Table 7, 4630/4630SW IP Telephone Customizable
System Parameters by Application, on page 71 and Table
8, 4610SW/4620/4620SW IP Telephone Customizable
System Parameters, on page 76, as appropriate) are
accurately specified in the 46xxsettings file.
There are three areas where installers can troubleshoot problems before seeking assistance from the
system or LAN administrator:
1
Check the wiring (power and Ethernet) for the following:
• Whether all components are plugged in correctly.
• Check LAN connectivity in both directions to all servers (DHCP, TFTP, media server).
Note that if the telephone is attached to a 30A switched hub, upon loss of Ethernet
connectivity the usual No Ethernet message is not displayed.
• If the telephone is supposed to be powered from the LAN, ensure the LAN is properly
administered and is compliant with IEEE 802.3af-2003.
2
If you are using static addressing, do the following:
• Use the VIEW command to find the names of the files being used and verify that these
filenames match those on the TFTP server. Check on the Avaya Web site to verify whether
the correct files are being used. Note that the 4601 IP Telephone does not support static
addressing and therefore, does not support the VIEW command.
• Use the ADDR option to verify IP addresses.
• Use the QoS option to verify QoS parameters.
Refer to Chapter 3 of the 4600 Series IP Telephone Installation Guide.
3
If the 4600 Series IP Telephone is not communicating with the system (DHCP, TFTP, or media
server), make a note of the last message that was displayed and consult the system administrator.

The Clear Administrative Option
The Clear Administrative Option
Sometimes, you may want to remove all administered values, user-specified data, and option settings,
etc. Essentially, you want to return a telephone to its initial “clean slate” condition. Typically, this is done
when passing a telephone to a new, dedicated user when the user’s L O G O F F option is not sufficient
(for example, the new user has the same extension, but should have different permissions than the
previous user). The C L E A R option erases all administered data—static programming, file server and
call server programming, and user settings (including Speed Dial button labels and locally-programmed
Feature Button labels) and restores all such data to default values. The C L E A R option does not affect
the software load itself, so if you have upgraded the telephone, the phone retains the latest software. Once
a telephone has been Cleared, you can administer it normally.
CAUTION:
This procedure erases all administered data, without any possibility of recovering the data.
NOTE:
The CLEAR Administrative Option is supported only on telephones with Release 2.1 or
later software.
Use the following procedure to clear the phone of its administrative, user-assigned and options values.
1
While the phone is on-hook and idle, press the following sequence of keys on the faceplate of the
telephone:
Mute 2 5 3 2 7 # (Mute C L E A R #)
NOTE:
Press the Mute button momentarily. Do not press this button while pressing other
keys/buttons. The 4630/4630SW IP Telephones and the 4690 IP Conference Telephone do
not have a dedicated Hold button; for all other 4600 Series IP Telephones, pressing the
Hold button instead of the Mute button also works.
The following text displays left-justified at the top of the display:
Clear all values?
*=no
#=yes
2
If you do not want to clear all values, press * (no) to terminate the procedure and retain the current
values.
A screen displays the following prompt on the top line:
Are you sure?

3
Press the * button to terminate the procedure without clearing the values. Press the # button to
clear all values to their initial default values.
A confirmation tone sounds and the following text displays left-justified at the top of the display:
Clearing values.
The telephone is cleared to its “out of the box” state.

The Reset Administrative Option
The Reset Administrative Option
As indicated in some troubleshooting procedures, sometimes it is appropriate to reset the 4600 Series IP
Telephone. Procedures on how to do so are printed below, and can also be found in Chapter 3 of the 4600
Series IP Telephone Installation Guide. The following is the list of parameters, settings, etc., that are reset
to default values (including “null” as applicable) when the Reset procedure is completed:
• Registration extension and password.
• All values administered by local procedures, in accordance with Chapter 3 of the 4600 Series IP
Telephone Installation Guide.
• All values previously downloaded via DHCP or from a TFTP settings file (although, of course,
these values are generally restored when the telephone goes through registration again after the
reset).
NOTE:
If PROCSTAT was administered to 1, as described in Chapter 4, “Server
Administration”, you will not be able to invoke the R E S E T option. In addition, if
PROCPSWD was administered as non-null, you must enter that value after you press
Mute and before you press R E S E T.
Reset System Values
Use the following procedure to reset all system initialization values to the application software default
values.
CAUTION:
This procedure erases all static information, without any possibility of recovering the data.

RESOLUTION: If this message appears for more than a few seconds, especially if
the IP Address keeps changing, the telephone is unable to contact the Gatekeeper.
Verify network connectivity between the telephone and the Gatekeeper, or revise
the Gatekeeper addresses in the DHCP/TFTP files (see Administering 4600 Series
IP Telephones on Avaya Media Servers, DHCP, and TFTP) to point to different
Gatekeepers.
Discovering...
CAUSE: The telephone is seeking a gatekeeper on the media server, using its
administered gatekeeper list.
RESOLUTION: Wait for a valid registration to occur, or press # to interrupt the
search and re-initialize manual or DHCP/TFTP procedures.
File too large
CAUSE: The telephone does not have sufficient room to store the downloaded file.
Cannot save file
RESOLUTION: Verify the proper filename is administered in the TFTP script file,
and that the proper application file is located in the appropriate location on the
TFTP server.
Gateway Error
CAUSE: DEFINITY Release 8.4 does not have an H.323 station extension for this
telephone.
RESOLUTION: On the station administration screen, ensure the DCP set being
aliased for this IP telephone has an H.323 station extension administered, in
accordance with switch administration instructions.
Hardware failure
CAUSE: Hardware failure prevented downloading of application file,
RESOLUTION: Replace telephone.
IP Address in use by
another
CAUSE: The telephone has detected an IP address conflict.
NAPT Error
CAUSE: A device between the telephone and the call server is invoking Network
Address Port Translation, which the 4600 Series IP Telephones do not support.
RESOLUTION: Verify administration to identify duplicate IP address(es).
RESOLUTION: Remove or re-administer the NAPT device or move the
telephone.
No Ethernet
CAUSE: When first plugged in, the IP Telephone is unable to communicate with
the Ethernet.
RESOLUTION: Verify the connection to the Ethernet jack, verify the jack is
Category 5, etc. Note that if the telephone is attached to a 30A switched hub, upon
loss of Ethernet connectivity, the usual “No Ethernet” message is not displayed.
No file server
address
92
CAUSE: The TFTP server IP address in the IP telephone’s memory is all zeroes.
RESOLUTION: Depending on the specific requirements of your network, this
may not be an error. If appropriate, either administer the DHCP server with the
proper address of the TFTP server, or administer the telephone locally using the
ADDR option as detailed in the 4600 Series IP Telephone Installation Guide.

VISUAL INDICATION: If the extension is currently being used and a first registration
attempt is made, the Message Waiting indicators at the top of phone and left middle of the
faceplate display a broken flutter (alternating 50 milliseconds on, 50 milliseconds off for
500 milliseconds followed by 500 milliseconds off) five times, then flash continuously,
awaiting user entry. If a second registration attempt is made using the same extension, the
Message Waiting indicators at the top of phone and left middle of the faceplate display a
continuous broken flutter (alternating 50 milliseconds on, 50 milliseconds off for 500
milliseconds followed by 500 milliseconds off). In addition, Call Appearance Line b’s LED
flashes continuously until either the “*” or “#” button is pressed.
CAUSE: The PBX detects an extension conflict with an existing set or Softphone.
RESOLUTION: You can force the current telephone to register, and thereby disconnect
the other user, by pressing #. The 4600 Series IP Telephone prompts you again for the
Extension and Password. If you enter the same Extension and Password, you must confirm
that you want to unregister the original user. Press # to unregister the original user and
register the current phone; then press * to reset the phone and enter a different Extension

Creating Web sites for the
4630/4630SW IP Telephone
Introduction
This Appendix describes the capabilities and limitations of the web browser in the 4630/4630SW IP
Telephone and provides suggestions for designing Web sites for viewing on the 4630/4630SW. It is
intended for 4630/4630SW IP Telephone Web Browser [web page] designers, and assumes readers are
familiar with HTML, Style Sheets, and ECMAScript.
This Appendix serves two primary functions. It:
• Presents the technologies that have been implemented in the 4630/4630SW IP Telephone Web
Access application, including any limitations or non-standard implementations, and
• Provides a suggested model for developing effective web pages to be viewed in the browser.
This Appendix is not intended to provide technical details on setting up a web server, nor does it provide
information on web server technologies. Finally, this document is not intended to provide an introduction
to web browser protocols or technologies.
NOTE:
A link to sites where HTML templates are available for customizing can be found on the
Avaya Web site.
Any subsequent reference to the 4630 IP Telephone in this Appendix applies equally to the
4630SW IP Telephone.
General Background
The 4630 IP Telephone display is a quarter VGA (320 pixels wide by 240 pixels high, 256 colors
supported) display.
The data types and other features supported in the browser include:
•

Browser Features and Behavior
Browser Features and Behavior
This section presents the technologies that have been implemented in the 4630 IP Telephone Web Access
application, along with any limitations or non-standard implementations. Since style sheets have become
the preferred mechanism for controlling web page appearance and have made obsolete most attribute
specifications with tags, the majority of attributes for tags were not tried. The attributes that were tested
were those of real interest to specific tags. The browser is HTML 4.0 compliant, with a few minor
differences as noted below.
NOTE:
In the sub-sections that follow, comments specific to the 4630 IP Telephone and its
browser are shown in italics.
Document Skeleton
Certain tags define the basic framework of an HTML document. While most browsers are normally good
at dealing with missing tags, when style sheets are applied it is essential that the tag structures be
followed. Even ignoring style sheets, it is considered good style to follow the HTML rules. The following
tags make up the basic skeleton of an HTML document:
• <html> indicates the start of an HTML document.
• <head> indicates the start of an HTML document’s header. Title, meta definitions, ECMAScript
function definition, document level style sheet definition, and external style sheet inclusion are all
done in the header section.
• <title> sets the title of the document. Normally this is shown in the frame of the browser window.
On the phone, the title is shown in the Top Line Information Display Area.
• <body> indicates the start of the body of an HTML document. The rest of the document will be
embedded between the start and end <body> tags.
• <meta> is used to add additional information about an HTML page. This is typically used by web
walking tools, is of little use in browsers, and has no effect on the phone.
Content-Based Style
Content-based tags deal with identifying words, phrases or chunks of text, or images as having a specific
meaning or context. The intent of content-based tags is not to show physically marked text. However, it is
not wrong for a browser to show content-based text in a distinct style, such as font style.
Each content-based tag is shown with a brief description, and any physical effects imposed by the
browser.

<abbr> indicates an abbreviation. Using this tag has no effect.
<address> indicates an address. Using this tag has no effect.
<acronym> indicates an acronym. The enclosed text is shown in an italic font.
<cite> indicates a bibliographic citation or reference. The enclosed text is shown in an italic font.
<code> indicates source code of a program. The enclosed text is shown in a monospaced font.
<del> indicates deleted text. It is intended to show editorial markup. The enclosed text is shown
with a line through it.
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide
July 2004
Creating Web sites for the 4630/4630SW IP Telephone
Browser Features and Behavior
• <dfn> indicates a definition for a term. This is normally used with the first appearance of a term in
a document. The enclosed text is shown in an italic font.
• <em> indicates emphasis on a string of text. This is the contextual equivalent of using the <i>
(italic) tag. The enclosed text is shown in an italic font.
• <ins> indicates inserted text. It is intended to show editorial markup. The enclosed text is shown
underlined.
• <kbd> indicates keyboard input. This is similar to the <code> tag, but with a different contextual
intent. The enclosed text is shown in a monospaced font.
• <samp> indicates literal text. The enclosed text is shown in a monospaced font.
• <strong> indicates emphasis on some text, but in a stronger contextual sense than the <em> tag.
This is the contextual equivalent of using the <b> (bold) tag. The enclosed text is shown in a bold
font.
• <var> indicates source code variables. This is similar to the <code> tag, but with a different
contextual intent. The enclosed text is shown in an italic font.
Logical Style
Tags that control logical style provide a similar functionality to those that control content-based style, but
they have no implicit visual characteristics or contextual meaning. Instead, they only provide a means of
invoking a style sheet. These tags, like all others, may have an ID and class attribute set. Using style sheet
rules for these class names and IDs allows the designer to provide decoration, font, and color styles to
each section. Thus, these tags may be considered to be designer-defined content-based tags:
• <div> indicates a division. A newline is inserted between the previous text and the text following
the <div> tag. No physical changes are noticeable, except those implemented in style sheets.
• <span> indicates a spanned section of text is placed immediately after the text preceding the tag
with a newline. No physical changes are noticeable, except those implemented in style sheets.
Physical Style
Physical tags are effectively the opposite of content-based tags. The text in a physical tag may have no
meaning whatsoever, outside of what the designer intended. These tags show text in a distinct style.
Physical tags typically affect font style.
Each physical style tag is shown below with a brief description, and any physical effects imposed by the
browser.
•
•
•
•
•
<b> indicates that the text should appear in a bold font weight.
<big> indicates that the text should appear one point size larger than the current text.
<i> indicates that the text should appear in an italic font.
<small> indicates that the text should appear one point size smaller than the current text.
<sub> indicates that the text should appear as a subscript to the current text. The text is shown one
point size smaller.
• <sup> indicates that the text should appear as a superscript to the current text. The text is shown
one point size smaller.
• <tt> indicates that the text should appear as teletype text. The text is shown in a monospaced
typeface font.

Browser Features and Behavior
Physical Spacing and Layout
Physical spacing and layout tags define the basic structure of a document. Headings, paragraphs, tables
and lists all provide some basic physical and logical layout to a page.
Each spacing and layout tag is shown with a brief description, and any unusual behavior is described.
• <p> indicates the start of a new paragraph. A blank line is inserted between previous text and text
following the <p> tag.
• <br> indicates that a breakpoint should be inserted. A newline is inserted between previous text
and text following the <br> tag.
• <pre> indicates that the following text should have no formatting rules applied to it. This implies
that no wrapping will be applied to this text, which may result in a horizontal scrollbar being
added to view the text.
• <hr> indicates that a newline and a horizontal rule (line) should be inserted between the previous
text and text following the <hr> tag.
• <blockquote> indicates that the following text is a quote, and should be offset in some way. The
embedded text is shown with newlines before and after the text, and spacing to the left and right.
Within that “block” of text, normal wrapping rules are applied.
• <q> indicates that the following text is a short quote, and should be shown in double-quotes
(according to documentation). This text appears as normal text, with no physical identifying
indications.
• <h1> - <h6> indicate heading sections. Each level is one point smaller than the previous level,
with <h1> being the largest.
The section titled Maintaining Context on page 111 contains design guidelines for maintaining user
context.
Lists and Tables
For presentation of data in a logical format, lists and tables are two of the more important sets of tags.
Since space is at a premium in the browser, tables should be used with discretion. While they provide sets
of text, which are easy for the eye to process, they can quickly become cumbersome if misused in this
browser. Both width and height are limited, so the data provided in the table cells should be short pieces
of text. Beyond that, the page designer should come up with a different model for presenting the data,
possibly using lists and divisions.
Lists
• <ol> starts an ordered list. This provides a list with some type of numbering: upper-case letters,
lower-case letters, digits, upper-case roman numerals, lower-case roman numerals. Setting the
type attribute is ignored in the browser.
• <ul> starts an unordered list. This provides a list with bullets to the left of each item.
• <li> adds an item to an ordered or unordered list.
• <dl> starts a definition list. This is a list with two fields per list item. The first is a term and the
second is the term’s definition.
• <dt> adds a new definition term to a definition list.
• <dd> adds a new term definition to a definition list.

Creating Web sites for the 4630/4630SW IP Telephone
Browser Features and Behavior
Tables
The new HTML 4.0 table tags, <thead>, <tbody> and <tfoot> are all implemented. These tags are
intended primarily to allow printed pages to have headers and footers appear on each page, when the table
is longer than a single page. Since the 4630 IP Telephone Web Browser does not provide the ability to
print, it is recommended that these tags not be used.
• <table> starts a table layout.
• <caption> adds a caption to a table. The align attribute allows a caption to be placed above or
below the table. This attribute has no effect in the phone.
•
•
•
•
<tr> adds a new table row to a table.
<th> adds a header for some column(s) of a table.
<td> adds a piece of data for some row(s) and column(s) of a table.
<thead> defines a set of table header rows. The intent of this tag is to provide a set of header rows
for each printed page. While viewing the page in a browser, the header has no more effect than the
<th> tag. What it does provide for the designer is a more logical breakout of the data. It is easy to
recognize the header area of the table since it is set between the <thead> start and end tags.
• <tbody> defines the main body of a table, when used in conjunction with the <thead> and <tfoot>
tags.
• <tfoot> defines a footer for a table. This tag may contain multiple rows. Like the <thead> tag, the
intent of this tag is to provide a set of footer rows for each printed page. Viewing the page in a
browser has no additional effect. And like the <thead> tag, this tag provides a logical breakout of
the data for the designer.
• <colgroup> defines a column group. It may be used as a single definition of identical columns or
as a container for dissimilar columns. The span attribute defines what columns are parts of each
group.
• <col> controls the appearance of one or more columns within a column group.
Images
The 4630 IP Telephone Web Browser handles both GIF and JPEG image formats. No other image
formats, included animated GIFs, are supported. Note that images take up a large amount of memory
(compared to text) and updating the display can be an issue; therefore, it is recommended that images be
kept to a minimum.
The image tags that may be used on the browser are as follows:
• <img> displays an image.
• <map> display a client-side image. Client-side images have shaped regions called areas. These
areas are tied to URLs or ECMAScript functions. When an area in a region is clicked, the
ECMAScript function is executed.
• <area> defines an area in a <map> image. Each area uses the href attribute to define a URL to
jump to, or some ECMAScript to execute, when the mouse is clicked on that area.
See the Design Guidelines on page 108 for information on displaying images.

value of the HREF attribute for a given link is of the form tel:nnnnn or javascript:dial(‘nnnnn’), when
that link is selected, the characters nnnnn are passed to the 4630/4630SW Phone application for direct
dialing.
Hyperlinks are the heart of the web browser’s power. The link is what allows the user to click on some
text or an image to jump to another web site, another page within this site, or another area in this page.
Although URLs allow various protocols to be used, only http and https should be used for the 4630 IP
Telephone Web Browser.
• <a> specifies the full or relative URL for a hyperlink. When using the target attribute, the _blank
name should never be used. With the exception of frames, the 4630 IP Telephone Web Browser is
not intended to be a multi-window browser. Thus, if a page attempts to reference a new, nonframe window, the browser will become confused and a reboot will be necessary.
• <base> defines the default target to be used in all <a> tags. This is done by setting the target
attribute of the <base> tag. If the target attribute has been set in the <a> tag, the <base> tag value
is ignored.
The use of the target attribute with the Web Access Application is strongly discouraged because the
application supports a single window for browsing. The use of the target attribute may cause the browser
software to create a new window that is outside of the Web Access Application’s control.
Frames
Frames allow multiple windows to be created on the browser’s base window. The browser is effectively
split up into multiple areas. Each frame may be given a name or ID. Using the target attribute of the <a>
tag, a web page may be displayed in another frame.
Although frames behave as defined, the small size of the screen makes them impractical to use. Just like
tables, frames take up too much room on the display. One could, though, take advantage of frames by
having a small “table of contents” frame with images for links. In general, however, use of frames is
strongly discouraged.
•
•
•
•
<frameset> defines an area for a set of frames.
<frame> defines a single frame in a frameset.
<iframe> defines an in-line frame. More detail
<noframes> provides a fallback for browsers that don’t handle frames. If the designer intends to
use frames and make these pages available to phone, this tag should certainly be employed.
See the Design Guidelines on page 108 for information on displaying frames.

Browser Features and Behavior
Forms
HTML forms provide the user the ability to enter data into a web browser. This data can then be passed
on the web server for processing. It is difficult to predict what web designers might have in mind for the
4630 IP Telephone Web Browser. However, all forms-related tags have been verified, and the results are
presented here.
• <form> defines the basic input form, and defines the action to be performed when the submit
button is selected, via the action attribute.
• <input> defines most user input. The type attribute defines the type of input to be used. The
<button> tag was created to replace type values of button, reset and submit, in a cleaner, more
flexible way. Other type values available are checkbox, hidden, image, password, radio, and text.
The type value file is useless in the context of this browser, since the intent of this control is to
allow the user to select a file on their local disk.
• <button> defines a button that the user may select. This behaves much like the <input
type=button> tag, except that the physical appearance is three-dimensional and any text, image, or
combination, may be displayed in the button.
• <fieldset> encapsulates a section of a form’s contents to create a group of related form controls.
The phone’s browser puts a simple box around the fieldset.
• <label> associates a relationship between a form control and one or more text labels. Labels may
be tied to form controls by the for attribute in the label and the id attribute in the form control.
They may also be tied by embedding the form control inside the <label> tag (for example,
<label>Name: <input type=text id=name></label>).
• ·
<legend> gives a label to a <fieldset> tag. This label appears at the top of the
fieldset section of the form, with a line separating the legend from the rest of the fieldset.
•
•
•
•
<optgroup> provides nested, cascading menus to the user. This doesn’t seem to work.
<option> defines the values available in a <select> scrolling list or drop-down menu.
<select> defines scrolling lists and drop-down menus.
<textarea> provides free-form user input and display. This provides a scrolled text area for the
user to read or type text.
Character Entities
As with any syntactic language, HTML has certain characters that have special meaning. The two most
obvious of these characters are the < and > symbols, which surround all tags. These characters cannot be
typed in directly if the designer’s intent is to display these characters. Thus, all characters that can be
displayed in a web browser have numeric values assigned to them. In addition, many of these characters
have names also assigned. The numeric values are entered into the source web page as &#nnn; where nnn
is some 3 digit value. For example, the < symbol is entered as ’&#060;’. Name values are entered into the
source web page as &name; where name is the name associated with this character. Again, using the <
symbol, this would be entered as ’&lt;’. The set of characters defined by the World Wide Web Consortium
are fully supported in the browser in conformance with the standard.

Design Guidelines
Colors
The browser supports 256 colors. Colors may be specified by name, RGB percentages or RGB raw
numbers. The HTML and CSS specifications suggest 16 named colors. The 4630 IP Telephone browser
recognizes these color names, which are: aqua, black, blue, fuchsia, gray, green, lime, maroon, navy,
olive, purple, red, silver, teal, white, and yellow. Beyond these 16 well-known names, it is recommended
that RGB percentages or raw numbers be used for specifying colors.
Fonts
Font specifications are one of the most important styles that may be applied to a web browser. Because of
the size of the screen on the 4630 IP Telephone, the browser has only a single font available for use. Font
weights, such as normal and bold, are supported, although finer values, such as lighter and bolder are not.
Normal and Italic font styles are also supported. Font sizes are also supported, specified by either
percentages or raw numbers can be used. However, percentages below 50% all appear as the same size.
Although some problems were found with font specifications, given the size and resolution of the screen,
fonts behave reasonably well. The only major problem found is the inability to specify font families.
See the Design Guidelines on page 108 for information on displaying images.
Cookies
Cookies can be a useful feature in maintaining the state of a user when interacting with a web site. HTTP
provides no state information, such as when or how often a user has visited a site. Cookies allow web
sites to track this information by storing a simple set of values on the browser for the current session.
Normally, browsers also provide the ability to save cookies to disk, so this information may be retained
between sessions. However, the 4630 IP Telephone browser has no such ability to save any data between
sessions. Cookies do behave well within the realm of the current session, and may be employed if
desired. The 4630 IP Telephone has a maximum of 8Kilobytes of data available for cookie storage.
Design Guidelines
This section presents guidelines for developing a good model that effectively presents web pages to be
viewed on the 4630 IP Telephone Browser. The biggest challenge in designing pages for this browser is
the limited amount of space available for viewing the pages. The 4630 IP Telephone screen is a ¼ VGA
display. Part of that screen is lost to the browser by the main controls of the 4630 IP Telephone. Thus,
page layout must be done effectively and efficiently so as to avoid causing more space to be lost through
additional screen controls such as scrollbars. Font sizing will make or break the usability of a page. A
balance must be found between fitting as much text as is possible, and allowing users to read the text
without straining their eyes.
108
4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide
July 2004
Creating Web sites for the 4630/4630SW IP Telephone
Design Guidelines
Fixed-Width Objects
One of the primary functions of a web browser is to present text, wrapped at the right (or left when
dealing with internationalization) border of the browser window. The browser always attempts to avoid
adding a horizontal scrollbar. However, if fixed-width objects, such as tables and pre-formatted (<pre>
tags) text are used, the browser makes wrapping a secondary priority to presenting the data exactly as the
HTML dictated.
Web browsers do not resize themselves larger when scrollbars are added. Thus, if there are more lines of
text than can fit in the height of the browser window, a vertical scrollbar is added. This now takes up
some of the width of the browser, and less text displays on a single line. If text is wider than the width of
the browser, a horizontal scrollbar is added. This now takes up some of the height of the browser, and
fewer lines of text are displayed.
Given the small size of the browser, it is highly desirable to avoid causing scrollbars to appear. Unless the
amount of text shown in a page is kept to a bare minimum, it is unlikely that a vertical scrollbar will be
avoided. However, avoiding fixed-width objects, or ensuring that the size of fixed-width is kept small,
will gain some viewable space on the browser.
In general, if scrolling is a requirement, vertical scrolling is better perceived by users than horizontal
scrolling.
Images
The use of images in a web page is always a concern. For example, a page with many images can cause
downloading to be slow. While this is still a concern in the phone, the size of an image has a much greater
effect. Memory in the browser, and in the phone in general, is limited. Each image will use a sizable
amount of memory, and the browser may become overwhelmed. An image should only be used if it is
essential to a page.
Images also fall into the realm of fixed-width objects. All images should be checked to verify that they
don’t cause a horizontal scrollbar to be added. An image may be scaled down by the browser, by setting
the width and height attributes of the <img> tag. The designer may instead choose to scale the images
when setting up the web site. This avoids forcing the browser to deal with the sizing (using the width and
height attributes scales the image after it is downloaded by the browser) and speeds up downloading of
the images. Finally, reducing the size of the image reduces the amount of memory used.
Animated GIF images are a bad idea since they use up quite a bit of memory. Additionally, because of the
persistence of the LCD screen, animated images tend to smear in the browser and lose their effectiveness.
Hence, animated GIFs are considered “not supported” with this phone.

Creating Web sites for the 4630/4630SW IP Telephone
Design Guidelines
Frames
While frames provide a useful method of browsing a series of pages (via a contents frame and a
document text frame), they also use up real estate, just like scrollbars. Even if the frame decorations were
all turned off, the frame containing the majority of the document text now suffers the problems discussed
above; the width of the frame is smaller, and the chances of adding a horizontal scrollbar have increased.
Additionally, a single line of text will have fewer characters viewable, and the page becomes even more
difficult to read and comprehend. Using simple navigation buttons at the top and bottom of the page, or
even at the top and bottom of each section should make up for the missing contents frame.
The interaction between frames and scrollbars is another important area of concern. While most browsers
manage scrolling within each frame independently, the 4630 Web Access Application only scrolls the
entire (single) window. This moves the user’s view of the frames as a whole, but it does not scroll any of
the data in individual frames. There will likely be data in frames that can never be seen.
The combined problems of minimal screen real estate and the scrolling issues really makes frames
something simply to avoid.
Fonts
Font size is a major concern in the browser. Without designer intervention, the browser displays text as if
it were running on a PC in a normal width and height display. This means that the fonts shown would
appear huge relative to the screen size. As a result, only seven lines of text will be viewed in the browser
when no font sizing is applied. Additionally, only about 25 characters would be viewed per line. This
would generally be unusable from a practical point of view.
To make the browser usable, some form of font sizing should be performed to allow a reasonable amount
of text to be viewed on one screen. Ideally, font sizing should be done in a single external style sheet, and
all pages should reference this style sheet. Setting font sizes in document-level style sheets, or even
worse, in in-line style sheets or <font> tags, makes it very difficult for the designer to update font
changes, and runs the risk of failing to make the change everywhere. By using a single external style
sheet, consistency in the pages is managed.
Defining fonts may be done in a static external style sheet or by dynamically generating a style sheet
using some form of server-side application, such as a CGI script or a Java servlet. Using dynamic
generation of a style sheet allows the server to decide, per user, what font size to use. This in turn allows
the user to notify the server to change the font size. All HTML pages would have an external style sheet
reference, which is another server-side executable. This executable would dynamically generate font
information based on the cookie, form component or configuration value, relative to the IP address of the
phone. Using a static external style sheet makes page development and testing much easier, since how it
appears to the designer would be how it appears to the reader. Allowing the user to choose a font size
forces more work on the designer to verify that all fixed size items appear acceptably

Design Guidelines
Maintaining Context
Given the small working area, it is easy for the user to become lost. Headings will often not be in view,
and the user, if distracted by other work, can lose their sense of context. Style sheets may be used to help
maintain this sense of context through color. The <div> and <span> tags are intended to provide page
designer-defined content-based style. By defining classes of <div> tags with various colors and border
styles, the designer may provide additional information. It is important to bear in mind that a significant
number of people suffer from some form of color blindness. Thus, it may be necessary to design pages
both with and without using color styles.
User Interaction
As discussed above, HTML forms work reasonably well in the browser. However, due to the limitations
of the phone as an input device, keyboard input can be difficult. A complete keyboard is made available
based on the context of mouse selection. When a text input control is on-screen, the user simply needs to
click on the input control. The keyboard appears, with the browser thrown into a small scrolling area. The
input control is roughly centered in the scrolling area. The user may then press the software keys and the
text is shown in the input control. Simply pressing the done button dismisses the keyboard, and the input
control shows the newly typed text. While this interaction technically works fine, from a user perspective,
it can be difficult to type a large amount of text. Thus, unless user input is absolutely necessary, it should
be avoided. When necessary, user input should be kept to a minimum.
Click-to-Dial Functionality
Embedded as <a href="javascript:dial(’nnnn’)"> nnnn is passed to the Phone application to
initiate a phone call.
Example:
<html><head>

<table border="0" width="100%">

Creating Web sites for the 4610SW
and 4620 IP Telephones
Introduction
This Appendix describes the capabilities and limitations of the web browser in the 4610SW and 4620 IP
Telephones and provides suggestions for designing Web sites for viewing on those telephones. It is
intended for 4610SW and 4620 IP Telephone Web Browser (web page) designers, and assumes readers
are somewhat familiar with WML.
This Appendix serves the following functions:
• Presents the portions of WML that have been implemented in the 4610SW and 4620 IP Telephone
Web Access applications, including any limitations or non-standard implementations
• Provides considerations for developing effective web pages to be viewed in the browser
This Appendix is not intended to provide technical details on setting up a web server, nor does it provide
information on web server technologies. Finally, this document is not intended to provide an introduction
to web browser protocols or technologies.
NOTE:
All references to the 4620 IP Telephone in this appendix apply equally to the 4620SW IP
Telephone.
General Background
The 4620 IP Telephone has a 168 pixel-by-132 pixel four gray scale LCD display. The area of the display
available for presenting a WML web page to the user is 153 pixels across by 96 pixels in height, arranged
in 6 rows each 16 pixels in height. In addition, the top row will display the web page title (if any) and the
bottom row presents up to four softkey labels at one time, used for <do> tags, each a maximum of 6
characters.
The 4610SW IP Telephone has a 168 pixel-by-80 pixel four gray scale LCD display. The area available
for presenting a WML web page to the user is 153 pixels across by 44 pixels in height. In addition, the top
row will display the web page title (if any) and the bottom row presents up to four softkey labels at one
time, used for <do> tags, each a maximum of 6 characters. The 4610SW supports all the data types,
features, tags, etc. that the 4620 supports. The only difference is the size of the display. Unless otherwise
indicated, all subsequent references to the 4620 IP Telephone and its Web application apply equally to the
4610SW IP Telephone.
The data types and other features supported in this browser include:
• WML 1.3, June 2002
• HTTP 1.1

WML Document Skeleton
A chart at the end of this Appendix summarizes the more detailed information that follows.
NOTE:
Unsupported WML 1.3 tags will not be rendered and will not cause the browser to fail.
Unknown tags and misspelled tags will cause an error message.
WML Document Skeleton
Certain tags define the basic framework of a WML document. The tags listed below make up the basic
skeleton of a WML document, and are supported by the 4620 unless otherwise indicated.
• Common tag attributes: xml:lang, class, and id.
The attributes xml:lang, class and id are universal attributes associated with every WML
element.
The web browser will support these tags as follows:

• <wml> tag - The <wml> tag defines a deck of cards and encloses all information the deck and is a
required WML element. This tag must contain at least one <card> tag.
• <head> tag - The <head> tag is an optional WML tag containing information relating to the deck
as a whole, including meta-data and access control elements. This tag is not supported.
• <meta/> tag - The optional <meta> tag is contained between multiple <head> tags. This tag gives
values for the parameters that describe the content of the deck. This tag is not supported.
• <card> tag - A single WML file can contain multiple cards. This leads to the analogy - a “deck” of
“cards” within a single WML file. A “card” is essentially the specification of one specific WML
page. This is a mandatory tag.
The card element attributes supported by the web browser are as follows (unsupported attributes are
indicated as such in the Comments column):

Event Elements
• <do> tag - The <do> tag is a card-level user interface. It serves as a general mechanism for the
user to activate a task, typically performed by the user clicking on a word or phrase in the display.
A task is performed in response to an event. There are four tasks in WML: go, noop, prev, and
refresh.
The mandatory type attribute provides information about the intent of the element, helping to improve
processing. If the 4620 web browser does not recognize the specified type, (e.g., testing, experimental,
and vendor specific types), the specified type is treated as unknown. The browser only renders WML 1.2
tags. Any other tags will cause an error and the user will receive an error statement “not a valid wml

<do> tags are rendered as softkey labels on the bottom line of the 4620 display. <do> tags are specified
per WML page and therefore are page context-sensitive. The eight “do” types are labeled either
specifically in a WML page or by a browser-dependent label.
If no labels are given, then the “do” types will have the following default labels:

If more than one page of softkey labels are specified, pressing the MORE softkey
automatically presents the user with the next page of labels. If the last page displays and
the user presses the MORE softkey, the first page of labels is then displayed. As implied
by the above, the softkey buttons are labeled in sequential order of the <do> tags.

Event Elements
• <onevent> tag - The onevent tag serves as a container for code that you wish to be executed
automatically when one of the four intrinsic events occurs. The onevent element is said to bind
(associate) the tasks (code) to the event for the element. The intrinsic event must be specified
using the mandatory type attribute.
For example, when a user presses the BACK softkey, instead of being routed to the previous
screen, the user will be directed to another specified page because this tag carries out a onevent
backward event.
The intrinsic events are:

• <go> tag - The go element can contain one or more postfield elements. If the destination of a go
element is a card within the same deck, all of the postfield elements will be ignored. The go
element can also contain one or more setvar elements. Unlike postfield elements, there are no
destination limitations on passing information contained in the setvar elements. The <go> nested

method
post
Sets how to send the data to the server. Default
method is get. When method=”get”, the data is
sent as a request with?data appended to the
URL. The disadvantage of get is that it can be
used only for a limited amount of data; if you
send sensitive information it will be displayed
on the screen and saved in the web server's logs.
With method=”post”, the data is sent as a request
with the data sent in the body of the request. This
method has no limit, and sensitive information is
not visible. The data sent in a get method is
limited to ASCII characters. The data sent in a
post method may include non-ASCII characters
that are included as part of a value attribute in an
<input>, <select>, or <option> tag that is part of
the current WML page.
SUPPORTED
If set to true, the browser sends the URL of the

• <noop> tag - The noop tag dictates that no operation should be done. This tag can be used on the
card level to prevent an event, specified on the deck level by the template element, from
occurring. It can only be contained in either a do or onevent element.
An example of noop is to use a <do> tag to add a “Back” link to the card. When users click on the “Back”
link, generally they should be taken back to the previous card. However, the <noop> tag prevents this
operation; when the user clicks on the “Back” link nothing happens.
• <prev> tag - The prev tag specifies navigation to the previous URL in the history.
• <refresh> tag - The refresh tag specifies a refresh task whereby the whatever card is being
displayed will be refreshed. This task specifies the need for an update of the user agent context as
specified by the contained <setvar> elements.This tag can only be nested inside an anchor, do, or
onevent element. Xml:lang is not an associated attribute. User-visible side effects of the update
can occur during the processing of the <refresh>.

Input Elements
When a user views a page with the input tag specified, the first thing that shows up in the top line is the
card title, if specified. When the user scrolls to the first line containing input, the top line shows the input
box title if specified, otherwise the card title is shown. The top line displays the card title for all non-input
text.
When the input box is selected, a vertical line (the “cursor”) appears at the left side of the input box.
The attribute type password should only be used when it is important to not display the user' s password
on the screen. Asterisks will be displayed instead. It is also important that the password not be cached.
The phrase [enter text here] appears for all input tags if the value attribute is null. If the author specifies a
non-null content in the value attribute, that content displays between brackets for that input tag.
Only the correct size, type, and number of characters are accepted in to the input box. For example, if
alpha text is specified and the user types in a symbol or numeric text, the user input is not accepted. The
screen repaints and the user has to re-enter their input. If the wrong kind of text is typed, the user receives
an error tone. If the “n” (number) value is specified and the user types in the incorrect number of
characters, their input will not be accepted.
• <fieldset> tag - The fieldset tag is used to group logically related elements in a card. This tag is

Character Entities
Character Entities
As with any syntactic language, WML has certain characters that have special meaning. The two most
obvious of these characters are the < and > symbols, which surround all tags. These characters cannot be
typed in directly if the designer’s intent is to display these characters. Thus, all characters that can be
displayed in a web browser have numeric values assigned to them. The numeric values are entered into
the source web page as &#nnn; where nnn is a three-digit value. For example, the < symbol is entered as
’&#060;’.
In addition, many of these characters also have names assigned. Name values are entered into the source
web page as &name; where name is the WML name associated with this character. For example, the <
symbol would be entered as ’&lt;’. The set of characters defined by the World Wide Web Consortium are
fully supported in the 4620 browser in conformance with the standard.
For convenience, a few of these key symbols are specified below.

Colors and Fonts
The browser supports a 4-grayscale display. Because of the size of the screen on the 4620 IP Telephone,
the browser has only a single font available for use, which is based on Latin-1. Only a normal font weight
is supported. Bold, italic and different font sizes are not supported. The font used by the 4620 defines
characters to have at most six pixels in width.
Wireless Telephony Applications (WTA)
Wireless Telephony Applications (WTA) are those applications designed to interact with the telephonyrelated functions present in a phone. The web browser supports:
• Originating a call - Click to Dial
• Adding entries to the phonebook (Add to Speed Dial entries)
The Web Browser supports the WTA application “click to dial” any link on the screen. An icon of a
telephone handset is displayed to the left of a “click to dial” link when the link is initially displayed.
The Add to Phonebook WTAI function “wtai://wp/ap;” is used to add a Name and Number to the 4620
Speed Dial application. A Speed Dial icon will be displayed to the left of an “add to phonebook”. The
wtai syntax is supported as a href attribute and as such any tags that support the href attribute will be able

to use the “add to speed dial” function. These tags are <a>, <anchor>, <img>, <do>, <onevent>,
<select>, <option>, and <optgroup>.
When a user activates the “add to speed dial” function, the web will transfer the name and number to the
Speed Dial application, and the user will have the opportunity to edit the entry according to the current
Speed Dial functionality.
The WTAI URI scheme is as follows:
wtai://<library>/<function> (; <parameter>)* [! <result>]
Scheme Definition:
<>
Denotes an enumerated operator.
[]
Denotes an optional section.
I
Denotes a pair of mutually exclusive options.
( )*
Repeat none or multiple items.
*( )
Repeat one or multiple items.
library
Name that identifies the library type, WTA Public uses library “wp”.
function
Function within a library, for example, “mc” for function “make call” in “wp” library.
parameter
Zero or more parameters sent to a function; should be delineated by a semicolon “;”.
result
Start of result defined by “!”. Optional.
Syntax Implementation
Click to Dial Functionality
To enable the click to dial functionality, use the following syntax:
wtai://wp/mc;number
This code can be embedded into any valid WML tag that implements href or a hyperlink such as <a> tag,

Administering the 4610SW and 4620
Thin Client Directories
Introduction
If you have a corporate database that supports the Lightweight Directory Access Protocol (LDAP),
Avaya’s Thin Client Directory application can communicate with that database. Your 4610SW and 4620
IP Telephone users can then use their phones to search for names, telephone numbers, or other
information, and use the results of their searches to call a person directly, store a number on a Speed Dial
button, and/or view more details about the person.
This appendix provides the information needed to install and administer Avaya’s Thin Client Directory. It
has four primary sections:
• Application Platform Requirements - Describes the operating environment for the Thin Client
Directory application.
• Installing the Thin Client Directory on the Server - Lists the Avaya-provided download files
needed for installation, pre-installation requirements, and step-by-step installation instructions.
• Web Application User Interface - Describes and illustrates the Directory application screens with
which 4610SW and 4620 IP Telephone users perform Directory searches and review search
results.
• Directory Database Administration Interface - Describes and illustrates the administration screens
with which you define LDAP attributes and configure the user interface screens.
Figure 4, High-Level Thin Client Architecture, on page 138 provides a high-level overview of the Thin
Client architecture.
NOTE:
All subsequent references to the 4620 IP Telephone apply equally to the 4610SW and
4620SW IP Telephones.

As shown above, the Directory application and its administration are co-resident with an HTTP server.
Administration screens allow all Directory application parameters (such as the directory database server’s
IP address or DNS name, allowable search fields, results returned, etc.) to be set via a PC browser (web
browser may be co-resident on Directory Application Server).
When a 4620 IP Telephone user initiates a directory search, the user’s browser sends the search criteria to
the Directory application. The Directory application sends a query (based on administered parameters) to
the directory database (usually located on a separate server). The directory database server then returns
search results to the Directory application, which formats them in the appropriate markup language and
sends the results back to the end user. The user then has several options regarding the search results.

Application Platform Requirements
Application Platform Requirements
It is the LAN or System Administrator’s responsibility to provide and configure the LDAP server and the
operating environment on which the Thin Client Directory will be installed.
The recommended server configuration is Red Hat for Linux 8.0 (or greater) software; this version
facilitates optimal, automatic Thin Client Directory application installation. Other configurations (not
recommended by Avaya) require HTTP/Apache 2.0 and PHP Version 4.2.0 (with Version 4.2.4
preferred).
Installing the Thin Client Directory on the Server
Pre-Installation Requirements (Apache/PHP)
Before installing the Thin Client Directory application, the PHP Apache module (included with Red Hat
8.0) must be installed. If necessary, you can download this module for free from the
http://www.php.net/downloads.php Web site. Go to http://www.php.net for installation instructions,
otherwise, the distribution you download will contain its own set of installation instructions.
If you are not using Red Hat 8.0 or greater, Apache must be configured to accept PHP so the web server
recognizes it. This process differs depending on whether PHP is being installed on Linux or Windows.
Further configuration variations depend on the Apache version installed.
Avaya-Provided Download Files
Two Thin Client Directory application versions are available from the Avaya Web site at:
http://avaya.com/support
The recommended download version (avayadir-1.0-1.0.i386.rpm) is for Red Hat Linux 8.0 (or greater)
installations only. This download allows the Red Hat Package Manager to automatically install the
required directories and associated files in the correct locations.
NOTE:
A README file containing Thin Client Directory Application installation instructions is
also available from the Avaya Web site, if needed.
The other version available is a Winzip-readable file, for those installations with Windows or any other
operating system that are not using Red Hat for Linux 8.0 (or greater). This version requires you to select
specific files to download and perform additional server/file customization to properly install the Thin
Client Directory application.

Administering the 4610SW and 4620 Thin Client Directories
Installing the Thin Client Directory on the Server
The download contains these directories:
• avayadiradmin - Files needed for the HTML administration part of the LDAP application
(including the PHP files needed for administration).
• avayadirclient - Files necessary for the 4620 user interface (the files that perform the search
query and return search results to the telephone’s display screen).
• avayadir.ini - Files containing settings that control the (administration and client) application.
This is a protected directory that cannot be browsed. During the unzip process, it is placed in the
same root as the other two sub-directories. If desired, you may move this directory outside of the
HTML path, providing the new path is PHP-accessible.
• avaydirinclude - Common files shared between the Directory administration and client
(end user) interface.
• avayadirerror - Text files for search-related error message generation.
• avayadirhelp - Text files containing end user Directory assistance.
Installing the Thin Client Directory
Installations using Red Hat for Linux 8.0 (or
greater):

To enable password control for the Directory Administration Application, create a directory entry
in the httpd.conf file as follows:
Copy the entire tree that was created by running unzip under the documentRoot of the httpd
server. For example, if your directory is /var/www/html, the directory created will be
/var/www/html/avayadir.
NOTE:

Extract the file avayadir-1.0.zip to the documentRoot folder.
NOTE:
Making LDAP/PHP work with Apache is not necessarily easy. The procedure below
contains the basics, but for further information, you may wish to download a free white
paper available on the Avaya Support Web site. After accessing the Avaya Support Web
site, make the following selections: Telephone Devices & User Agents, then IP
Telephones & User Agents, then 4600 IP Telephones and SDK and Browser
Information.
The documentRoot location will vary based on web server installation. This is the
directory where the web server originates the files it serves.

Go to www.php.net to determine how to install and configure PHP for your server.
Check your web server’s installation instructions to determine how to enable directory-level
password control. It is strongly recommended that you enable password protection for the
Directory administration folder avayadiradmin.
Open the file php.ini for editing. This file should be located in the Windows folder c:\windows.
In php.ini, set the option “short_open_tag = On”.
Uncomment the line “extension=php_ldap.dll”
Save the updated php.ini file.
To finish, restart the web server.
Now test everything out by pointing a browser at the newly created directory structure such as:
<http://yourserver/avayadir/avayadiradmin/index.htm>.
Web Application User Interface
This section describes the user interface screens required for the Directory application. Because the
Directory application’s phone screens are accessed via the 4620’s Web Access application, any Directory
user interface screen you administer must use LDAP attributes only. Some examples are provided in
Table 19, List of Drop-Down Attributes available for Search, Query and Details Administration Screens,
on page 156. Appendix C, “Creating Web sites for the 4610SW and 4620 IP Telephones” provides
detailed information about how web pages/screens are rendered for the 4620 IP Telephones. Once you
familiarize yourself with the user interface, see Directory Database Administration Interface for
instructions on completing the associated administration screens.
NOTE:
Because the Directory user interface screens are considered part of a web-based
application, and because you may customize user interface screens, specific user
instructions regarding the Directory application are not provided in the 4620 IP Telephone
User’s Guide. Chapter 5, Using the Web Access Application, provides general information
for working with web pages.

Search responses take one of two forms. A successful search (one returning at least one telephone number
when a Name was provided as search criteria) displays the Successful Search screen. This screen offers
options to call the number found, add it to a Speed Dial button or review more detail. An unsuccessful
search (no name found, error report(s) and/or unintelligible responses) displays the Directory Trouble
screen.
NOTE:
You administer the Search screen using the Search Administration screen, covered in
Configuring the Directory Application Search Administration Screen on page 152.
Web Application Successful Search Screen
The Successful Search screen displays when at least one match results from a user-submitted search. The
top display line provides the message X found. Select choice. (where X = the number of matches
found) or the message More results - please try again and refine search. (to indicate
more than 96 matches were found). The display area for this screen provides the name and phone number
of up to 96 matches found by the search. The user scrolls through the matches using the web browser
navigation key to move forward one page, and selects an entry by pressing the Feature button to the left
of the entry.

NOTE:
The Directory Application administration interface is in the English language only.
Each screen has required and optional parameters. The input fields have a definition and/or explanation
of what is required to their right in the yellow areas. There may also be yellow Help areas at the bottom of
a screen to help you populate the screens correctly. You can select the Home option from the left side of
any administration screen to return to the Welcome screen (Home page).
The bottom of each screen provides navigation and save options, as illustrated below:
After entering the values for a screen, press the Save Changes button to save your entries, then use the
Right Arrow or Left Arrow buttons to move from that screen to another. Pressing an arrow button
without first saving what you entered or changed causes a dialog box to display. The dialog box lets you
confirm that you do not want to retain your entries (or any changes you’ve made to existing values) or
allows you to select Cancel to return to the screen and save the data.
Configuring the required information in accordance with the instructions in this section allows the Thin
Client Directory application to communicate properly with the LDAP server. After configuring and
saving the required information, test the Directory application to be sure the user interface screen values
are correct, that the application is interfacing properly with the LDAP server, and that the Directory
Application server is interfacing properly with the end user’s phone.

Example: Line 3 above shows a search field “Email” with the LDAP attribute “mail.” If you enter the
Associated Label (column 4) as “Email Address” the 4620 users’ Search screen third line prompts them
to “Enter Email Address Here”.
You can populate fields with well-known LDAP attributes from an Avaya-provided drop-down list. Table
19, List of Drop-Down Attributes available for Search, Query and Details Administration Screens, on
page 156 provides a list of allowable attributes you can use to label such fields.
Configuring the Directory Application Details
Administration Screen
The Detail screen’s administration requires you to provide the LDAP attributes that will appear on the
user interface Details screen; these are the details the end user sees about a selected person when the
Details screen displays.

Enter the LDAP attribute names representing the detail information you want to display about a
person found by a search. These entries appear to your 4620 end users on the user interface Detail
screen, as illustrated in Web Application Detail Screen on page 145.
NOTE:
It is assumed that a minimum of name and telephone number will be shown as detail
information, but you can change these defaults and provide different attributes, if desired.
To override an attribute that does not appear in a drop-down list, change the Use Other
radio box next to the appropriate Displayed Attribute from “Yes” to “No” then enter the
custom attribute in the Other text entry field.
Labels are not required because the detail attribute should be unique enough for end user
identification. If you feel the attribute does not provide a sufficient description, you may
include a label of up to 8 or less characters, with the understanding that the number of
characters in the text display area will be reduced accordingly.
You can populate LDAP attributes from an Avaya-provided drop-down list. Table 19, List of Drop-Down
Attributes available for Search, Query and Details Administration Screens, on page 156 provides a list of
allowable attributes you can use to label such fields.

Configuring the Directory Application Softkey
Administration Screen
Avaya provides specific softkeys with specific functions on each user interface screen. Where space is
available in the softkey area at the bottom of a (user interface) screen, you may optionally configure up to
five additional softkeys and link them to specific Detail screen display fields. For example, you may have
configured “Manager” as a detail screen attribute, which would show a [found] person’s manager as part
of the detail information. Linking a softkey to that field can provide a report/list of any person in the
directory who has that specific manager as part of his or her own detail information.
The Softkey Administration screen lists all attributes you previously defined on the Detail Administration
screen as “From” attributes. You configure softkeys by providing a “To” attribute that establishes a link
between the two attributes, and which is used as the softkey’s label. You can populate LDAP “To”
attributes using an Avaya-provided drop-down list as shown in Table 19, List of Drop-Down Attributes
available for Search, Query and Details Administration Screens, on page 156. You may also provide a
specific label for the new softkey, using the minimal number of characters that will display in the screen’s
softkey label area.

4610SW/4620/4620SW Push Feature
Introduction
E
4610SW/4620/4620SW Push Feature
Introduction
Release 2.1 of the 4600 Series IP Telephones provides support for a new feature called “Push,” which
applies to the 4610SW, 4620, and 4620SW telephones. Push gives the System Administrator the
capability to use WML protocol to send content to a telephone without the user requesting it, and to
(potentially) override what the user is otherwise experiencing. You can send pushed content to a single
phone, a group of phones, or the entire enterprise.
Push Content
Three types of content can be pushed, with one of two types of priorities (normal and barge-in). The
content types are:
• Text Messages on the top display line. If a pushed text message has barge-in priority, the message
overwrites whatever else is currently displayed (although other subsequent messages may, in turn,
overwrite the pushed message). If the pushed text message has normal priority, it is buffered in the
telephone and displayed when no higher priority message is being displayed.
• WML Web pages can be pushed to the telephone’s WML browser. If a pushed Web page has
barge-in priority, the content overwrites whatever else is currently displayed to the user.
If the push of a Web page has normal priority, the Web page does not override what the user sees.
If the user has the Web application displayed, the normal-priority pushed content overrides what
is otherwise displayed. If the Web application is not being displayed, the normal-priority pushed
content is loaded in the background and presented to the user when the Web application is
invoked, subject to certain restrictions. In this case, you may wish to accompany the web push
with a corresponding pushed text message, to alert the user that there is Web content to view.
• Audio Messages (RTP) can be pushed. Pushed audio messages can drive the telephone off-hook,
if necessary and play the pushed message through the telephone’s speaker. If the audio push has
barge-in priority, the audio message is presented to the user, even if the user is on a call. In this
latter case, the far end is automatically placed on Hold and does not hear the pushed audio
message.
A given push can include any or all of the three content forms, but can have only one priority. You can
optionally accompany each push with notification tones to draw the user’s attention to the phone (and
hence to the pushed content).

4610SW/4620/4620SW Push Feature
Push Priorities
Push Priorities
Barge-in pushes, as the name implies, are meant for information important to get to the user. An example
of a barge-in push could be an audio message alerting users that the building is closing due to inclement
weather, accompanied by a Web page detailing weather conditions. There are very few circumstances that
would prevent barge-in pushes from being presented to the user (although of course, network conditions
may prevent delivery of the pushed content).
Use normal pushes for less-essential or less time-critical information. An example could be “Mary has
birthday cake in her office.” A normal push may or may not be presented to the user. For example, a
normal audio push is not presented to a user already on a call or a normal text message not displayed until
a higher priority message is completed.
For More Information on Push
The specifications and interactions of pushed content are beyond the scope of this document. Further
information, including sample applications, is available in a Software Developer Toolkit on the Avaya
support Web site, http://www.avaya.com/support.
