Introduction
The H.323 standard is a set of specifications that enables real-time multimedia
communication over packet-based networks.
H.323 covers the format of the data packets, coding and compression standards, signaling and flow control.
H.32x standards
The H.32x set of standards contains other standards for voice, video and data
transmission in addition to H.323. It has been created by the International Telecommunications Union (ITU), an organization within the United Nations that
deals with the coordination of telecommunication networks and services around
the globe.
The H.32x family comprises the following:
Standard
Network
H.320
ISDN
H.321
ATM-based broadband ISDN (B-ISDN)
H.322
LAN with guaranteed quality of service

H.32x family standards and associated networks
The H.323 standard enables modern communication equipment and facilities to
be used in the accustomed working environment, e.g. ➤➤ IP telephony, video conferences (Microsoft NetMeeting etc.), ➤➤ Computer Telephony Integration, Desktop Sharing and ➤➤ Unified Messaging.
H.323 defines specifications for existing infrastructure. Nothing needs to be
changed on existing packet-based networks. H.323 can be used on all IP-based
networks such as ➤➤ LANs, ➤➤ WANs and the Internet.

H.323

Overview of H.323
H.323 is independent of platform, i.e. it is independent of the hardware and operating system used.
Solutions from different manufacturers can be combined using H.323 as a basis. The participants in a video conference, for example, can use different hardware. The devices are compatible as long as they are equipped with H.323.
H.323 and firewalls
Corporate networks are normally hidden behind a ➤➤ firewall to protect sensitive corporate data against external access.
A video conference or IP telephony, however, cannot be operated so easily
over a firewall. H.323 needs dynamically changing ports, whereas a firewall normally only opens certain ports for certain IP packets. An H.323 proxy solves this
problem.
H.323 at BinTec
BinTec Communications AG has integrated the H.323 proxy and H.323 gatekeeper features in its X-Generation products in Software Release 6.2.1. The
proxy and gatekeeper features and the IPSec security solution are not available
at the same time in X1000, X1200 and X3200.
BinTec’s solutions are based on version 2 of the H.323 standard.
1.2
Overview of H.323
The H.323 standard defines the components and methods used to transport
voice, video and data over packet-based networks.
This chapter contains the following information:
■ what components are found in an H.323 network
■ what protocols are necessary for communication
■ for what purpose the components use certain protocols
■ the basic procedure for a call.

Technology Overview
1.2.1
H.323 Components
A network based on the H.323 standard contains the following components:
■ H.323 terminal
■ Gateway (optional)
■ Gatekeeper
■ Multipoint Control Unit (MCU, optional).
These components provide point-to-point and point-to-multipoint connections in
an IP network, i.e. it is possible to communicate with only one partner or with
several partners simultaneously.
Apart from the above-mentioned components, additional components, such as
firewall and proxy, can also be integrated in the network to include the security
aspects that the H.323 standard does not cover.
Zone, endpoint
All the terminals, gateways and MCUs administrated by a single gatekeeper are
designated as an H.323 zone. A zone comprises at least one gatekeeper and
one terminal and can also contain other terminals, gateways and MCUs.
Terminals, gateways and MCUs are also designated as endpoints.
Although gatekeeper, gateway and MCU are different logical components of the
H.323 standard, they can be implemented in a single device.
The individual components in the H.323 network have certain properties and
tasks, which are described in detail below.
Terminal
An H.323 terminal is an endpoint in the network that provides communication to
another H.323 terminal, gateway or Multipoint Control Unit.
This is either a Personal Computer (PC) or another device on which H.323 protocols (see "H.323 Protocols", page 14) are available. For example, an IP telephone is a terminal in ➤➤ Voice over IP.
10
Software Reference
H.323
A
Overview of H.323
H.323 terminals can send and receive voice in real time, plus video and data as
options. The H.323 standard therefore provides a basis for telephone connections over IP networks.
Gateway
A gateway can be implemented as a separate device or in software form.
An H.323 gateway connects an H.323 network to a network of another standard, e.g. to H.320 or H.324 (see table A-1, page 8). This involves translating
the protocols, converting the formats, transforming the communication procedures and exchanging information between the networks.
A suitable gateway can, for example, enable communication between an H.323
network and the ➤➤ PSTN, i.e. set up a connection from IP telephones to telephones in the conventional telephone network.
A gateway is not necessary if communication is only to take place within a single network, e.g. within a single LAN.
Gatekeeper
The H.323 gatekeeper is always implemented as software. It is the "brain" of
the network and the common point for all connections. The gatekeeper monitors
all ➤➤ calls. Its main tasks are the admission of a call and address resolution
in its zone. For this purpose, the endpoints for which a gatekeeper is to be responsible must register with this gatekeeper.
Although terminals can communicate directly, they should use the services of
the gatekeeper if one is available in the network.
The gatekeeper provides important services for registered endpoints, some of
which are available at every gatekeeper and some are optional.
Gatekeeper functions
The following gatekeeper functions are always available:
■ Address translation: Translation of an alias or telephone number
(➤➤ E.164 address) to an IP address.
■ Access control: Access control to the LAN can be provided via call authorization, the bandwidth or other criteria.
H.323
Software Reference
11
A
Technology Overview
■ Bandwidth control: Bandwidth can be controlled via bandwidth management according to previously defined criteria. For example, it is possible to
limit the number of connections available simultaneously. This also limits
the bandwidth used and the remaining bandwidth can be used for other
purposes, e.g. data applications.
■ Zone management: The gatekeeper provides the above functions for the
terminals, gateways and MCUs registered in its zone.
The following gatekeeper functions are optional:
■ Call control signaling: In a point-to-point connection, the gatekeeper either
routes the Q.931 packets for call control or instructs the endpoints to communicate with each other directly.
■ Call authorization: The gatekeeper can reject a request from a terminal or
gateway to set up a call. The reasons can include restricted access to or
from certain terminals or gateways or restricted access to certain devices
at certain times.
■ Bandwidth management: The gatekeeper can reject a call setup from a terminal if the bandwidth is not sufficient.
■ Call management: The gatekeeper can maintain a list of the presently active calls to indicate that a called terminal is busy or to provide information
for bandwidth management.
■ Routing service: The gatekeeper can route calls over various paths in order
to ensure even utilization of the network.
Multipoint Control Unit
Multipoint Control Units (MCUs) can be implemented as software or hardware.
An MCU always contains a Multipoint Controller (MC) and optionally one or
more Multipoint Processors (MP).
MCUs support a conference of three or more H.323 terminals. All terminals that
take part in the conference set up a connection to the MCU. The MCU controls
the conference resources and supports the negotiation of a common audio
and/or video ➤➤ CODEC (see also "Audio", page 16 and "Video", page 16).
The MCU can also control the traffic flow as an option.
12
Software Reference
H.323
A
Overview of H.323
There are two kinds of multipoint conferences: centralized and decentralized. A
combination of both is also possible. Centralized multipoint conferences are
mostly implemented, which requires an MCU. Decentralized multipoint conferences manage without an MCU, but need more computing power in the endpoints.
Proxy Server
Every corporate network is normally protected by a firewall against unauthorized access from outside, e.g. from the Internet.
Some communication services such as IP telephony or video conferencing are,
however, dependent on overcoming the firewall so that partners inside and outside the corporate network can communicate with each other. The firewall
should naturally not lose its function due to this process, but continue to protect
the data in the corporate network.
An H.323 proxy server in combination with a firewall provides security functions
for the above case. The data traffic arriving at the firewall is reflected by the
proxy at the firewall. The addresses are translated by the proxy. The proxy fulfills its proxy function, but no direct connection is set up between, for example,
the corporate network and the Internet. The proxy passes on the information to
the respective other side, but without revealing the origin of this information.
Proxies not only protect the data, they also support bandwidth reservation or
prioritization of data traffic. This ensures a reasonable quality of service for
H.323 connections, although H.323 networks do not possess any guaranteed
quality of service.
Advantages
A proxy has the following advantages:
■ There are no direct connections between the internal and external system.
■ A proxy can create comprehensive log files on data traffic and specific activities.
■ A proxy supports user level authentication.
■ A proxy analyzes the data packets.
H.323
Software Reference
13

Technology Overview
■ Newer proxies ensure transparency, i.e. the ➤➤ clients behind the firewall do not need to "know" that the proxy exists and do not need special
software to communicate with the external network.
1.2.2
H.323 Protocols
Protocols control the interaction between the H.323 components.
The H.323 standard defines the following for voice, video and data transmission:
■ how endpoints set up connections to each other
■ how endpoints negotiate the pool of audio, video and data formats they
want to use
■ how voice, video and data are formatted and sent over the network
■ how voice, video and data are synchronized
■ how endpoints communicate with the responsible gatekeepers.
Different groups of protocols from the H.323 standard are required according to
application.
H.323 uses the two transport protocols
on what is to be transmitted.
➤➤ TCP and ➤➤ UDP, depending
The following protocols are defined in the H.323 standard. Some of these are

Technology Overview
Audio
An audio ➤➤ CODEC encodes, i.e. digitizes and compresses, an analog
sound signal from the microphone to enable it to be transmitted over the network to the receiver. The transmitted signal is decoded by the CODEC at the
receiver, i.e. decompressed and reconverted to an analog signal for output to a
speaker.
As the transmission of sound signals is always available with H.323, all H.323
terminals must support at least one common voice coding process to be able to
communicate with each other. This common voice coding process is called audio CODEC and operates to the G.711 standard at 56 kbps or 64 kbps.
The G.722 (48 kbps, 56 kbps or 64 kbps), G.723.1 (5.3 kbps or 6.3 kbps),
G.726 (16 kbps, 24 kbps, 32 kbps or 40 kbps), G.728 (16 kbps) and G.729 A or
G.729 B (each 8 kbps) standards can also be supported as optional standards
with H.323.
Video
A video ➤➤ CODEC encodes a video signal before it is sent over the H.323
network. The received video code is decoded by the video CODEC and displayed on the video equipment.
H.323 provides the transmission of video signals as an option. Support for one
or more video coding processes is therefore also optional. If an H.323 terminal
permits video communication, it must also support a video CODEC, i.e. at least
H.261 ➤➤ QCIF.
If the bandwidth is low, the H.263 and H.263+ video CODECs provide better
video quality than H.261.
Data
The T.120 protocol is used for data transmission and is included in the H.323
standard as an option. T.120 enables applications such as shared access to a
whiteboard by several users, Application Sharing, File Transfer, etc.
Microsoft NetMeeting, which also supports T.120, enables conferences to be
held over the network. T.120 supports the setting up and control of the data
flow, the connections and the actual conference.

Overview of H.323
Communication and Control
Apart from the protocols for coding and formatting voice, video and data, transmission over the network also requires various communication and control protocols, whose tasks are briefly described below.
H.225 Registration,
Admission and Status
(RAS)
The RAS (Registration, Admission and Status) protocol is required for communication between the endpoint and gatekeeper. RAS is not needed if no gatekeeper is used.
The protocol helps the endpoints to find the gatekeeper responsible for them
and to register with this gatekeeper. RAS also controls the access of endpoints
to the H.323 network, any bandwidth changes, the status of a connection and
ending a connection between an endpoint and gatekeeper.
H.225 call signaling;
Q.931
H.245 control signaling
H.225 takes care of a call between H.323 endpoints.
The protocol is used for setting up and clearing a call and for call control between two endpoints. Signaling is based on the Q.931 ISDN signaling protocol.
This ensures a relatively simple gateway to the public telephone network.
H.245 is the media control protocol.
It negotiates endpoint functions, e.g. the voice coding process (audio CODEC).
H.245 also controls the logical channels for the transmission of voice, video and
data. The protocol controls the breakdown of the information into data packets
and the synchronization of the media flows. It also contains information on flow
control of the data and other control messages.
Real-time Transfer
Protocol (RTP)
The Real-time Transfer Protocol (RTP) is used for transporting voice and video
data.
RTP transports the audio and video traffic flow via ➤➤ UDP. Each UDP packet is given a header with a timestamp and sequence number. The header together with a suitable buffer is used at the receive terminal to sort the packets
into the correct order, remove duplicated packets and synchronize voice, video
and data.
Real-Time Control
Protocol (RTCP)
H.323
The Real-Time Control Protocol (RTCP) is the counterpart to the RTP, the control protocol for the RTP as it were.
Software Reference
17
A
Technology Overview
The RTCP monitors the quality of service and transfers information about the
users in the network. The RTCP also informs all users about the quality of data
delivery.
Security
To ensure comprehensive security for information transmitted on the basis of
the H.323 standard, the traffic flows must be protected. The control protocols
must also be transmitted securely.
The H.235 standard meets the following main requirements for providing secure data transmission:
■ User authentication
■ Data integrity check
■ Data confidentiality (encryption).
Other protocols
The H.323 standard defines other protocols and additional functionality, which
are not dealt with in this document.
1.2.3
Interaction between Components and Protocols
H.323 communication can be regarded as a mixture of voice, video, data and
control information. Each component in the network has certain tasks, which it
performs with the aid of the protocols.
A brief summary of the various protocols used by the individual components
and for what purposes is given below.
This is followed by a brief description of the sequence of steps necessary for a
➤➤ call.

Overview of H.323
Terminal
An H.323 terminal uses the following protocols:
■ H.245 is used to negotiate endpoint functions (audio CODECs, video CODECs, etc.), e.g. with another terminal. H.245 also controls the channels for
transporting voice, video and data from one terminal to another terminal.
■ H.225 call signaling is used for setting up and clearing a call and for call
control between two endpoints, e.g. between two terminals, a terminal and
a gateway or a terminal and an MCU.
■ RAS is necessary for the terminal to register with a gatekeeper and for control tasks in connection with the gatekeeper.
■ RTP/RTCP is used for sending and receiving audio and video data packets
and for defining their order.
Gateway
A gateway supports the translation of protocols and the transfer of information
between different types of networks, e.g. an IP network and an ➤➤ SCN network.
The following protocols are supported by the gateway on the H.323 side:
■ H.245 is used by a gateway for negotiating the endpoint functions and for
controlling the multimedia channels (see relevant item 1 under "Terminal",
page 19)
■ H.225 call signaling is used for setting up and clearing a call and for call
control between two endpoints, e.g. between a gateway and a terminal or
a gateway and an MCU.
■ RAS is necessary for a gateway to register with a gatekeeper and for control tasks in connection with the gatekeeper.
On the ➤➤ SCN side, the gateway supports SCN-specific protocols, e.g. the
➤➤ ISDN protocol and the ➤➤ SS7 protocol.
H.323
Software Reference
19
A
Technology Overview
Gatekeeper
The gatekeeper requires only the RAS protocol for its tasks. RAS ensures that
endpoints can register with the gatekeeper, i.e. enter its zone and announce
their addresses. The gatekeeper provides various services for the endpoints in
its zone (see "Gatekeeper functions", page 11).
Multipoint Control Unit
The Multipoint Controller (MC) in the MCU uses the H.245 protocol to negotiate
common voice and video coding processes between all terminals.
1.2.4
Basic Procedure for H.323 Communication
The following processes take place when an H.323 terminal communicates with
a second H.323 terminal:
1.
Call setup
Call setup uses the H.225 call control messages. Bandwidth is also reserved for the call.
2.
Initial communication and negotiation of endpoint functions
The endpoint functions, e.g. audio and video CODEC, are negotiated in a
separate H.245 control channel or over a Q.931 call signalling channel using H.245 messages.
3.
Configuring audiovisual communication
The logical channels for the information flows are opened by H.245.
4.
Services
Various services can support the call flow during a call:
A change in the bandwidth originally defined by the gatekeeper can be requested by the gatekeeper or a terminal at any time during a conference.
The gatekeeper can request periodic status messages from the endpoints
in order to determine if an endpoint is no longer active or if a fault has occurred.
A point-to-point connection between two terminals can be extended into a
conference, for which at least one MCU is necessary.

Ending the call
Either of the endpoints involved can end an active call. This is done by ending video transmission after a complete frame, ending data and sound
transmission and then closing the associated logical channels.

Introduction
You can operate IP telephones in your LAN with very little configuration effort.
Advantages of IP
telephones
IP telephones offer the following advantages:
Only a single network is required for data and telephony and no additional infrastructure is needed for telephony in the LAN. (You need a gateway for telephoning to the "outside world".)
Apart from the cost savings through the use of a single network for all communication, IP telephones have a direct advantage in everyday work: If an employee changes his workplace permanently or temporarily within the company, he
can take his telephone with him and connect it at his new workplace. No new
configuration is necessary and the employee is immediately available under the
usual telephone number.
You need no other components in addition to your BinTec router in order to operate IP telephones in the LAN.
Instead of an IP telephone, you can also use a PC with microphone or headset
and Microsoft NetMeeting for communication.
Procedure
Taking IP telephones into operation in the LAN and testing them is divided into
four steps:
■ Registering IP telephones with the BinTec gatekeeper (section B,
chapter 1.3.1, page 38)
■ Checking the registration (section B, chapter 1.3.2, page 41)
■ Making a test call (section B, chapter 1.3.3, page 42)
■ Displaying calls (section B, chapter 1.3.4, page 42).

➤ Install Software Release 6.2.1 without IPSec or purchase a BinTec X-Generation router that provides the IPSec and gatekeeper functionality at the
same time.
If you have Software Release 6.2.1 without IPSec, the gatekeeper is available.
Other X-Generation
routers
For all other X-Generation routers:
➤ Check if Software Release 6.2.1 is installed on your router. If your router
has an older software version, carry out a software update. You will find information about a software update in the User’s Guide for your BinTec router.

Registering IP Telephones with the BinTec
Gatekeeper
How to register your IP telephone with the gatekeeper of your BinTec router is
described below. The registration is described using the Innovaphone 200 as
an example. IP telephones of other manufacturers are registered in a similar
way.
To ensure that only certain IP telephones can register with your BinTec gatekeeper, enter the desired telephones in the USER TABLE of the gatekeeper. At
the IP telephone itself, enter the alias of the IP telephone and the IP address of
the gatekeeper with which the IP telephone is to register. The actual registration
takes place automatically.
Before you start, make sure the IP telephone already has an IP address or is
assigned an IP address. To reduce the configuration effort, you can obtain the
IP address via a DHCP server. If you would like to use your BinTec router as a

Summary
Registering NetMeeting with the BinTec Gatekeeper
Before an employee at a home office can communicate with his colleagues at
head office using Microsoft NetMeeting, NetMeeting must register with the
gatekeeper at the head office. The relevant requirements must be fulfilled for
both NetMeeting itself and for the BinTec router at the head office:
■ The administrator at the head office must assign a Username to the home
office employee and enter him in the gatekeeper’s USER TABLE. He must
ensure that this entry is used for registration.
■ The home office employee must configure NetMeeting so that it registers
with the gatekeeper of the BinTec router.
Procedure
48
The administrator of the BinTec router activates the proxy to ensure that NetMeeting has access to the corporate network.
Software Reference
H.323
B
Configuration and Monitoring
To ensure that the home office employee can be reached under his name and
the desired telephone number, the administrator enters the relevant data in the
USER TABLE of the gatekeeper.
The home office employee only enters in the NetMeeting program the alias and
the gatekeeper with which NetMeeting is to register. The actual registration
takes place automatically.
You can also use other H.323-capable endpoints instead of NetMeeting if they
are registered with the BinTec gatekeeper.

Making a Test Call to Head Office
To test if your NetMeeting at the home office can communicate with other NetMeeting users at the head office, set up a call to another NetMeeting user.
For example, call Erna Eiscreme with the alias ee_netmeeting and the telephone number 2468 (see figure B-2, page 48). She should be registered with
the gatekeeper under this data. You can enter the telephone number, the user
name or the alias for setting up the call.
Proceed as follows to set up a call to Erna Eiscreme:
Figure B-3: Setting up a call with NetMeeting
➤ Enter the desired telephone number in the NetMeeting you have already
started: 2468.
➤ You can also enter the user name or alias as an alternative to the telephone
number.

Access to Head Office with Microsoft NetMeeting
➤ Click the Place Call button to the right of the input field (i.e. the button with

The call is set up.
Communication is only possible in both directions if NetMeeting has already
been started at the home office and has registered with the gatekeeper at the
head office. This means: the employee at the home office can call a colleague
at the head office using NetMeeting and everyone at the head office can also
communicate with the colleague at the home office using Microsoft NetMeeting
or an IP telephone.
Once the connection between the home office and head office exists, it
remains open until Microsoft NetMeeting is closed at the home office. (An open
connection is necessary for the Time to Live (sec) parameter (see table A-5,
page 30).
We recommend that you use flat-rate Internet access.

NetMeeting and DynDNS with a
BinTec Router
3.1
Introduction
With a BinTec router, you can use Microsoft NetMeeting to communicate with
another NetMeeting user over the Internet.
DynDNS
Your router does not need a fixed IP address outside its LAN. The dynamic IP
address is announced via the BinTec router function "Dynamic DNS"
(DynDNS), if you have registered a host name for your router with a DynDNS
provider and have configured your router accordingly. Detailed information
about the "DynDNS" function can be found in Release Notes 6.2.2.
Your communication partner needs only a PC with Microsoft NetMeeting and
an ISDN card, or another direct dialing in facility, e.g. T-DSL with modem and
network card.
Procedure
In this case, the initial operation, test and use of Microsoft NetMeeting is divided
into four steps:
■ Registering NetMeeting with the BinTec gatekeeper (section B,
chapter 3.3.1, page 59)
■ Checking the registration (section B, chapter 3.3.2, page 63)
■ Making a test call (section B, chapter 3.3.3, page 64)
■ Displaying calls (section B, chapter 3.3.4, page 66).
3.2
Requirements
The use of flat-rate Internet access is recommended for using NetMeeting.

NetMeeting and DynDNS with a BinTec Router
For security reasons, BinTec Communications AG does not support the NetMeeting functions "Desktop Sharing" and "Whiteboard".
If you use NetMeeting together with the gatekeeper or proxy functionality, you
cannot use the "Internet Locator Server" from Microsoft.
Availability of H.323
proxy and H.323
gatekeeper
You can use Microsoft NetMeeting together with the gatekeeper and proxy
functionality of a BinTec X-Generation router with Software Release 6.2.1 or later. If you use X1000, X1200 or X3200 routers, the IPSec security solution and
the gatekeeper or proxy are not available at the same time.
Proceed as follows to make sure your router has the gatekeeper and proxy
functionality:
Router type
X1000, X1200, X3200
➤ Check which router type you are using.
For X1000, X1200 and X3200 routers:
➤ Check if your router is operated with the IPSec system software.
If you have Software Release 6.2.1 with IPSec:
➤ Install Software Release 6.2.1 without IPSec or purchase a BinTec X-Generation router that provides the IPSec and gatekeeper or proxy functionality
at the same time.
If you have Software Release 6.2.1 without IPSec, the gatekeeper and
proxy functionality is available.
Other X-Generation
routers
For all other X-Generation routers:
➤ Check if Software Release 6.2.1 is installed on your router. If your router
has an older software version, carry out a software update. You will find information about a software update in the User’s Guide for your BinTec router.

Summary
Registering NetMeeting with the BinTec Gatekeeper
"Partner 1" and "partner 2" (see figure B-4, page 59) must be registered with
the BinTec gatekeeper before they can communicate with each other. The relevant requirements must be fulfilled for both NetMeeting and the BinTec router:
■ The administrator of the BinTec router must assign a Username to both
partners and enter them in the USER TABLE of the gatekeeper. He must ensure that these entries are used for registration.
■ NetMeeting must be suitably configured for "partner 1" and "partner 2" (see
figure B-4, page 59) so that the respective NetMeeting registers with the
gatekeeper of the BinTec router.
Procedure
The administrator of the BinTec router activates the proxy to ensure that NetMeeting of "partner 2" has access to the network of "partner 1".
The administrator enters the desired data of the two communication partners in
the USER TABLE of the gatekeeper.

NetMeeting and DynDNS with Two
BinTec Routers
4.1
Introduction
As user of a BinTec router, you can use Microsoft NetMeeting to communicate
over the Internet with another NetMeeting user also reachable via a BinTec
router.
DynDNS
Neither of the BinTec routers needs a fixed IP address outside its LAN. The dynamic IP addresses are announced via the BinTec router function "Dynamic
DNS" (DynDNS), if you have registered a host name for each of the two routers
with a DynDNS provider and have configured the routers accordingly. Detailed
information about the "DynDNS" function can be found in Release Notes 6.2.2.
Procedure
In this case, the initial operation, test and use of Microsoft NetMeeting is divided
into four steps:
■ Registering NetMeeting with the BinTec gatekeeper (section B,
chapter 4.3.1, page 71)
■ Checking the registration (section B, chapter 4.3.2, page 76)
■ Making a test call (section B, chapter 4.3.3, page 77)
■ Displaying calls (section B, chapter 4.3.4, page 79).

For a special case, which you will also find in this scenario (see "Setting gatekeeper parameters", page 73 and "Making a Test Call", page 77), you do not
need flat-rate access to the Internet.
For security reasons, BinTec Communications AG does not support the NetMeeting functions "Desktop Sharing" and "Whiteboard".
If you use NetMeeting together with the gatekeeper or proxy functionality, you
cannot use the "Internet Locator Server" from Microsoft.
Availability of H.323
proxy and H.323

You can use Microsoft NetMeeting together with the gatekeeper and proxy
functionality of a BinTec X-Generation router with Software Release 6.2.1 or later. If you use X1000, X1200 or X3200 routers, the IPSec security solution and
the gatekeeper or proxy are not available at the same time.
Proceed as follows to make sure your router has the gatekeeper and proxy
functionality:
Router type
X1000, X1200, X3200
➤ Check which router type you are using.
For X1000, X1200 and X3200 routers:
➤ Check if your router is operated with the IPSec system software.
If you have Software Release 6.2.1 with IPSec:
➤ Install Software Release 6.2.1 without IPSec or purchase a BinTec X-Generation router that provides the IPSec and gatekeeper or proxy functionality
at the same time.
If you have Software Release 6.2.1 without IPSec, the gatekeeper and

router 1" and NetMeeting of "partner 2" is registered with the gatekeeper of
"BinTec router 2".
■ The two gatekeepers must "know" each other.
Procedure
The administrators of the BinTec routers activate the proxy to ensure that the
far side obtains access to their network.
Each administrator enters the desired data of "his" user in the USER TABLE of
his gatekeeper.
Each user enters in his NetMeeting only the alias and the gatekeeper with which
NetMeeting is to register. The actual registration takes place automatically.
To ensure that each user "knows" of the existence of the other, both administrators enter the gatekeeper of the "other end" as alternative gatekeeper in their
BinTec routers.
You can also use other H.323-capable endpoints instead of NetMeeting if they
are registered with the BinTec gatekeeper.

Making a Test Call
To check whether "partner 1" can communicate with "partner 2", "partner 1" can
set up a call to "partner 2".
As "partner 1" call Karl Kartoffel with the alias kk_netmeeting and the telephone
number 8901 (see figure B-6, page 71). You can enter the telephone number,
the user name or the alias for setting up the call.
You can also enter an address with the format [email protected], e.g.
[email protected]_kaka.provider.com. The part after the @ symbol is interpreted as
DynDNS name.

NetMeeting and DynDNS with Two BinTec Routers
Proceed as follows to set up a call to Karl Kartoffel:
Figure B-7: Setting up a call with NetMeeting
➤ Enter the desired telephone number in the NetMeeting you have already
started: 8901.
➤ You can also enter the user name, the alias or an address with the format
[email protected] as an alternative to the telephone number.
➤ Click the Place Call button to the right of the input field (i.e. the button with
the telephone symbol).
The call is set up.
Communication is possible in both directions. This means: it is immaterial if
"partner 1" calls "partner 2" or "partner 2" calls "partner 1", the call is always
set up without delay.

Configuration and Monitoring
If alternative gatekeepers are entered, the connection between the two routers
always remains open, as an open connection is necessary for the Time to
Live (sec) parameter (see table A-5, page 30).
We recommend that you use flat-rate Internet access.
