Preparing to Install the Cisco Unified
IP Phone on Your Network
Cisco Unified IP Phones enable you to communicate using voice over a data
network. To provide this capability, the IP Phones depend upon and interact with
several other key Cisco Unified IP Telephony components, including
Cisco Unified Communications Manager.
This chapter focuses on the interactions between the Cisco Unified IP Phone
7961G/7961G-GE and 7941G/7941G-GE and Cisco Unified Communications
Manager, DNS and DHCP servers, TFTP servers, and switches. It also describes
options for powering phones.

Cisco Unified Communications Manager
Cisco Unified Communications Manager is an open and industry-standard call
processing system. Cisco Unified Communications Manager software sets up and
tears down calls between phones, integrating traditional PBX functionality with
the corporate IP network. Cisco Unified Communications Manager manages the
components of the IP telephony system—the phones, the access gateways, and the
resources necessary for such features as call conferencing and route planning.
Cisco Unified Communications Manager also provides:

Understanding How the Cisco Unified IP Phone Interacts with the
VLAN
The Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE have an
internal Ethernet switch, enabling forwarding of packets to the phone, and to the
access port and the network port on the back of the phone.
If a computer is connected to the access port, the computer and the phone share
the same physical link to the switch and share the same port on the switch. This
shared physical link has the following implications for the VLAN configuration
on the network:
•
The current VLANs might be configured on an IP subnet basis. However,
additional IP addresses might not be available to assign the phone to the same
subnet as other devices connected to the same port.
•
Data traffic present on the VLAN supporting phones might reduce the quality
of Voice-over-IP traffic.
•
Network security may indicate a need to isolate the VLAN voice traffic from
the VLAN data traffic.

Chapter 2
Providing Power to the Cisco Unified IP Phone
Preparing to Install the Cisco Unified IP Phone on Your Network
You can resolve these issues by isolating the voice traffic onto a separate VLAN.
The switch port that the phone is connected to would be configured to have
separate VLANs for carrying:
•
Voice traffic to and from the IP phone (auxiliary VLAN on the Cisco Catalyst
6000 series, for example)
•
Data traffic to and from the PC connected to the switch through the access
port of the IP phone (native VLAN)
Isolating the phones on a separate, auxiliary VLAN increases the quality of the
voice traffic and allows a large number of phones to be added to an existing
network where there are not enough IP addresses for each phone.
For more information, refer to the documentation included with a Cisco switch.

Understanding Phone Configuration Files
Configuration files for a phone are stored on the TFTP server and define
parameters for connecting to Cisco Unified Communications Manager. In
general, any time you make a change in Cisco Unified Communications Manager
that requires the phone to be reset, a change is made to the phone’s configuration
file automatically.
Configuration files also contain information about which image load the phone
should be running. If this image load differs from the one currently loaded on a
phone, the phone contacts the TFTP server to request the required load files.
(These files are digitally signed to ensure the authenticity of the files’ source.)
In addition, if the device security mode in the configuration file is set to
Authenticated and the CTL file on the phone has a valid certificate for
Cisco Unified Communications Manager, the phone establishes a TLS connection
to Cisco Unified Communications Manager. Otherwise, the phone establishes a
TCP connection. For SIP phones, a TLS connection requires that the transport

Understanding Phone Configuration Files
protocol in the phone configuration file be set to TLS, which corresponds to the
transport type in the SIP Security Profile in Cisco Unified Communications
Manager.
Note
If the device security mode in the configuration file is set to Authenticated or
Encrypted, but the phone has not received a CTL file, the phone will continuously
try to obtain a CTL file so that it can register securely.
If you configure security-related settings in Cisco Unified Communications
Manager Administration, the phone configuration file will contain sensitive
information. To ensure the privacy of a configuration file, you must configure it
for encryption. For detailed information, refer to the “Configuring Encrypted
Phone Configuration Files” chapter in Cisco Unified Communications Manager
Security Guide.A phone requests a configuration file whenever it resets and
registers with Cisco Unified Communications Manager.
A phone accesses a default configuration file named XmlDefault.cnf.xml from the
TFTP server when the following conditions exist:
•
You have enabled auto-registration in Cisco Unified Communications
Manager
•
The phone has not been added to the Cisco Unified Communications
Manager Database
•
The phone is registering for the first time
If auto registration is not enabled and the phone has not been added to the
Cisco Unified Communications Manager Database, the phone registration request
will be rejected. In this case, the phone will reset and attempt to register
repeatedly.
If the phone has registered before, the phone will access the configuration file
named SEPmac_address.cnf.xml, where mac_address is the MAC address of the
phone.
The TFTP server generates these SIP configuration files:
•
SIP IP Phone:
– For unsigned and unencrypted files—SEP<mac>.cnf.xml
– For signed files—SEP<mac>.cnf.xml.sgn
– For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn
