Cisco Unified IP Phone 7960G/7940G Administration Guide for Cisco Unified Communications Manager 7.0 (SIP)
OL-15499-01
Chapter 1 An Overview of the Cisco Unified IP Phone
What Features are Supported on the Cisco Unified IP Phone 7960G and 7940G?
Feature Overview
Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and
transferring, redialing, speed dialing, and voice messaging system access. Cisco
Unified IP phones also
provide a variety of other features. For an overview of the telephony features that the
Cisco
Unified IP Phone supports and for tips on configuring them, see the “Telephony Features
Available for the Cisco Unified IP Phone” section on page 5-2.
As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access
Cisco
Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer
settings to configure on a phone, but if your network requires it, you can manually configure an IP
address, TFTP server, and subnet mask. For instructions on configuring the network settings on the
Cisco
Unified IP Phones, see Chapter 4, “Configuring Settings on the Cisco Unified IP Phone.
The Cisco Unified IP Phone can interact with other services and devices on your IP network to provide
enhanced functionality. For example, you can integrate the Cisco
Unified IP Phones with the corporate
Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for
co-worker contact information directly from their IP phones. You can also use XML to enable users to
access information such as weather, stocks, quote of the day, and other web-based information. For
information about configuring such services, see the
“Configuring Corporate and Personal Directories”
section on page 5-4 and the “Setting Up Services” section on page 5-6.
Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status
information from it directly. This information can assist you with troubleshooting any problems users
might encounter when using their IP phones. See
Chapter 6, “Viewing Status, Statistics, and Firmware
Information on the Cisco Unified IP Phone, for more information.

Configuring Telephony Features
You can modify additional settings for the Cisco Unified IP Phone from the

services, and to modify phone button templates, among other tasks. See the
“Telephony Features
Available for the Cisco Unified IP Phone” section on page 5-2 and refer to the
Cisco Unified Communications Manager documentation for additional information.
For more information about the Cisco Unified Communications Manager Administration application,
