THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT
NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT
ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR
THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION
PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO
LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate
radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television
reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in
part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation.
However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class
A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct
any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco
equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by
using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television
or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

Preface
Overview
Cisco Unified IP Phone 7931G Administration Guide for Cisco Unified
Communications Manager 6.0 provides the information you need to understand,
install, configure, manage, and troubleshoot the Cisco Unified IP Phone 7931G
on a Voice-over-IP (VoIP) network.
Because of the complexity of an IP telephony network, this guide does not provide
complete and detailed information for procedures that you need to perform in
Cisco Unified Communications Manager or other network devices.
Audience
Network engineers, system administrators, or telecom engineers should review
this guide to learn the steps required to properly set up the Cisco Unified IP Phone
7931G on the network.
The tasks described are administration-level tasks and are not intended for
end-users of the phones. Many of the tasks involve configuring network settings
and affect the ability of the phone to function in the network.
Because of the close interaction between the Cisco Unified IP Phone and
Cisco Unified Communications Manager, many of the tasks in this manual
require familiarity with Cisco Unified Communications Manager.

CHAPTER
1
An Overview of the Cisco
Unified IP Phone
The Cisco Unified IP Phone 7931G is a full-featured telephone that provides
voice communication over an Internet Protocol (IP) network. Designed for users
who are familiar with traditional key sets, they function much like digital business
phones, allowing users to place and receive phone calls and to access features
such as mute, hold, transfer, speed dial, call forward, and more. In addition,
because Cisco Unified IP Phones are connected to your data network, they offer
enhanced IP telephony features, including access to network information and
services, and customizeable features and services. The phones also support
security features that include file authentication, device authentication, signaling
encryption, and media encryption.
The Cisco Unified IP Phone 7931G provides a pixel-based backlit display, 24
configurable line buttons, and a variety of other functions to meet the
communications needs of business with moderate telephone traffic and specific
call requirements. Dedicated hold, redial, and transfer keys facilitate call
handling. Illuminated mute and speakerphone keys give a clear indication of
speaker status.
The Cisco Unified IP Phone, like other network devices, must be configured and
managed. The phone encodes G.711a, G.711u, G.729a, G.729ab, G.728/iLBC,
and decodes all variants of G.711, G.728/iLBC, and G.729. The phone also
supports (16-bit, 16-kHz) wideband audio.
