Phone Overview
The Cisco Unified IP Phone 7975G, 7971G-GE (gigabit Ethernet version), 7970G, 7965G, and 7945G is a
full-featured telephone that provides voice communication over an Internet Protocol (IP) network. These IP
phones function much like digital business phones and allow you 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 connect to your data network, they offer enhanced IP telephony features, such as access
to network information and services and customizable 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 7975G, 7971G-GE, 7970G, 7965G, and 7945G provides a color screen (touchscreen
for the 7975G, 7971G-GE, and the 7970G), support for line or speed dial numbers, context-sensitive online
help for buttons and features, and a variety of other sophisticated functions.
A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode
G.711a, G.711mu, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711mu, G.722, G.729, G729a,
G.729b, G.729ab, and iLBC. These phones also support uncompressed wideband (16 bits, 16 kHz) audio.
Use of a cell, mobile, or GSM phone or two-way radio in close proximity to a Cisco Unified IP Phone
might cause interference. For more information, see the manufacturer documentation of the interfering
device.
