Understanding The Cisco Unified Ip Phones 7975G, 7971G-Ge, 7970G, 7965G, And 7945G; What Networking Protocols Are Used? - Cisco CP-7970G Administration Manual

An Overview of the Cisco Unified IP Phone
The Cisco Unified IP Phone 7975G, 7971G-GE (gigabit Ethernet version), 7970G, 7965G, and 7945G
are full-featured telephones that provide voice communication over an Internet Protocol (IP) network.
They function much like digital business phones, allowing 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 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 7975G, 7971G-GE, 7970G, 7965G, and 7945G each provide 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.711µ, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711µ, G722, iLBC, and
G.729, G729a, G.729b, and G.729ab. These phones also support uncompressed wideband (16bits,
16kHz) audio.
