An Overview of the Cisco Unified IP Phone
The Cisco Unified IP Phone 7965G and 7945G are full-featured telephones that provide voice
communication over an Internet Protocol (IP) network. These phones 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.
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.711u, G.722, iLBC,
G.729, G729a, G729b, and G729ab. These phones also support uncompressed wideband (16bits, 16kHz)
audio.
