An Overview of the Cisco Unified IP Phone
The Cisco Unified IP Phone 7906G and 7911G provide voice communication over an Internet Protocol
(IP) network. It functions much like a standard digital business telephone, allowing you to place and
receive phone calls and to access features such as mute, hold, transfer, and speed dial. In addition,
because the phone is connected to your data network, it offers enhanced productivity features, including
access to network information, XML applications, and customizeable features.
A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones
encode G.711a, G.711u, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711u, G.722, iLBC,
G.729, G.729a, G.729b, and G.729ab. These phones also support uncompressed wideband (16 bits, 16
kHz) audio.
