An Overview of the
Cisco Unified IP Phone
The Cisco Unified IP Phones 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.
The Cisco Unified IP Phone, like other network devices, must be configured and
managed. The phone encodes G.711a, G.711µ, G.729a, G.729ab, G.728/iLBC,
and decodes all variants of G.711, G.728/iLBC, and G.729. The phone also
supports wideband (16bits, 16kHz) audio.
