1 C H A P T E R 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.
