An Overview of the Cisco Unified IP
Phone
The Cisco Unified IP Phone provides voice communication over an Internet
Protocol (IP) network. It functions much like a traditional analog 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 IP telephony features, including access to
network information and customizeable features.
This manual describes the Cisco Unified IP Phone 7905G and 7912G. The Cisco
Unified IP Phone 7905G and 7912G include softkeys and an LCD screen. The
Cisco Unified IP Phone 7912G adds an internal Ethernet switch.
These phones encode G.711a, G.711u, G.729a, G.729ab, and decode all variants
of G.711 and G.729.
A Cisco Unified IP Phone must be configured and managed like other network
devices.
