An Overview of the Cisco Unified IP Phone
The Cisco Unified IP Phone 7962G and 7942G are full-feature telephones that provide voice
communication over an Internet Protocol (IP) network. The Cisco Unified IP Phone functions much like
a digital business phone, 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 the phone is connected to
your data network, it offers enhanced IP telephony features, including access to network information and
services, and customizeable features and services. The phone also supports 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.
