An Overview of the Cisco
Unified IP Phone
The Cisco Unified IP Phone 7970 Series are full-featured telephones that provide
voice communication over an Internet Protocol (IP) network. They function much
like digital business phones, 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 Cisco Unified IP Phones are connected to your data network,
they offer enhanced IP telephony features, including access to network
information and services, and customizeable features and services. The phones
also support security features that include file authentication, device
authentication, signaling encryption, and media encryption.
The Cisco Unified IP Phone 7970 Series provides a color touchscreen, support for
up to eight line or speed dial numbers, context-sensitive online help for buttons
and features, and a variety of other sophisticated functions.
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, and decodes all
variants of G.711 and G.729. The phone also supports wideband (16bits, 16kHz)
audio.
