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. These phones encodes G.711a, G.711µ, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711µ, G722, iLBC, and G.729, G729a, G.729b, and G.729ab. These phones also support uncompressed wideband (16bits, 16kHz) audio.
