Avaya Communication Manager supports SIP endpoints, including the Avaya 4602 SIP Telephone and Avaya IP Softphone Release 5. In addition to its IP telephony capabilities, IP Softphone R5 also includes Instant Messaging (IM) client software, which is a SIP-enabled application that connects to the Avaya Converged Communication Server for IM control. By means of having SIP-enabled endpoints managed by Communication Manager, many features can be extended to these endpoints. The servers (S8300, S8500 or S8700-series) function in four ways:

●As Plain Old Telephone Service (POTS) gateways

●As support for name and number delivery between and among the various non-SIP endpoints supported by Communication Manager

For instance, analog, DCP (Digital Communications Protocol) or H.323 stations, and analog, digital or IP (internet protocol) trunks.

●As support for new SIP-enabled endpoints, such as the Avaya 4602 SIP telephone

●As a telephony feature server to SIP endpoints

The set of features supported by SIP itself is augmented by those supported by Communication Manager.
