Information technology -- Telecommunications and information exchange between systems -- Using CSTA for SIP phone user agents (uaCSTA)
SIP is a control (signalling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences.
CSTA standardizes a very powerful and flexible set of application services to observe and control voice and non-voice media calls as well as control and observe non-call related features.
uaCSTA leverages SIP mechanisms to provide a highly featured, robust, and extensible set of features to support applications in the Enterprise environment.
uaCSTA can be implemented by several different types of SIP user agents:
- directly by a SIP user agent on a SIP phone,
- uaCSTA can also be implemented by a SIP B2BUA to augment 3PCC functionality, and
- by a proxy server that is front-ending a PBX.
