Projekta Nr.ISO/IEC TR 22767:2005
Nosaukums<p>ISO/IEC TR 22767:2005 describes how CSTA can be used to provide a subset of CSTA call control functionality, called first party call control, for Session Initiation Protocol (SIP) user agents. The term uaCSTA (for user agent CSTA) refers to transporting ECMA-323 (CSTA XML) messages over a SIP session.</p> <p>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.</p> <p>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.</p> <p>uaCSTA leverages SIP mechanisms to provide a highly featured, robust, and extensible set of features to support applications in the Enterprise environment.</p> <p>uaCSTA can be implemented by several different types of SIP user agents:</p> <ul><li>directly by a SIP user agent on a SIP phone,</li><li>uaCSTA can also be implemented by a SIP B2BUA to augment 3PCC functionality, and</li><li>by a proxy server that is front-ending a PBX.</li></ul>
