TC32-TG11 - Computer Supported Telecommunications Applications (CSTA)

Scope - Programme of work - Activities


Develop and refine the Computer Supported Telecommunications (CSTA) standard. CSTA specifies an Applications Interface and Protocols for monitoring and controlling calls and devices in a communications network.

These calls and devices may support various media and can reside in various network environments such as IP, Switched Circuit Networks and mobile networks. CSTA however, abstracts various details of underlying signalling protocols (e.g. SIP/H.323) and networks for the applications.

Programme of work:

  1. To study aspects of CSTA, with special focus to:
    • Improve CSTA and SIP interoperability
    • Improve CSTA and Web interoperability (leverage CSTA XML usage with e.g. WSDL/UDDI)
    • Provide conferencing enhancements for collaboration applications
    • Provide finer grained media control
    • Improve support for non-voice media

  2. To produce Technical Reports illustrating how CSTA fits into various environments such as in call/contact centres, voice-browser and Internet environments.

  3. To produce Standards specifying the services, functional entities and protocols required enabling CSTA operation in a variety of environments.

  4. To liaise with organisations studying similar topics including groups working within ITU-T and ISO/IEC JTC 1/SC 6, IETF, W3C and ETSI, to promote unified international standards.
