ISO/IEC 18056:2010

Information technology — Telecommunications and information exchange between systems — XML protocol for Computer Supported Telecommunications Applications (CSTA) Phase III

ISO/IEC 18056:2010 specifies an XML protocol for the services defined in ISO/IEC 18051. It provides an alternative protocol to the ASN.1-based protocol specified in ISO/IEC 18052. In addition to the CSTA-specific protocol details, it describes the concepts underlying the request/response model, application association, notation and service, and describes the template used in ISO/IEC 18056:2010. It also specifies the PICS for ISO/IEC 18056:2010 and provides examples of CSTA XML encodings.
