Real-time service composition is provided by a Session Initiation Protocol (SIP) transport binding for Simple Object Access Protocol (SOAP) messages. A SOAP Action header and SOAP envelope can be included in a SIP message to identify a requested service. The SIP message recipient (206) can parse out the SOAP envelope and forward same to a corresponding Web Service (210, 212). An intermediary node (600), including a SIP Proxy, can evaluate incoming SIP/SOAP messages and provide requested services to which they have access. Service discovery and subscription are facilitated by adding Universal Description, Discovery and Integration (UDDI) services requests and responses. |
