South African Telecommunications Networks & Applications Conference (SATNAC 2001), pp. 689–693. Wild Coast Sun, Eastern Cape, South Africa0-620-27769-6http://hdl.handle.net/10566/465The Session Initiation Protocol and H.323 dominate the Voice over IP world. These signaling protocols are responsible for call setup and call tear down by IP telephony solutions. This project analyses and discusses the underlying H.323 and SIP interoperability issues and intends to build a scalable solution for the interoperability of these protocols. The gateway maps the call sequences between the two protocols. A test scenario establishes a barrage of call setup and tear down requests to test the scalability of any H.323/SIP interoperability solution.enCopyright Telkom.
