An approach of integrating SIP in converged multimodal/multimedia communication services

In this paper, we present an approach of integrating SIP (session initiation protocol) in converged multimodal/multimedia communication services. An architecture of multimedia technology integration platform (MTIP) in converged communication environment with SIP is described. This distributed dialogue system infrastructure is based on the concept of dialogue system and web convergence, where applications and communication services can be enabled through task specific markup languages based on XML. The loosely coupled open architecture in our approach is highly extensible. It allows an easy extension to include SIP in converged multimodal/multimedia communication services. The concept and structure of VoIPTeleServer is described, which interfaces to the VoIP world and works as a broker between the SIP environment and MTIP to deliver converged communication services. A prototype of VoIPTeleServer was implemented, and services and applications based on SIP and MTIP convergence are constructed.
