Adapting H.323 terminals in a service-oriented collaboration system

The Global Multimedia Collaboration System is designed to bridge H.323, Session Initiation Protocol, Access Grid clients, and 2.SG/3G cellular phones in audio-visual collaborations. One of its key components is the H.323 gateway, which lets H.323 terminals interact with other clients, providing complete conferencing control services. This system is designed to help scientists and students who have access only to H.323 and SIP endpoints or cellular phones with scientific collaboration in the high-end Access Grid environment.
