The brief description and comparison are given to the following two signaling protocol standards that are currently used in Internet: ITU T Recommendation H .323 and IETF Session Initiation Protocol ( SIP ). After the introduction to the latest Distributed Gateway ( DG ) architecture and its internal protocol Media Gateway Control Protocol ( MGCP ), we describe a framework for DG interworking with H.323/SIP . Other topics, such as address translation, relocation of signaling transport protocol architecture and adding components to DG for interworking with H.323/SIP , are also addressed.
