Distributed Gateway Interworking with SIP/H.323

摘要

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 tot he 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.
