The latest Distributed Gateway (DG) architecture based on VoIP and its internal Protocol-Media Gateway Control Protocol(MGCP) are presented. A framework for Distributed Gateway(DG) interworking with H. 323 /SIP is described. Moreover, the revised Distributed Gateway architecture, namely, adding components to DG for interworking with H. 323 /SIP is discussed.%在IP承载语音(VoIP)和媒体网关控制协议(MGCP)的基础上,提出了分布武网关(DG)体系结构,给出与H.323/SIP交互作用的分布式网关的一种框架.并且论述了改进的分布式网关体系结构,也就是与H.323/SIP交互作用的分布武网关的扩展部件.
