基于软交换的SIP与H.323协议互通
摘要
SIP和H.323是下一代IP分组网上多媒体业务技术发展的两个方向
软交换可以同时支持这两种协议并实现两者的融合互通。在软交换网络的基础上
结合这两种协议的特征
本文简要介绍了SIP和H.323互通的实现过程和呼叫流程
并介绍了互通功能(IWF)单元在互通中的功能。
Abstract
SIP and H.323 are the two directions of development with the next generation IP network multimedia service technology. Softswitch can support these two protocols and realize the interworking between SIP and H.323. Based on the softswitch network
comparing the characteristic of these two protocols
it introduces the realization of intrerworking between SIP and H.323 and a typical call-flow
and analyzes the function of inter-working (IWF) unit in interworking.
