| 摘 要： | 在SIP网络出现之前,以IP网络为传输系统的H.323网络已得到广泛应用,因此,必须考虑SIP网络和H.323网络的互联问题.通过分析两个协议互通过程中需要解决的地址解析和映射、消息映射、媒体能力协商等问题,并深入研究它们的状态图,然后分别以SIP向H.323终端发起呼叫以及H.323向SIP终端发起呼叫为模型,模拟两协议的互通实现,经实践证明此方案是合理可行的.

| Abstract: | Before the SIP network appeared,the H.323 networks which transmitted by IP network system has been widely applied.Therefore,must take into the interworking between SIP networks and the H.323 network.Through analysis the problem such as address resolving and mapping,information mapping,the negotiation of media capability which are produced in the process of the two protocol interworking,and in-depth study of their state diagram,then,respectively launched a call model by SIP to H.323 terminals and H.323 to SIP terminals,simulating the interworking of two protocol,which proved this scheme is reasonable and practicable. |
