基于SIP与MGCP协议的VOIP终端互通的研究

Interworking between VOIP terminals based on MGCP and SIP protocol

在当前软交换网络中,VOIP终端应用的比较普遍,其中MGCP和SIP终端尤为突出。由于二者均可实现语音、多媒体等通信业务,因此关于不同协议间的互通实现在软交换网中有着很重要的现实意义。从终端出发,由终端讨论到协议和各种呼叫流程,继而对不同协议间的通信进行了分析,并对终端间的互通进行了模拟。

It＇ s typic and extensive application for VOIP terminals in softswitch network. SIP and MGCP have played very important roles in NGN. They provide communication services via packet switching network, such as speech and multimedia etc. It＇s important and actual signification to study the interworking in softswitch. This article respectively analyzes the call flow between the different terminals , furthermore researches on the kinds of communication and stimulates the implementation of interworking between MGCP and SIP terminals.
