摘要
SIP协议因其小巧、灵活成为了现代多媒体通信的主流协议之一,有着广泛的应用前景。首先对SIP协议进行了简单的综述,然后按消息处理,事务状态机和消息传输三大模块对SIP用户代理的实现方法进行了详尽的说明,同时选用miniSipServer服务器对用户代理注册及呼叫连通功能进行了测试,最后证明实现方法是有效的。
SIP becomes one of modern multimedia mainstream protocols because of its compactness and flexibility and thus has an extensive application prospect. This paper briefly sums up the SIP protocol, and then based on the three modules including message, transation, and message transport, presents the implementation method of SIP UA. Meanwhile, miniSipServer is chosen to test the registration function of UA and the connectivity of the call. Experiment indicates that the implementation method is feasible and efficient.
