摘　　要：随着软交换技术的发展，软交换教学实验系统成了高校通信专业教学的重要建设内容。SIP（SessionInitiationProtoc01）协议是软交换中的会话控制协议，在软交换中起着极其重要的作用。目前出现的软交换教学实验系统存在着功能不易扩充的问题，针对这一问题，本文提出采用DLL（DynamicLinkEibrary）功能插件的方法实现SIP协议的功能。这种实现方法提高了系统的功能扩充性。通过测试，验证了该方法的可靠可行性，该方法已经在软交换教学实验系统中得到了应用。Along with the development of softswitch technology, the softswitch experimental teaching system has beeome the important content of teaching in communication speciality in universities. SIP protocol is the conversation eontrol protocol of the softswitch, playing an important role. Currently the softswitch experimental teaching system is not easy to expand functions and in order to solve this problem, this paper puts forward the method of DLL function plugin to realize the function of SIP protocol. This method improves the function expansion of system. The test shows that this method is reliable and feasible. This method has been applied in the softswitch experimental teaching system.
