摘要
介绍了一种具有广泛应用前景、小巧而快速的开源S IP协议栈-O S IP.在详细分析O S IP协议栈的结构、特点及其运行机制的基础上,给出了基于O S IP协议栈的S IP用户代理(UA)方案.此方案利用S IP以及SDP等开放协议,完成了通讯双方实时的交互,既可以扩展到即时通讯(IM)方面,也可以作为视频会议实现的基础,具有较好的兼容性.
The OSIP library is an implement of SIP protocol. It is little in size and code and thus could be very useful at developing devices based on SIP. This paper analyzes the structure, feature and use of OSIP library in detail, At the end of this paper,we discuss how to use OSIP library to design and implement user agent of SIP phone. This type of user agent is implemented based on open protocol including SIP, SDP in order to fulfill instant information exchange. It can be applied not only to IM, but to video conference, Meanwhile it is more compatible,
