摘要
文中对SIP协议的基本原理、组成和功能进行了介绍。对SIP协议的开源协议栈Osip和eXosip做了进一步分析,并将Osip和eXosip协议栈移植到μc/os操作系统中作为SIP客户端,实现了μc/os系统下SIP客户端中多用户向SIP服务器注册、响应SIP服务器对客户端任意用户的呼叫请求的功能。
SIP is one of the important protocols in NGN(Next-Generation Network).In this paper,the basic principle,composition and function of SIP are introduced briefly.A detailed analysis is made of the Osip and eXosip of the open-source SIP protocol stack,and the Osip and eXosip are transplanted onto the μc/os system as a SIP client.A SIP Client based on μc/os OS is designed in which the multiuser can register on the SIP server,and the SIP Client can answer calls from any user on the SIP server.
