摘要
SIP协议是NGN的重要协议．在对SIP协议的基本原理、组成和功能进行简要介绍其础上，对SIP协议的开源协议栈Osip和eXosip做了进一步分析．并根据软电话建立的基本原理，在Linux环境下用C语言设计了基于eXosip的软电话．可供eXosip协议栈应用者和软电话开发者参考．
SIP is one of the important protocals in NGN. In this paper, the basic principle of SIP, composition and function are introduced briefly, further analyzing the Osip and eXosip of the open-souree SIP protocol stack. Accordings to the implementation principle in softphone, a softphone based on eXosip protocol stack was designed by the C program code in the Linux OS, and was provided to eXosip protocol stack users and softphone developers for reference.
