基于eXosip协议栈的SIP电话的研究与实现

Research and Implementation of SIP Phone Based on eXosip Protocol Stack

SIP协议是嵌入式终端的理想信令协议,而SIP协议栈在系统设计中显得尤为重要。eXosip协议栈实现了作为单个SIP终端的大部分功能,且结构简单小巧、灵活性强、可扩展性强,更加的智能化。简单介绍了oSIP协议栈及eXosip协议栈的基本内容,并在此基础上详细介绍了嵌入式SIP电话的硬件及软件设计过程,并进行试验得到了预期的效果。

SIP is the ideal signaling protocol of embedded terminal,and SIP protocol stack is especially important in the system designing.eXosip protocol stack realized most of the functions as the single SIP terminal,and the structure is small and exquisite,had strong flexibility and scalability,and is more intelligent.This paper simply introduces the basic content of oSlP and eXosip protocol stack,and on the basis,the hardware and software designing process of embedded SIP phone;and the experiment is done,and got the desired results.
