摘　　要：详细地描述了VoIP(Voice over Internet Protocol)的SIP呼叫在三网合一交换机中实现过程,讨论了SIP呼叫的处理流程,用开源的oSIP协议栈实现SIP呼叫。包括注册,电话号码处理,以及接通和挂断处理。从原理上描述了SIP呼叫在三网合一交换机中的具体实现。分析了SIP协议栈的运行机制,设计了将SIP协议栈移植到三网合一交换机,并以此为基础开发基于SIP呼叫的实现方案。The achievement of SIP calling of VolP （Voice over Interact Protocol） in tri-ptay switch is presented in detail, the processing flow of SIP calling is discussed and the GPL oSIP protocol stack is applied to achieve SIP calling, including registration, phone number processing, and connecting as well as hang-up process. The detail achievement of SIP calling in tri-play switch was described from principle. The operating mechanism of SIP protocol stack was analyzed in detail and the SIP protocol stack was successfully transplanted to tri-play switch. On this basis, the SIP calling-based achievement scheme was developed.
