| 摘 要： | IP电话网关主要功能为连接传统电话网与IP网络，完成多路呼叫的信令协议和语音格式的转换。因此，在网关的实现过程中，会涉及到多路呼叫的资源分配与维护、多线程的处理与同步、呼叫状态的迁移与超时处理等问题。该文针对上述问题，提供了独特的实现方法，很好地解决了多路呼叫的资源占用、同步和超时等关键技术，有效地优化了网关系统性能。最后给出了网关指标中最重要的两个参数互通性与多路同时呼叫建立延时的测试结果及分析。

| Abstract: | The main function of gateways is to connect IP network and traditional phone system, and provide multi-call signaling exchanging and the conversion of voice formats. So there are some related problems to be solved, such as the allocation and management of multi calls, the synchronization of multi threads, the state transference and time-out processing. In this paper, key technologies in the realization is introduced, which are important to the stability and efficiency of the gateway. At last, the test of the Gateway is shown and the result is discussed . |
