H.323网关实现中的难点分析及解决方案

Technologies Analysis and Realization in the H.323 Stack of the VoIP Gateway

VoIP普遍采用H.323体系标准,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,以及协议栈版本前后兼容等问题,这些问题的处理好坏对网关的系统效率以及互通性方面会有很大的影响。文章针对上述问题进行分析,提出了自己独特的解决方法,有效地优化了网关系统性能,并给出了网关的测试结果。

Nowadays H.323 architecture is used in VoIP system popularly. During the realization of the H.323 Gateway,there are many things to be solved,such as the allocation and management of multi calls,the synchronization of multi threads,the state transition and time out processing and even compatibility of the H.323 stack with other end points and other versions. They are important to the stability,compatibility and efficiency of the Gateway. In this paper,the related technologies are discussed and presented. At last,the result is given.
