软交换中IP录音的设计

Design on IP Recording in Softswitch

随着软交换网络的不断发展和大规模应用,如何在其上实现录音功能,成为研究的重要课题。分析了传统网协(IP)录音实现方案的原理和缺陷。依据软交换网络的特点,提出了软交换与IP录音服务器之间的接口设计。采用媒体旁路路由的方法,讨论了IP录音在软交换网络中的设计方案,描述了录音的运行流程。利用计算机模拟IP录音服务器的功能,对设计进行了测试,测试结果证明了设计的可行性。

With the development and large-scale application of soft.switch, the realization of Internet Protocol （IP） recording in softswitch becomes a significant issue. The principle and limitation of tradition realization for IP recording is firstly analyzed. According to the features of softswitch network, the interface design between softswitch and media server for IP recording is presented. This paper discusses the design of IP recording in the softswitch with the method of routing media of the target device to the media server and describes the operational flow of IP recording. Finally, the test for the design is done with computer acting as media server and the result proves that the design is feasible.
