一种基于TAPI的IP电话软件网关的设计与实现

IP电话的产生是计算机网络发展的必然产物,在其发展到一定规模后必然要求与原有的PSTN网的联合,在这个过程中就有一个模拟数据与数据报文之间相互转换的问题,IP电话网关就是它们之间的桥梁.本文介绍了TAPI接口,给出了利用Microsoft TAPI3.0开发一个软件IP电话网关系统的具体实现及其成功的应用实例.

Design and Implementation of Software Gateway for IP Phone Based on TAPI

The generation of IP phone is the necessary result of computer network's development and as it has grown to a certain degree, a demand of combining IP network with existing PSTN network is growing, and so, in the process of realizing it, people will face a problem that converting the form of data between analog signals and digital signals, and the gateway of IP phone is the bridge between them. This paper introduces the TAPI interface, then gives the implementation of an software gateway of IP phone in detail by using Microsoft TAPI3.0 and an example of its successful application is presented at last.
