At first, in this paper the background and basic principle of VoIP are introduced; the much popular VoIP technology based on H.323 protocol is studied; based on the function and main working process of IP telephone system, the principle of coding of compression and transfer technology of the real-time voice are analyzed; depended on the existed experimental environment, the program of voice part of PC to PC video telephone terminal based on LAN is designed and implemented; and the problems encountered during the design of program have been analyzed and solved.

本文首先介绍了IP电话的发展简史，IP电话技术原理；对目前最为流行的基于H.323协议的VoIP技术进行了研究；根据IP电话系统的功能和主要实现过程，分析实时语音压缩编码技术和传输技术原理；利用实验室现有的实验环境，设计并基本完成了一种基于局域网的PC to PC可视电话语音部分的编程；并对程序设计过程中所遇到的问题进行了分析和解决。

Founded at the beginning of that focus on communications products, digital voice record of research and development, down-to-earth, silently, through unremitting efforts, now the successful launch of the domestic first with independent intellectual property rights TDVR long recording telephone, telephone in the domestic terminal long time (more than 100 hours) the field of digital voice recording realize a zero breakthrough in China's professional-grade digital recording phone leader.
