()
摘要:
首先介绍了SIP协议,包括其功能、系统基本组成、消息格式,然后设计了软件的三大模块:用户界面模块、SIP UA模块、语音通信模块,并使用编程工具V isual C 6.0、SIP协议栈OSIP、EXOSIP及RTP协议栈W inRTP实现了该软电话。测试结果表明,该SIP软电话在局域网环境下具有良好的通话质量。

()
Abstract:
This paper designs and realizes a soft phone based on SIP protocol and Windows environment.It introduces SIP protocol first,including its function,basic system composition and message format,then designs three modules of the software: user interface module,SIP UA module and voice communication module,and realizes the soft phone by using programming tool Visual C 6.0,SIP stack OSIP and EXOSIP,RTP stack WinRTP.The test in local area network environment shows that the SIP soft phone has good voice quality.
