SIP终端语音聊天的设计与实现

The Design and Implementation of SIP Terminal Voice Chat

SIP协议是多媒体通信网的控制协议,在分组交换网中,它提供基本的呼叫控制,负责建立、修改和终止多媒体(话音、数据、视频等)会话等应用。概述了SIP终端软件的设计思想,并详细介绍了SIP终端软件中语音聊天功能的关键技术,从宏观和微观2个角度阐述了语音聊天功能的实现过程,构造了系统测试环境。SIP终端软件实现了语音聊天功能,具有良好的性能。

The session initiation protocol （SIP） is the multi - media network eontrol protocol,designed to provide basic call control and to establish, modify and terminate multimedia （voice, data, video and so on）sessions and so on, in a packet - switched network. The paper has outlined design idea of the SIP terminal software, introduced in detail the key techniques for voice chat function, elaborated from both macroscopic and the microscopic viewpoints the implementation process of voice chat function, and established the system test environment. The SIP terminal software realizes the voice chat function and has good performance.
