分网络传输部分、音频输入、音频输出、视频输入、视频输出、音频视频压缩、音频波形显示、界面。共创建个线程，音频输入线程、音频输出线程（这两个有WINAPI隐式创建）、音频视频压缩传送线程和主线程。因为音频的采样率比视频采样率高得多，这里的音频的采样率为8000Hz而视频仅为20左右，所以从宏观来看，音频是连续的，而视频是非连续的，这也就是无须为视频输入输出创建独立线程的原因。- Minute network transmission part, audio frequency input, audio frequency output, video input, video output, audio frequency video frequency compression, audio frequency profile demonstration, contact surface. Altogether founds the line regulation, the audio frequency input line regulation, the audio frequency output line regulation (these two has WINAPI to hide type to found), the audio frequency video frequency compression transmission line regulation and the master line regulation. Because the audio frequency sampling rate is much higher than the video frequency sampling rate, here audio frequency sampling rate is 8000Hz but the video frequency is only about 20, therefore from macroscopic looked, the audio frequency is continual, but video frequency right and wrong continual, this also

中文版SIP协议。包括RFC2327(sdp)，RFC3263(sip)，RFC3621(sip)，RFC3372(sip)，其中3261协议包括注册部分是完全版-Chinese version of SIP. Including RFC2327 (sdp) and RFC3263 (sip), RFC3621 (sip), RFC3372 (SIP), including the 3261 agreement is fully registered version

SIP的开发包，非常好用-SIP development kits, very handy

eXosip is a GPL library that extend the capability of the oSIP library. It aims to implement a simple high layer API to control the SIP for sessions establishements and common extensions.
