自己动手写的sip协议栈，SIP（Session Initiation Protocal）称为会话初始化协议，是由IETF（Internet Engineering Task Force）组织于1999年提出的一个基于IP网络中实现实时通信应用的一种信令协议。-Do-It-Yourself wrote sip protocol stack, SIP (Session Initiation Protocal) known as the Session Initiation Protocol is the IETF (Internet Engineering Task Force) organization in 1999 as a network-based real-time IP communications applications a letter the agreement.

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

H.323协议系列的一部分，用于会话的控制，开发H.323产品必须要懂H.225,这是2000年的版本，对应H.323 V4-H.323 part of the series for the conversational control, product development H.323 H.225 must understand that this is the 2000 version, corresponding H.323 V4
