很好的h323库，开放源代码，有开发指南

oSIP开发者手册，有对sip的解释和对osip的详细描述-oSIP developer manual, have to sip the interpretation and a detailed description of oSIP

g726算法c源码,应用于语音压缩，如voip应用-algorithm source code for voice compression, as voip application

简单的局域网中用的IP电话程序-A simple IP phone program which used in LAN network

openh323 通用库，用到pwlib -Universal library for openh323, using pwlib

H.263编解码器实例，完成时间比较早，但对于初学者仍具有很大的参考价值。-H.263 codec example, the completion time relatively early for beginners but still have great reference value.

视频压缩编解码ITU h.263源代码.经典的视频会议和远程监控算法.- The video frequency compression arranges decodes ITU the h.263 source code Classical video frequency conference and long-distance monitoring algorithm

vc编写的sip代理服务器,无需其他的库，直接编译-vc prepared sip proxy server, no additional library is directly compiled

需要的可以用到 ！专业性强！-needs can be used! Professional strong!

G726局域网语音通话程序和源代码 这是使用G726语音压缩（16kbps）和RTP进行传输的程序，因为我没有带WIFI的PPC，所以每个程序都是单独测试的，PC端和PPC端分别都工作正常。 G726编解码算法来自OpenH323.传输使用的RTP可以在RTP程序中找到讲解，这个程序主要是G726的函数。将整个 G726封装为g726_Encode和g726_Decode两个函数，参数为压缩和解压数据存储的地址指针，可以将960字节压缩到120字节和将 120字节解压为960字节。这里G726使用的时候，音频设置为8kHz，16位量化，单声道。 使用方法很简单，只用两端各自输入对方的IP，然后按下“开始对话”，就可以进行语音通信了。 PPC端的运行比较稳定，已经进行了自收自发近一个小时连续工作的测试，非常稳定，话音清晰。-G726 LAN voice calls procedures and the source code is the use of voice compression G726 (16kbps ) and RTP for the transmission process, because I did not bring WIFI the PPC, there are separate procedures for each test, PC- and PPC-were all normal work. G726 codec algorithm from the OpenH323. RTP transmission can be used in the process to find RTP stresses Xie, this procedure is mainly a function of G726. Packaging whole G726 for g726_Encode and g726_Decode two functions, Parameters for the compression and decompression of data storage address pointer, 960 bytes can be compressed to 120 to 120 bytes and bytes to
