g7 series of audio codec code, can help you in the use of voip

具有异形窗口的网络电话,可以实现网络通讯,并且可以学习如何创建异形窗口.-With special-shaped windows network telephone, network communication can be achieved, and can learn how to create a shaped window.

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

H323协议的Windows实现，开源代码，可直接使用。-Windows realize H323 protocol, open source code, can be used directly.

关于VOIP系统的详细介绍，有助于VOIP系统的设计-on VOIP detailed description of the system, contribute to the design of VOIP System

利用JMF开发的语音聊天客户端，采用UDP传输-JMF developed using voice chat client, using UDP transmission

这个项目是一个简单的sip-Voip软电话客户端你只要配置你的sip服务器名称和传递字和代理，然后你必须知道你的客户端的所有IP地址，并有乐趣与你的朋友打电话，你也有开放的源代码，使你想做什么样的改变。祝你好运

为北京移动项目制作的SIPP呼叫脚本，主要用于用户的注册、发起呼叫等脚本，实际应用于北京移动的并发呼叫测试项目中，非常具有参考意义。

主要通过对SIP协议的研究，根据这个协议的特点，设计出来一个基于SIP电话会议系统。用户可以通过WEB方式登录到预先建立好的会议室，进行电话会议。-primarily through the SIP, according to the characteristics of this agreement, designed a SIP-based telephone conferencing system. Web users can log on to advance ways to establish good meeting rooms, conference calling.

基于sip的服务器程序，java编写，很不错的-Procedures based on the sip server, java prepared, very good

本源码主要是h.323的协议栈，对进行voip开发人员会有很好的帮助，本开还有rtp和sip协议栈的源码，有需要可以联系-The source is mainly H.323 protocol stack, the conduct of voip developers have a very good help, there is the open rtp and sip protocol stack source code, there is a need can contact
