IP电话编程

基于sip协议的视频会议源码 ，里面包含AudioConference，dsp，include，TestVideoConference，TestVoiceConference， VCodec_Xvid，VideoConference几个目录，对应学习sip和视频会议的用户有很 好的帮助。

一个很好的SIP协议栈,用标准C实现.大家学习吧.-A very good SIP protocol stack, using standard C realize. Everyone to learn it.

软交换测试工具,可以反编译查看代码,良好的架构-Softswitch testing tools that can decompile the code view, a good framework for

一个用VC写的电话会议的系统.能够在少于四人的情况下实现高质量的语音效果,用语言实现了语音的混频-It is a video conference software writted by VC++. It show the perfect performance even when 4 people talk at the same time. voice mixing technolog be used.

RTC下接收呼叫的例子（如果是VC用户，请新建一个APPLICATION 32空工程，然后，用ADD FILE的方法把所有的文件包含在工程中编译）-RTC receive calls example (If yes VC users, a new air APPLICATION 32 works, and then use the ADD FILE all the documents included in the project compiler)

SIP RFC协议标准,只可惜是 英文版的，可做参考-SIP RFC protocol standards, but unfortunately are in English, can refer to

排序软件，按姓氏笔画等进行排序的一个软件，用vb.net进行编写的-Sort software by name, such as stroke sort of a software using vb.net for the preparation of the

Windows Mobile Professional 6 及更高版本上利用SMS自动进行状态回复的程序。还包括了以下演示： 使用SMS拦截； 使用配置文件； 检查Outlook约会信息； 基于定制策略对不同电话号码作出不同反应； 使用SIP； 在Windows移动设备上使用db4； 使用提示； 多语言界面和本地化。-Trombone a utility for automating status reply via SMS on Windows Mobile Professional 6 or later. It also demostrates: How to use SMS interception How to use configuration file How to check Outlook appointment information How to react with different phone number based on custom policy How to deal with SIP How to use db4o on Windows Mobile device How to use notification How to enable multilingual user interface and do localization

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

我自己开发的一个点对点的视频传输会议程序，希望大家指导呀！-I developed a point-to-point video transmission of the proceedings, we hope to guide!
