这是与一本书－《SIP协议及其应用》配套的电子教案。

在ip电话或者视频通讯开发中，常常需要穿越nat，stun是个不错的选择-In the ip phone, or video communication development, often through the nat, stun is a good choice

视频会议传输协议，同行人一看就知道视频会议传输协议，同行人一看就知道-Video conferencing transmission protocol, peer-person, one can tell

使用JRTPLIB库实现RTP的传输RTP是目前解决流媒体实时传输问题的最好办法，如果需要在Linux平台上进行实时流媒体编程，可以考虑使用一些开放源代码的RTP库，如LIBRTP、JRTPLIB等。JRTPLIB是一个面向对象的RTP库，它完全遵循RFC 1889设计，在很多场合下是一个非常不错的选择，下面就以JRTPLIB为例，讲述如何在Linux平台上运用RTP协议进行实时流媒体编程。-JRTPLIB use of RTP for achieving the transmission RTP is to solve real-time streaming media transmission problems the best way, if necessary on the Linux platform for real-time streaming media programming, can consider using open-source library of RTP, as LIBRTP, JRTPLIB so. JRTPLIB is an object-oriented library RTP, which fully comply with the RFC 1889 design, in many occasions is a very good choice, following on to JRTPLIB example, on how the Linux platform on the use of RTP for real-time streaming media programming.

这是一个用vc开发的基于CMPP的短信收发程序-This is a development with vc CMPP based on the short message TX procedures

是Opengatekeeper项目的扩展。它支持通过RTP（音频和视频）网守的路由和T.120通讯，因此没有通讯直接在endpoints间进行。-Opengatekeeper project is the expansion. Through its support for RTP (audio and video) Gatekeeper routing and T.120 communications, there is no direct communication between the endpoints.

不错的资料 需要的可以参考！-good information can refer to the need!

c++的voip应用源码，很简单的一个例子-c++ the voip application source code, a very simple example

基于DirectShow开发的一个视频和Windows桌面远程监控程序，比较简单易懂，提供了完全的C++源代码，可执行可复用，希望对大家工作上有帮助。-based on the development of a DirectShow Video and Windows desktop remote monitoring procedures, relatively simple to understand and provides a complete C source code, the executable can reuse, and I hope to work with you to help.
