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

eXosip is a GPL library that extend the capability of the oSIP library. It aims to implement a simple high layer API to control the SIP for sessions establishements and common extensions.

使用eXosip开发的例子，使用vc打开工程直接编译库和例子，注意需要安装了xp平台开发包-use eXosip development example, the use of open vc works directly translated libraries and examples, the need to install the Platform Development Kit xp

SIP协议，中文，也是网上掏来的，大家参考，谢谢。-SIP agreement, Chinese, is also out to the Internet, the U.S. reference, thank you.
