我这段代码是一个名为Youtoo的sipphone工程改编而来。（www.pudn.com 上有） 原工程是在vc 6.0下开发，而我是在vs 2005 把代码重新改写了一边，同时稍微改了一下界面。 我用来测试客户端（ua）的服务器是 Brekeke SIP Server(安装完后可以注册)。 在程序运行前应该在vs2005重新设置lib和头文件的位置。 库放在lib目录下 头文件放在include目录下。(I have this code is a Youtoo adapted from the sipphone works. (Www.pudn.com have) the original project is developed in vc 6.0, while I was in vs 2005 to rewrite the code aside, at the same time slightly changed about the interface.
