用vb编的一个拨号电话软件程序，希望对visual basic编程感兴趣和希望了解拨号电话软件程序原理的人有所帮助...

本程序自带反向回传语音代理服务，可以使两个不同局域网内的客户机通过国际互连网进行语音通讯，本程序使用点对点方式，不通过任何中介服务器速度快，语音延迟极小，声音清晰逼真，其效果和真实IP电话不相上下，程序界面简洁，操作简单，是在互连网上打IP电话的极好工具，唯一的要求是通话双方都要有电脑，并连入互连网。 本程序能实现以下连网操作功能： 1.通话双方是同一局域网内的用户 2.通话双方是不同局域网内的用户，并通过各自的网关连入互连网 3.通话双方一个直接连入互连网，另一个处在局域网中，并通过网关连入互连网 4.通话双方直接连入互连网 一般的语音聊天软件只能实现1，4两种连网功能，而本程序能完全支持所有这四种连网情况，因而能使所有用户享受到语音聊天所带来的好处.-reverse the procedure own voice back-agency service, can make two different LAN client through the Internet for voice communications, point-to-point use of this procedure, not through any intermediary server speed, voice minimal delay, loud realistic, and the real effect of IP phone lines, procedural interface simple, simple operation, the interconnection of the IP phone online playing an excellent instrument, the only requirement is to call both sides have to have a computer, and connect to the Internet. This program can achieve the following networking feature : 1. Both the caller is within the same LAN users. Both the caller is different us
