语音聊天系统采用VB开发包括客户端和服务器

voip实现的原代码的一个部分 sip协议的实现-voip realize the original code a part of the agreement realize sip

主要通过对SIP协议的研究，根据这个协议的特点，设计出来一个基于SIP电话会议系统。用户可以通过WEB方式登录到预先建立好的会议室，进行电话会议。-primarily through the SIP, according to the characteristics of this agreement, designed a SIP-based telephone conferencing system. Web users can log on to advance ways to establish good meeting rooms, conference calling.

SIP协议中穿越对称型/非对称型NAT防火墙的多种实现方法，解决私网内部的防火墙穿透问题。-SIP cross symmetric/asymmetric NAT firewall multiple solutions, private internal network firewall penetration.

程序源码 很通用的-procedure is a common source! !

SIP_ISUP，SIP ISUP互联互通协议部分，对于学习NGN软交换之间的协议流程很有帮助。-SIP_ISUP, SIP ISUP protocol interoperability of NGN Softswitch to study the agreement between the flow of great help.

RADVISION RTP源代码-RADVISION RTP source code

基于语音传输的电话会议系统源代码，非常值得借鉴和学习-Based on voice over the telephone conferencing system source code, very much worth learning and learning

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

搞VOIP的一些原代码，包括MGCP,SIP,RTP/TRCP,SRTP(加密RTP)...等源码，参考价值无限！！这可是我所有的收藏阿，我都献给大家了:=)-engage in a number of VoIP original code, including MGCP, SIP, RTP/TRCP, SRTP (encrypted RTP) ... other source reference value unlimited! ! But it all my collections A, I have dedicated to you : =)

osip，exosip，ortp...是在网络电话中使用非常广泛的几个开源库。这里是在VC7环境下已经编译好的lib文件和dll文件，在windows环境下可以直接使用，省却了重新编译的烦恼。-osip, exosip, ortp ... is the phone in the network is widely used in several open source libraries. Here is the VC7 environment has been compiled lib files and dll files in the windows environment, can be used directly without the need to re-compile troubles.
