IP电视电话会议的实现 -Implemention of IP videotelephone meeting

可以用vc编译的一个sip 客户端,使用一个基于osip,exosip,ortp和mediastreamer的高层库.有该库的使用文档-Vc compiler can use a sip client, based on the use of a osip, exosip, ortp and high-level Treasury mediastreamer. The use of the library documents

voip实现的原代码 rtp协议辅助工具类代码-voip realize the original code rtp protocol aids category code

Delphi写的IP电话源码-IP phone sourcecode writed by Delphi

sipp源代码，sip协议测试桩，附场景文件-SIPP source code, sip protocol test piles, attached to the scene file

个人编写的源代码＋执行文件，可以运行！实现局域网内语音通讯！开放代码-Personal preparation of the source code executable file, you can run! LAN realize voice communications! Open code

网络电话。采用GSM语音格式，2.2KB/s的数据流量，支持HTTP, Socks4/5单一代理或二者同时代理。本版本修复了以前版本的一些小问题，增加了动态调整延时，打开、关闭话筒和声音，保存和自动加载通话地址列表，代理服务器列表，使用全部或部分本机地址开机-telephone network. GSM voice format, 2.2KB/s data traffic, supports HTTP, Socks4/5 of a single agent or combination of both agents. This version fixes previous versions of some small problem, the dynamic adjustment of delay, opening, closing and microphone voice, preservation and automatically load calls address list, the proxy list, the use of all or part of the machine addresses boot

RTC下接收呼叫的例子（如果是VC用户，请新建一个APPLICATION 32空工程，然后，用ADD FILE的方法把所有的文件包含在工程中编译）-RTC receive calls example (If yes VC users, a new air APPLICATION 32 works, and then use the ADD FILE all the documents included in the project compiler)
