使用组播技术的音频会议 - The use group broadcasts technical the audio frequency conference

通过此程序可以控制电话的输入呼出实现简单的pbx功能-This process can be controlled through the phone input exhaled realize pbx simple function

视频会议系统,在VC环境下编译通过,大家可下载下来-Video conferencing systems, in VC environment compiled through, everyone can be downloaded

网络NC v1.0 源代码.rar-network NC v1.0 source code. Rar

使用Rtc/RTCP技术来传输VIDEO和SOUND的程序(需要到MICROSOFT下载最新的RTC CLIENT SDK API才能编译，VC7不需要下载)-use Rtc/RTCP technology to transmit VIDEO SOUND and procedures (need to download the latest Microsoft RTC Client API SDK can be built, VC7 do not need to download)

该程序可以用于两个人在LAN/Intranet(或者Internet)上进行视频会议。现在有许多视频会议程序，每个都有各自的性能提升技术。主要的问题是视频会议视频帧的尺寸对于传输来说太大。因此，性能依赖于对帧的编解码。 -the two procedures can be used in LAN/Intranet (or the Internet) for video conferencing. Now there are many video conference proceedings, each have their own performance enhancements. The main problem is video conferencing video frame size too large for transmission. Therefore, the performance depends on the right frame codec.

一个H.323协议栈，C源程序，跨平台，实现了H.225，H.245，RAS，和RTP。-an H.323 protocol stack, C source, cross-platform, achieving H.225, H.245, RAS, and RTP.

KPhone is a SIP (Session Initiation Protocol) user agent for Linux, with which you can initiate VoIP (Voice over IP) connections over the Internet. KPhone requires KDE (K Desktop Environment) or at least various libraries from the KDE package. KPhone also requires the OpenSSL libraries to be present in the system. KPhone has been somewhat tested on Red Hat 7.2 and 7.3, Slackware 8.0, SuSE 8.1 and Debian. Requirements on each distribution vary according to the installation layout.

QtPhone is a cross-platform telephone emulation application designed to be used with a PC, speakers, microphone, V.92 voice modem and a standard phone line. ISDN, xDSL and VoIP will be supported. Features include Caller Identification and Voice Mail. -QtPhone is a cross-platform telephone emu IBM application designed to be used with a PC , speakers, microphone, V.92 voice modem and a standard phone line.
