一款最为经典的SIP-one of the most classic SIP

通过此程序可以对所有呼入和呼出的电话进行录音实现实时监控的功能-Through this procedure for all incoming and outgoing telephone recording realize real-time monitoring function

版本V4.1.1,Linux上的开放源代码的IP电话软件SIP协议，主要用于语音通话，但它也支持发送文本的即时消息，即可以像ICQ那样地用文字聊天。 如果网络带宽足够的话，它还支持可视电话 Kphone是GPL的开放源代码的软件。-version 4.1.1, It is IP phone software of Linux open source code based on SIP protocol, it can be used to voice communication, and surpport text IM, same function as ICQ used to text chat. In broad band circumstance, it surpport video conference. Kphone is GPL open source software .

C++6.0实现语音采集与播放的控件。souce code 中为该程序的源代码 由于编写该控件的过程中用到了Directx8.1 所以需要安装 Directx8.1sdk 在路径中加入所需的lib exe 中的 ocx 用之前需要用regsvr32 进行注册 如果机器安装的Directx版本低与8.1的话不能运行 该控件没有对语音包压缩 所以对网络环境要求比较高 该控件在校园内经过性能测试-C 6.0 Acquisition and voice broadcast controls. China souce code for the program"s source code because of the preparation of the controls used in the process of Directx8.1 Directx8.1sdk therefore need to install the path to join the lib exe randomly with the use regsvr32 required before registration if machines installed DirectX version 8.1 with low so can not run the Controls no compression of voice packets so the network environment to the high demand on the campus of control after performance testing
