使用TAPI3.x库，参考了网上能找到的源代码，具有如下功能：拨号，应答（录音，播放）



由于我使用的TSP线路不支持媒体流，也不支持MSP，为了实现answer machine的功能，也就是播放及录音，参考了temp77的API层实现语音播放录制。



由于指定了打开的线路，所以具体使用的时候还需要根据本地连接的硬件设备另外选择线路打开。-TAPI3.x library use, reference to the Internet to find the source code, have the following functions: dial-up, response (recording, playback) because I use the TSP does not support the media stream lines, nor to support the MSP, in order to achieve the answer machine function, that is, broadcast and recording, with reference to the API layer temp77 the taped voice. Designated because of the lines open, so when it comes to the specific use required in accordance with the local hardware devices connected to the other selection lines open.
