Pennsacola FL will report ringing, sieze a line, dial, listen to touchtones, and play and record segments of sound on a phone line. You can also queue up the sound segments, and upload/download them. I think the selling price is around 00. It has a rom with some prerecorded letters and numbers (sounds) in it. It doesn't do any waveform compression like the PC Answering machine boards with the DSP's or CPU's do. Warning: even at 38,400 Baud, you can't keep up with sampling at its highest data rate (8K 4 bit (delta?) samples/sec), and the protocol seems to have no error checking. It can barely keep up at 6K with binary transfers. Unix tty drivers usually have trouble with high baud rates... I currently can't figure out how to keep the thing offhook after a successful dial, but I haven't been spending much time with it. What I really want is a box like this that works with a bidirectional parallel port, or a SCSI interface; or ethernet/tcpip/telnet so it can transfer data fast enough. Anyone got any ideas?
