I need general information on voice modems. Any source, links to resources,
tech info would be appreciated. I don't want toolkits or ActiveX controls. I need:
1. the AT command set for play, record, dtmf detection ,etc.
2. An idea of what standards there are for the voice modem commands, ie, is the AT commands
(or a subset) a standard across all voice modems or does each manufacturer have their own.
3. How TAPI works with voice modems.
4. Sample C source for AT command or TAPI/voice modems
Any help would be greatly appreciated.
Thanks in advance,
