what you saw was an analogue modem connected to a normal telephone
line, not a GSM modem. I have a [gsm] external, but GSM modems
usually don’t support detection of DTMF tones, so in order to trigger
anything you’d have to pass the audio on to the mac and do the DTMF
detection separately. If you really find a GSM modem that does it,
please let me know!
