gsm to max on osx


    Dec 12 2006 | 8:24 pm
    hi list,
    i'd like to investigate the possibilities that exist to let regular
    phones call a gsm that is connected to a mac (would a gsm usb modem
    be the thing in need?).
    the things that i would like to use are
    a) dialing tones passed on to max, for triggering
    b) spoken sound passed on to msp, for sound processing
    [ok, a) could be realized thru b).. would that be the way to go?]
    i saw a) possible in an installation by olaf matthes; b) should be
    possible, too.
    but are a) and b) possible in the same constellation?
    any tips on modems, connections, additional soft/hardware that would
    make this possible are welcome!
    thanks,
    jan klug

      Hi Jan,
      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!
