[comp.sys.mac.hardware] how do I read touch tone signals?

jcocon@hubcap.clemson.edu (james c oconnor) (06/25/91)

Idea - hook up a phone to my Mac (some conversion box which takes in
RJ11 and outputs to serial/NuBus/ADB/...) and then passes on touch tone
signals to the Mac.  The Mac can then play back digitized sounds to the
phone line in response.  I guess that kind of rules out adb :)

Does this box exist?  Where can I buy it?  How many lines does it
handle?

Thanks in advance, and following the responses individually to all
who e-mail me.
