Jeremy there are DTMF chips to do this function BUT from what I gather you
are having a play, so lets see.....how about using your sound card with
Electret mic stuck onto the handpiece?? Use Delphi to decode the frequencies
and write your own lookup tables; should be a piece of cake for a man of
your calibre. Dont forget to add parity of some form or another to prevent
the anti-gravity machine operating whilst you are talking to the boss.
Actually I was thinking about applying this in our future house to be built.
It would make good sense to include audio and power control wiring while
building so we can make use of my then redundant Notebook PC to voice
control lighting etc in all the rooms. Man wouldnt have to get out of bed
eh?
Cheers,
