He's not going to use "an answering machine"....
He'll have some smarter-than-that system do the response.
Note there are complete systems for this available, not just DTMF
decoders. They are used for remote control of items via dialup.
One example -- rebooting hung servers. Another -- remote control
of isolated transmitter sites, but broadcast and two-way radio
repeaters. The amateur radio field has used such for years. (The
FCC used to require amateur repeaters have out-of-band supervisory
control; phone was cheaper than a 2nd receiver package.)
