[comp.sys.ibm.pc] decoding touch-tones?

Has anyone decoded touch-tones off a phone line?
Modems can generate them, but I haven't seen any that
can read them.

I know there are things like the Complete Ansering Machine
around for $300, but has anyone hacked up (or bought)
something better (cheaper, mostly).
All it needs to do is tell me which key they hit.

Any pointers MUCH appreciated,

For what it's worth, Radio Shack has a touch-tone decoder chip that can 
decode the tones.
