Most modems will not be capable of this.  I think I have een ads
before for modems that also do "voice mail" (tone recognition, speech
synthesis, sampling) but that was on a PC and was a specialized
product.  Your average modem has no circuitry for tone recognition.

You could conceivably build the hardware for it; a tone recognition
circuit isn't hard to build.  You can even get a chip from Radio Shack
which will do most of the work for you.  Of course, then you have the
problem of interfacing with the computer, both hardware and software,
and you need to detect the phone ring to answer.  All in all, not a
simple hardware project perhaps, but not unrealistic.

If there is already such hardware available commercially, I wouldn't
be surprised, but I can't say where to look, as I don't know.  Perhaps
someone else can fill in the blank.
