That'd depend somewhat on the behaviour of the modems used to dial in.
If they use a calling tone (just like faxes do), then you could use a 
fax switch. They pick up, see if they hear the calling done (1100 Hz 
beep for 1/2 second, every 3 seconds). If so, they presume it's a fax 
(or in your case a dialin modem) and if not, they make an attached phone 
ring or an answering machine or whatever.

All modems do it in fax mode, however, not all do it for modem calls.
Can be tweaked with AT commands of course.


One other way could be to build an Astisk PBX with voice response menus, 
have it tell the caller to press a certain digit to go to the voicemail, 
and otherwise the system should timeout and connect to the dialin modem.
Probably more fussy ;-)

Regards,
Arjen.
