I'm in the process of doing just that, using a US Robotics Sportster 
Voice modem, with the caller ID provided separately from a BT Airway
box.

My primary motivation was to answer the phone and play a suitably terse
message if the caller has withheld their number - we get a lot of 
problems hereabouts with Anglia Windows.

To get you started look for the "Rockwell Voice Commands"
document on 
the web. If you can read C, then mgetty has a module called vgetty with
some useful reference code, and the perl package LVRS does a similar 
thing (these both have a linux flavour, I'm afraid).

The main pain in the arse is that voice modems use GSM or ADPCM formats
for their audio data, but again if you can read C I can furnish you with
my code for converting between GSM and WAV format. Then you can just 
plonk the wav files on a web page and check your answering machine 
messages from a browser in work ;)
