There is a project in Circuit Cellar Ink (June/July 1991 - Issue 21) that 
describes what you are asking for.  The schematic is too complex for me
to reproduce with ascii characters, though.  You can get a back issue from:

Circuit Cellar Incorporated
4 Park Street, Suite 20
Vernon CT  06066
(203) 875-2751
BBS (203) 871-1988

This project uses an 8052 uP, SSI204 DTMF decoder, XECOM XE0002 DAA, and
the RC Systems V8600 voice synthesizer.  It's a nice project designed
as a telephone interface for home automation/monitoring.  Sorry to
sound so much like an advertisement.  I'm using the project as a basis for my
own but I'm using a different uP.  Also, <disclaimer follows> I'm not
associated with Circuit Cellar other than being a satisfied subscriber.
