Not that I'm aware of.

Sure.  N4TXI built the WhereAVR (
http://garydion.com/projects/whereavr/ ).  It's built on the ATmega8,
same processor as the original Arduino.  You'd need to do a fair
amount of work to adapt timing, etc, to the arduino's 16MHz clock.

You can also interface it to a modem IC (e.g. MX614) and let it handle
the analog work.

I'm playing with a CMX865A modem IC which can do 1200 baud tones,
DTMF, and several other modes (TX and RX). It's 3.3V in a surface
mount package.  I'm working on a 3.3V to 5V interface on the digital
side right now, to make it compatible with 5V arduinos.
