Try Cermetek at +1-408-752-5000.  I've used a device called the CH1812
which provides part 68 certification.  It also includes the hybrid,
incoming ring detect, and offhook circuitry -- these features are a
side-effect of the certification requirements.  The module actually
comes with a sticker you attach to the outside of your finished
product.

The CH1812 is a PCB approximately 2" square.  They may have something
newer now, it's been at least 5 years.  I've seen a cermetek modem
which was smaller than the CH1812 and included all the 1812 features
PLUS a 2400bps hayes AT compatible modem.
