I've done something similar in the past by using external Adtran DSUs

the channels out which are used for voice, FAX, etc. and get/pass them
from/to the PBX using a DSX-1 interface before they ever hit the V.35
interface which plugs into the back of the router.  

In this configuration, the router neither knows nor cares about the
channels which aren't used for data traffic.

Even using the DSX-1, wouldn't she need 2-wire ringdown cards to supply
POTS lines to the fax?  Seems like it would be less expensive than putting
in a PBX to handle fax traffic.
