I've done something similar in the past by using external Adtran DSUs
with pass-through capability. I set the channel-map in the DSU to pull
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.
