Asterisk would handle the voice portions, the data part would need to be
handled first by the HDLC driver and then it will appear as an interface
similar to a ethernet port. Then you would use IPTables or whatever your
version of the kernel is supporting to act as a firewall as routing
itself will be mostly natural once you let the kernel know to forward
packets from one interface to another.

While it is possible that there may not be any need to reprovision with
the ISP, it is possible it would need to be too. Check to see if the
data portion is being sent as HDLC. If so you should be able to discuss
with them just replacing the Adtran box with your asterisk box.

Then you just need to make provisions for your fax machines to get
access to a phone line either via a SIP to FXS device or maybe one of
the TDM400 cards.
