Sure there is a way.  A couple of ways (at least).

1) Get a 4-port TDM card and install it into your Asterisk box.  
Connect the TDM ports to your modem ports.  Then forward incoming calls 
on fax DIDs to those TDM ports.

2) Get another T1 port in the Asterisk box and get a T1 fax modem and 
do the same thing.  You probably don't have the fax-demand to justify 
the hardware expense, though.
