I've had very good results at one of my clients' locations using the
following setup:

PRI <--> Asterisk w/Digium TE406P <--> Adtran channel bank <--> Fax machine

Assuming you have a spare span on your E1 card, it's probably worth it
to get a channel bank with 24 FXS ports and put it in your wiring
closet.  Even if you don't use all the ports now, you'll be a simple
cross-connect away from adding an analog station if and when it's
needed in the future.
