you're perfectly right ;-)
We have lots of Livingston Portmaster 3 and Cisco AS5200
that all have E1/PRI interfaces. If such a box could
do fax services too, and if Hylafax would provide an
interface to these, we wouldn't need any new hardware.
Cisco is already working on a Fax solution for their
AS5300 system, see


(oh, what an URL... -- maybe better search for "fax modem"
on Cisco's homepage ;-) )

This solutions appears quite interesting since it directly 
interacts with an SMTP mailer. However, it needs voice/fax 
modules installed and is available in IOS 12.0 only. 
Moreover, an AS5300 costs about $30,000 plus the voice/fax
modules. Slightly to expensive, and it wouldn't help
Hylafax at all.

There's also a so-called "T1" box which has an E1 interface
but has a non-standard interface to the host computer. This
box might also be interesting.

I'm quite sure that this is possible. However, I don't have
time to do it myself and doesn't know someone who has the time
*and* is able to do it ;-)

I don't know how much that would cost. Any idea? Perhaps someone
else is also interested? I think of the TPC people that must
have similar problems all around the world...
