It is inevitable that any time something bad happens, those in power need to
pass down
an edict saying to "Never Let It Happen Again". Whether or not this is
possible is
irrelevant. My Sympathies :(

Number one doesn't sound so good. If you could get some form of hardware for
PBX that would sense the incoming fax call, and be able to pass the call,
along with the
DID information in question, to HylaFAX, then you'd be good to go. This
piece of your PBX could be hard to come by however.

Considerably more likely. What you would need would be your 80 DIDs, ISDN
line incoming, the cooperation of your local telco to provide the DID
reporting, an
ISDN card which works with HylaFAX, a little time and patience, and voila.
This will
not be a cheap solution, but it is doable. I believe that the Eicon DIVA
cards have
been reported to work well in this application. I have not done this, but
looked into
it for our own setup. When I gave my boss the price tag, it was quickly shot
If there is a hard core push for this, there is now a commercial provider of
support that you can consult with, email sales@hylafax.org if you want to go
that way.
Otherwise, check the mailing list archives for DID and/or DNIS, it should
turn up
some hits for you.
BTW, if anyone who has done this is feeling generous, this would probably
make a
great topic for a how-to. The question comes up often enough.
