Yes, I do know very well ;-(
We're a long time ISDN users (we've had digital phone lines since ~12
years ago) and know very well the problems they can have, mainly when it
comes to the hardware facilities and faxing.
The fact is that we still maintain a bunch of digital subscriber lines in
the office to which I have connected the analog modems (we do "fax" a lot
here) but I have experienced isolated problems when dialing to another
ISDN lines over an analog line/device, that is, the call (even a
telephone call) cannot be placed and our carrier, of course, does not
know a thing about where the problem can be :-)
The above means that -in such specific cases- faxing from analog modems
fails (eventhough the modems are connected to an ISDN line!) and I think
that faxing over an ISDN device could work.
So as I always like to have several options from where to choose, I
thought in adding the possibility of using this card to provide digital
faxing so I can handle almost any unexpected situation. And in the event
the ISDN card works fine with HylaFAX and has no problem at all, I can
make it the default device to manage the standard input/output fax queue
and keep the external RS-323 modems as a fallback device.

Hmmm, thanks. It was a very recent post (from this same year!) so yes, it
seems that faxing (capi) using the new driver (misdn) is still in a beta
stage. I'll have to consider that.

Okay, I will for sure take a look at the mailing list archives to see
what's the status of the project and have a better understanding of the
current supported features.

Thanks for the input :-)
