I'm not sure I can help, but I wanted to make a related point.

This posting is a nominee in the category  "Best Bug Report to a
Specialized Software Mailing List".  

It contains all the important stuff:

Class of modem (although not make and model):

Is the install new, and how did it go:

What is the problem, in some detail:

And, what diagnostic steps have you already taken:

Did you already try other resources, and which ones?

Hmmm... Does it happen from _any_ fax machine, or just the one you were
using as a test?

He even includes the equipment rundown, including OS release:

And even tells us that he's using the RPM(!):

My first suggestion, Tony, is: if you haven't tried more than one
sending fax machine, you should.  It would also be useful to know if
the system _sends_ faxes correctly, even if you don't plan to do that
in production.  And, finally, have you tried turning the port speed
down, and trying various handshaking methods?

Let us know.
