Sorry, I don't have an answer for you.  FYI, I've been having the exact 
same problem with a certain fax machine (in my case a software based 
one).  I've tried the latest from opencall.org v1-0_STABLE and the 
latest CVS-HEAD.

Faxing is definitely tricky work - and I imagine there are hundreds of 
variables that could cause it to fail.
On a positive note - it does appear to work with _some_ fax machines.

Can anyone out there offer some tips regarding getting rxfax to work 
better (aside from links off of wiki)?  Like maybe playing a background 
sound before executing rxfax or something crazy like that?
