The message basically means that as we're negotiating our fax to be sent 
to the receiver that the receiver does not seem to be accepting (or 
hearing) our selection of the receiver's capabilities to be used.  If it 
is reproducible then it generally means that you have bad phone lines 
(the receiver can't hear you) or there is some bug in HylaFAX Class 1 
driver.

If it is reproducible.  If it fails like that every time to certain 
receivers then it probably means a bug.  If it fails like that 
sometimes, but not always, to many different receivers, then it probably 
indicates poor phone lines.

If it's a bug there may be some workaround, but probably not.

Follow what your modem manual says, although I doubt that either of them 
would cause you a problem.
