Though I do not have your "fax-experience", I had the same impression 
(because that's the trace I get for a voice call). But as I wrote, the 
same machine some times works. I think it must be an old fax machine : 
is it possible that this fax "waits" for sthg without sending any fax 
tone?? Before, when there was just a hardware fax machine on our side, 
the guy had no problem to send faxes.

Yes, the fax was nearly OK (just the 3 last lines with some garbage in 
the pixels). But the remote machine "told" the sender that ther was an 
error and he sent the fax again, this time without any error.
