[hylafax-users] Recieve Errors

[Stephen Carville <stephen@xxxxxxxxxxxxxx>]

OK, I replaced the USR modesm with a Multitech ISI5634-PCI/8 card.  This seems 
to have cured all the previous problems but, as luck would have it, a new 
problem has come up.  At least one customer is claiming their fax machine 
cannot maintain a connection.  The only errors I found for today were nine 
instances of "RECV FAX: RSPREC error/got DCN"  Here is a sample transaction:

Looks like the fax modems cannot agree on how to send the data.  Is this 
something I can fix from my end?
