Re: [hylafax-users] Destination user reports receiving incomplete faxes



Thanks Darren.  I’ll see if I can nudge the systems admin to upgrade our Hylafax server to 4.4.4.  I know last time I mentioned it he grumbled about having to do a special build or some such.

 

How would I configure Hylafax to disable Error Correction for a specific destination fax only?  This isn’t something I’m familiar with, and initial web searches didn’t reveal the answer.

 

Thanks again!

Stott,

 

Your logs do indicate that  ECM is coming into play here to retransmit frame number 13, so you do have a little signal degradation going on, but this is not uncommon and should in itself be causing a problem. It's possible with such an old version of HylaFAX that you're hitting a bug that's fixed in the current 4.4.4 release, so I recommend upgrading if that's an option for you. If the problem persists in 4.4.4 there's a lot more elaborate test procedure you could do to help pin this down.

 

If the problem is on their side, you might be able to work around it by disabling ECM when sending to this destination.

Hello folks,

 

I’m hoping someone can point me in the right direction in my search for a solution.  I have a particular fax destination that indicates the faxes they are receiving (which were sent from our Hylafax server) are incomplete or cut off mid page.  I’m not receiving errors indicating there was a failure, but the logs indicate we’ve been getting partial page signals.  Is this indicative of a noisy line, a bad modem configuration or a problematic destination fax machine?  Any good methods for narrowing this down and resolving?

 

Thanks in advance!
