asterisk users - Mar 2014 - Oddity with FFA

Hi all,

For the most part, we are finding that Fax for Asterisk works pretty
well.  However, we have seen some wierdness that we'd like to try to
fix.

Once in a while, we will get a partial result report for a given fax
but when we look at the actual .tiff image, it looks to be complete.
This is causing our users to not get a positive acknowledgement when
they send the fax.

Is there anything we can do to mitigate this?

Mike.

How do you know the FAX is complete? If a page was received, the sending 
machine said more pages were to follow, and then it dropped the call, is 
that a complete FAX?

One of my customers had this problem. The cause turned out to be the other side
(one particular
remote station).

In addition to res_fax, I also installed the Hylafax/iaxmodem combo. Hylafax has
the advantage
of giving nice logs about the signaling. This way it was easy to see what was
going on, but I
have forgotten the details meanwhile.

We also faced from time to time a reception problem and improve it like 
this: after faxreceive, if faxopt(status) is different to SUCCESS we 
check if faxpages is greater than zero, if yes, if faxopt(error) = 
NO_ERROR. In this case we consider that fax is well received. Asterisk 1.8
