[hylafax-users] COMREC invalid response received PSTN <--> Asterisk <--> Hylafax

[Joseph <syscon@xxxxxxxxxxxxx>]

Can somebody point me in a right direction.
I'm running Hylafax with Asterisk:
PSTN <--> Asterisk <--> Hylafax

I'm using an external "MultiTech Modem"
Sending faxes works flawlessly, though receiving faxes works 90% of the
time.
I'm using Asterisk NVBackgroundDetect function to detect incoming faxes.
For most of the fax transmission I receive works fine. But it
happens many time that I receive the page transmission OK but the page
is not confirmed back to the sending party.  I get an error:
COMREC invalid response received

so their fax machine is retransmitting the page even though I received
it OK.  Here is complete fax report from Hylafax:

The full document was not received because:
