We run Asterisk 13 using the FreePBX 184.108.40.206 distro based on CentOS-6.4. We also run HylFAX+ 5.5.3 with iaxModem 1.2.0 on the same system with AdvantFAX as the web front-end. Our two fax lines are configured as iax2 DEVICES.
These components have been working together through various versions since 2013. On Tuesday last our site was subjected to a prolonged power outage that drained our twin UPS set up flat resulting in a power down state for the Asterisk host.
Upon power recovery the asterisk host system came up, the phone system works, but we are now unable to receive faxes through Asterisk. We can send faxes but not receive them. The fax line never picks up and a redirect to a voice recording informing voice callers of their mistake is triggered instead.
I have a trace of the asterisk ‘full’ log that captures one of these failed calls and I would like some help in determining if a clue to what has happened is contained therein. I do not wish to simply post it to the list with getting permission since it is quiet long. But I
do need to get this resolved and I cannot fathom why the lines are not picking up incoming faxes.
Any help would be gratefully accepted.
