Incoming Faxes Now Failing

Please review -> http://www.freepbx.org/forum/freepbx-distro/distro-discussion-help/fax-destinations-sip-detection

For about a week, I managed to get our PBX to answer and receive faxes flawlessly. However over the weekend, I had to move some equipment and after bringing the PBX back up, it is unable to receive faxes at all.

I will try and provide as many logs as possible… Please let me know what else I need to provide in order to fix the issue.

Log file info after break…

Any help or direction would be greatly appreciated… My alternative is to freshly wipe the PBX, but it’s a production system, so I’d much rather work through the problem than the latter.
