NO JOY Suddenly faxing is not working

[mikemcc11]

I have PIAF system with Asterisk 11.10.2 and FreePBX 2.11.0.38 and Incredible 11.10.

Faxing has been working fine with IncredibleFax 11 for months. A few days ago I noticed that we had not received any faxes. I was then told that outgoing faxing wasn't working either. I opened the CLI and watched what happened when a fax came in. Here is the output:

I checked the logs in iaxmodem. I found iaxmodem shows all 4 modems starting. The modems logs show registration timing out.
Any help would be greatly appreciated.

OK. Now I know why I couldn't find any solutions on the forum or Google. As they say you can't fix stupid. Apparently I had accidently deleted a ';' from the 1st comment line of iax.conf. That caused iax registration to fail - so no modems- so no faxes. I looked in all the logs and found lots of symptoms. I knew what wasn't working but I couldn't find a clue to what the cause was until I found a thread that was helping someone diagnose a totally unrelated issue. The instructions said to open the CLI and issue 'iax2 reload' as the responses came back I saw an error about line 1 of iax.conf having a problem with a comment. Opened the file, fixed the missing ';', restart asterisk.......and eureka - the fax she is a working.
