[Asterisk-Users] Red Alarm

[Marconi Rivello]

I posted a while ago, about the FXO card entering a non-operational
state. While in a call, all of a sudden, there's this loud noise, and
the card remains like that until I reload the wcfxo module. There's no
way to dial in or out the FXO unless the module is reloaded.

I made some progress... I was looking for an indication in the system
that the problem was occurring. Well, I found it. When the FXO "blows
up" asterisk gets the following event:
WARNING[213006]: Detected alarm on channel 1: Red Alarm

Last night I was talking on the FXO extension, and it happened. Just
to confirm, I went to /var/log/asterisk and looked at the messages
file. There it was: the freaking Red Alarm.

I noticed that the Red Alarm also happens when I unplug the phone
line. When I plug it back, there's this notice:
NOTICE[229390]: Alarm cleared on channel 1

I'm wondering if it's the FXO that causes the problem, or if it's the
line that puts the FXO in the inoperable state. I don't know if it
makes any difference, but the line is connected to a PBX, not directly
to the telco.

So, instead of shutting down asterisk, reloading the module, and
starting asterisk again, I will take a look at the drivers source to
see if I manage to make it self-restart when it detects the Red Alarm.

Any thoughts? Suggestions?
