I have a recurrent problem on my asterisk box. I have "VIA Samuel 2"
as a
CPU. With asterisk v11.1.0 and dahdi-linux-complete-2.6.1+2.6.1 compiled
from source.
I get a RED alrm drom the port 1( FXO) two or three times per day:
[Feb 4 15:54:57] WARNING[9991]: chan_dahdi.c:8018 handle_alarms: Detected
alarm on channel 1: Red Alarm
I plug the RJ11 in a normal phone and I can hear the line is up and I can
call extern number (via PSTN)
I must stop asterisk + restart dahdi and start asterisk to get asterisk
work normaly. I have no idea where is the problem or even what to do to
debug the issue
I get these outputs when the channel is in "RED Alarm"
