Dear AST-BSD list...
My current asterisk1.4.4/zaptel1.4.1 PBX, has a problem.
Sometimes, all comunications from the zap channel, are
getting dropped.
in the logs, i see things like this:
Jun 5 12:34:36 pbx kernel: wcte11xp: Setting yellow alarm
Jun 5 12:35:11 pbx kernel: wcte11xp: Clearing yellow alarm
and in asterisk i see:
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Detected alarm
on channel
1: Red Alarm
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Unable to
disable echo
cancellation on channel 1
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Detected alarm
on channel
2: Red Alarm
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Unable to
disable echo
cancellation on channel 2
...
[Jun 5 12:34:36] NOTICE[52644] chan_zap.c: PRI got event:
Alarm (4) on
Primary D-channel of span 1
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Detected alarm
on channel
21: Red Alarm
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: No D-channels
available!
Using Primary channel 16 as D-channel anyway!
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Unable to
disable echo
cancellation on channel 21
[Jun 5 12:34:36] WARNING[52644] chan_zap.c: Detected alarm
on channel
22: Red Alarm
and then
[Jun 5 12:34:47] WARNING[52644] chan_zap.c: No D-channels
available!
Using Primary channel 16 as D-channel anyway!
[Jun 5 12:35:11] NOTICE[52644] chan_zap.c: Alarm cleared on
channel 1
[Jun 5 12:35:11] NOTICE[52644] chan_zap.c: Alarm cleared on
channel 2
[Jun 5 12:35:11] NOTICE[52644] chan_zap.c: Alarm cleared on
channel 3
after the alarm are cleared, PBX comes out, and ppl can make
calles
again.
The telco says its a problem comming from the PBX. They are
monitoring
the comunications, and they see a "LOFT" alawm
signal comming from the
PBX.
Im pretty lost here, as im not really an expert.
If anyone can give me an advice about this, it woule be
greate!
In the meaning time, im buying a Sangoma A101, and crossing
the fingers
its a bug in the digium hardware.
This problem, present like 2-3/day.
thanks in advance.
Phillip
