[asterisk-users] Red alarms

[Wayne Jensen]

Asterisk is getting red alarms on my T1, sometimes once or twice a
day, but today it happened 5 times.  Even once is too many.  Every
call in progress is dropped.  Please help!  What do I need to do?
What can I try?  I've googled and searched this list and can't find
anything.  Here's an example from the logs:

Here are other items that appear in the logs quite frequently that I
think are related (and probably all related to timing):

Feb  7 15:52:13 WARNING[8920] chan_zap.c: Ring/Off-hook in strange
state 6 on channel 4
Feb  7 15:52:21 WARNING[2524] chan_zap.c: zt hook failed: Device or
resource busy

We also get ghost calls from time to time.

The telco told me that timing must be provided by us, but when I tried
that all hell broke loose.
