i posted this in the t1 forum but i thought i would also post something here for the asterisk gurus out there.
we have a turn key asterisk pbx with a digium t1 card and it has been dropping a number of calls over the last two days and we're not sure what the cause is.
we had a verizon tech come on site yesterday to test the pri and he said that he was seeing a timing issue. he recommended that we restart the pbx which eliminated the issue but he only tested for a minute after the restart so i'm not convinced that there isn't some other issue. before we restarted the pbx he actually told me that he noticed a number of errors on the circuit but he wasn't sure if they were related to the timing issue.
we're still seeing the circuit drop and the log will occasionally show a number of the following messages in it:
254 05/24/2009 2:20 PM NOTICE chan_zap.c: PRI got event: Alarm (4) on Primary D-channel of span 1
255 05/24/2009 2:13 PM NOTICE chan_zap.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1
256 05/24/2009 2:13 PM NOTICE chan_zap.c: PRI got event: HDLC Abort (6) on Primary D-channel of span 1
257 05/24/2009 2:13 PM NOTICE Last Message Repeated 4 times
i've done some research and from what i can find these errors are related to the hardware/irq of the asterisk box but most people that i found with similar errors did not report dropped calls or alarms on the t1.
i've opened another ticket for our provider to do some intrusive testing on the circuit but i wanted to check if anyone else had a suggestion on how to stop this?

The original post is from 2009. Hopefully the issue has been resolved.
