And connection was still running until I reset VG.

 

Interesting is that this connection was not recorded in CDR. I recorded it in my DB logs

 

in at 2012-03-07 23:59:14

transfered at 2012-03-08 00:00:31

 

Connection data in logs available.

 

What happens when connection started before midnight and continuing to new day?

GCEV_BLOCKED is an ISDN message that indicates that the channel itself is now blocked.

 

It usually happens when the ISDN D-channel is dropped, and hence all the channels on the trunk go into 'BLOCKED' state.

 

You can see in the trace excerpt supplied that all the channels are receiving the BLOCKED event at the same time - consistent with D channel failure triggering this:

 

001348.532 19 2 1 ev Dialogic 2098,GCEV_BLOCKED, crn=0, 2098,0,0,,,

001348.532 19 4 2 ev Dialogic 2098,GCEV_BLOCKED, crn=0, 2098,0,0,,,

001348.532 19 7 3 ev Dialogic 2098,GCEV_BLOCKED, crn=0, 2098,0,0,,,

...

(these events will go on for all channels)

 

D channel drop can be caused by wiring problem, or (in very rare occasions) by Telco switch resetting the ISDN trunk.

 

Looks like this happened just after midnight, so may be telco was carruying some maintenance on the trunk?

 

Once the D channel is back up all the channels on the ISDN trunk will receive the "UNBLOCKED" message and they will all go back into service.
