I am posting this in the IP Office and the CS1000 sections hoping to get some insight from everybody.
Avaya IP Office V2 – 8.0(16)
Nortel Option 11C – Succession 3.0
Got both systems tied together via T1 PRI using QSIG. Option 11C loop is setup as ESIG while the IP Office is setup as QSIGB.
Incoming PRI is on the Option 11C. The option 11C has no console phone and is always set in night sending all incoming calls (on loop 5) to an avaya hunt group (480) (on loop 7). Within the hunt group 480 is a single extension x387 which is the console phone. Thus far all daytime activity with this setup works.
Night service is setup on the IP Office. Console phone has a night button that sets the hunt group (480) into night service. The night service fallback group is set to go to hunt group (606) which has a single phantom user (x607) which is set to forward unconditional to a phone on the option 11C side (x211).
Our problem seems to only happen when the IP Office is put into night service. A call comes in to x480 on 1 channel and is automatically forwarded over another channel to x211 holding up 2 channels for the duration of the call. Randomly the call will not disconnect and it doesn’t allow anymore calls to come in until its cleared even though there are 21 other channels free.
STAT of loop 7 (PRI between the 2 systems) on the option 11C shows all channels idle. Viewing the channels on the IP Office via system status shows 2 channels in call state. Manually disconnecting the call via system status in the IP Office clears the channels and normal operation resumes.
We are leaning on it being a protocol disconnect problem but having a hard time finding where to look. Any suggestions would be greatly appreciated.
Thanks
Damon
