MICS not releasing lines

[deanyed02]

Here is the scenario:

MICS release 7.1, Call Pilot 150. Both new systems. A total of 9 analog lines into system. All but lines 7 and 8 are AA answer. (lines 7 and 8 are branched out for another business) What happens is periodically, the CallPilot will not release the lines and all 7 line will lock up. If you select them on a phone, the display reads reads "in use CP" which is the Call Pilot DN. C.O. says reliable disconnect is implemented on lines and timing is correct. In order to clear the lines, we simply pull them off the 110 block and re-terminate them. Clearing the first line or two resets all of them. This is not on a consistent basis, as the MICS and Call Pilot are working fine otherwise. They had an old NAM voicemail, which we thought was causing the problem, and suggegsted an upgrade to Call Pilot. The new install was fine for a few weeks, and now this issue happens again maybe once(twice at the most) a week. Customer is getting frustrated. I have been over line settings inside and out, and spoken with other tech support, but cannot determine a cause for the lines not releasing from VM. Any suggestions?

Change your SUPY on the Norstar lines to NO

I think Perry means supervision to Y.

Sounds like a Disconnect Supervision problem.
Norstar only supports OSI Disconnect Supervision.

Here's an easy way to test to see if Telco is providing you with DS.

Assign the line to appear and ring on a Norstar set.
Have somebody call you, and then place them on hold.
Have the caller hang up.
When they hang up, the flashing held line indicator should disappear immediately, (within 30 seconds from some Exchanges).
If it disappears immediately you have Disconnect Supervision.

It turns out that the C.O. did NOT have reliable disconnect on their trunks. We tried to verifiy this first thing, weeks ago, and they kept saying "Yes" they did. It wasn't until I actually tried to get the time settings that they admitted they were wrong. Telco has since implemented Open Loop Disconnect on all lines. I will monitor the changes and Post back if this was not the fix.

And yes, lines should be Supervised.

Thanks for the posts.

telcos are good at that. they put the monkey back on your back to prove it is their problem, especially with intermittent problems.
