CallPilot not disconnecting CO lines

[tekunishan]

Here a weird one...
I have a customer with a BCM 400, Rls:3.0 Build: 7, MB modules are as follows: DSM32+, CTM8, CallerID Trunk Interface (4) and a GATM8.
Lines on CTM8 = 151-154/159-162 CID4 = 167-170
The issue I am having is as follows:
All lines are set up in CallPilot to answer on 0 rings, table 1 (CCR 1). When I call their main #, I reach the AA (no problem), the greeting plays as usual for approx. 30 seconds. After that, I remain on the line to timeout to the Atdt DN: 255. The line rings her, everything works fine. However, if I call into the main number, reach the AA, then hang up while the greeting is playing, the same amount of time lapses (30 sec), then x255 rings. When she answers the call, she hears "If you'd like to make a call, please hang up and try again..."
Can I assume from this recording that the CO is seeing a disconnect, but the CallPilot/BCM is not. I think I ran into this a long time ago on the old StarTalks. Any help would be appreciated, sorry for the lengthy post

you have no disconnect supervision check the trunk programming and check your pots lines...should be able to check with butt set make call hang up wait oh about 5 sec...if still no dialtone "directly off demarc" then its a telco issue.

Trunks are set up as Supervised, Manual Answer Mode. So you are saying to put my butt set on a line at the demarc, make the inbound call, hang up, and after approx. 5 seconds, I should get dialtone back. I will give this a try the next time I am on-site. The customer informed me that this issue has happened before, but cleared up, with no one touching the BCM programming. I will post back near future, thanks for the reply.
