Norstar 6x16 Phone system was just installed, have a CP100 hooked up to it. System worked fine in the lab with lines hooked up to it, however when it was installed in the customer’s site I’m not experiencing something very strange?? When calling the main number the CP picks up & answers fine with the main message, press 3 to leave a message in a general greeting mailbox. Customer presses option 3 and the call is transferred out to the correct mailbox, however once the customer finishes leaving the message it looks like the Norstar won’t drop the call.

It doesn’t seem as though I’m getting a positive disconnect from telco. I watch line one remain off hook for about 1 minute and then the line clears down. (This is also happening to my other 2 lines as well) When I try making a call outbound from the Norstar I get the same thing. After I make the call outbound, I connect to the far end finish the conversation & hang up. The phone system shows line 1 with an active call for 1 min or so. I put my butt-set on the telco pairs & listened to the call process take place. I hear CP answer & route the call properly, I’m also able to hear the customer leave the message in the General MB & they hang up. The call continues to stay off hook and the call connection is never dropped. I remain on the line and what appears to be a telco message “your call did not go through, press 0 for the operator, then I receive a worble tone & eventually the call drops. This is a strange one?? I have a call in with telco to see if they can check the lines, is there a timer setting maybe in the phone system to drop the call? Thanks in advance, 95% finished :confused:

Have to set ds supervision up in lines, Is it DR5?-----John

Well a 616 is not compatible with Callpilot and I wouldn't put any voice mail on a 616 unless it was a DS version.

Wrong customer this one is a 4x16 compact ICS with 7.0 software (sorry)

Still need to set up DS under lines.-----John

John, I thought I had that set for lines 1-3 & It was still doing the same thing?

Craigers99, If system worked correct on bench, then only thing different is line disconnect supervision? Different CO office? Are the lines out of channel bank on site or pots?-----John

John,
I will be contacting Telco this morning to find out what's going on. Yes it is coming out of a different CO.. Lines are just regular pots.

Craigers99, Discon timer may not match CO settings,can raise or lower at CICS.-----John

John,

Funny, I was just reading that in the manual. There's like 5 different Millisecond settings.
60,100,260,460, or 600. I think 460 is the default?? Maybe I will try to change it to 60 or 100 to see if it makes a difference.. I will check tonight & let you know.. Thanks for the info!!!
