please hang up

[joelunchpail]

I replaced an 8x24 and flash with a 0x32 and a Call Pilot and added an auto attendant and ccr tree.
All seemed to go well . Except now I get the occasional message left: ( beep beep beep please hang up the phone etc.)in the GD mail box and one of the clerks MB.
I checked for disconnect supervision. I shortened the disconnect timer to 260 ms, and later to 100 ms.
None of the real messages left appear to have disconnect problems, or the please hang up the phone message attached at the end.
I changed the trunk cards. or at least swapped them.
The new trunk cards are nt7b75'S the old 8x24 trunk cards were nt5b40's but were never auto answered by the flash.
On the old system the trunks never hung and left this message in any mail box but as i said were never auto answered.
I am having a problem getting my head around this.
Any ideas would be appreciated.
I'm not quite ready to blame the TelCo

I usually do 2 tests for disconnect supervison. First I test the nortel side. Make a phone call from a phone on the system from a certain line to someone, put that person on hold and have them hangup. Now count how long it takes the line to drop from the phone system. Personally if it drops anywhere between 10-15sec its working fine, its not a disconnect issue.

If it doesnt drop from the system within that time I check the voltage levels from telco and from there you will know if the problem is with telco or with the phone system. Just be sure to test EVERY line cause it could be just 1 bad apple.

LS Supervision is usually left at 460 ms.

For each line.
Check - Norstar Trk/Line data - Trunk Mode - Super (OSI) or Unspr (default)turns Disconnect Supervision off for the line.

I just did a test call, AA answered and I hung up. - disconnected at 11 seconds.

(Joe Lunchpail- I have one of the original INCO Pillows. A Lunchpail made by Lemay Mfg. in Sudbury, ON Canada. For some reason they started making a larger one too. The size just happened to correspond to the length of a welding rod.)

It is definitely beginning to look like a Telco problem.
While testing : if I hang up as soon as the AA answers the call is not released until it goes through the AA, CCR Tree, and defaults to reception , 4 more rings and goes to the GD Mailbox and eventually times out, leaving a lot of blank VMail messages.
It was probably happening on the old system prior to the conversion.
The addition of the AA and CCR has probably extended the time enough to initiate the "please hang up" message.

Even if you've turned on DS in your system doesn't mean it's enabled at the CO. Request the telco check it.

 

[joelunchpail]

The telco says DS is not available, the system and whole town is on a line concentrator via radio link, I can,t remember which concentrator it is, (SR100) or something like that.
I did install one years ago and if I remember correctly the documentation stated the lines mimicked a cable pair , whatever happened on one end was duplicated on the other end including the voltage and frequency for ring generator.
I will probably have to get hold of their Engineering dept, and hope they still have an old engineer. Failing that talk their Programming dept to at least try and program the line for DS in spite of what they think.

In the past we have used a ground start OE in the CO optioned as a loop start to simulate the disconnect open. Also, have used a payphone OE to achieve the open(I think this was on a SR500). Not sure how accommodating your telco will be.

Viking sales a CPC 1, call party control, that you can use to solve this problem they might have a multiple input unit.

Interesting??

how programmable is it?

it sounds as though it might cause more complications by hanging up when it shouldn't , as my not hanging up when it should problem is now.
I am still trying to get hold of a telco guru to see if he can fix his end.

the other answer would be to not send any calls to a mailbox unless caller actually makes some selection in the ccr.
possibly an information MB instead of GDel MB , then exit.

Is it possible to have the default after the ccr tree go to (hang up) instead of repeat or attendant.

 

[joelunchpail]

I can set a trap for hangups if I turn off Gen Del Mailbox and make the attendant not available . If the caller doesn't stay on the line and choose an option in the ccr tree the incoming call defaults to (EXITING the system ) and the Call Pilot Disconnects immediately.
The only issue I see is that people will not be able to press "0" for the operator without being dumped.
But I can give them other choices to get to the Operator if they choose to listen.

Yes you could use CCR to get to an attadenat i.e press 1.
Then go to /Table/Atdnt/ change to 000 so then when they press 0 it does nothing.

Nortel has gone through a lot of trouble to make it difficult to hang up on incoming calls.
They do allow the CCR to be an Info Menu only, but there is no option to continue from there to a normal sub menu home menu.
I thought possibly using the alternate language press 9 but I believe I would still be stuck in the INFO MB.
Turning off the ATDNT and the GDMB seems to be the only solution that works, and It will work Fine.
