Disconnect - stuck in mailbox for 3 minutes 1

[onlinecomputerservic]

-
When a call comes in and makes its way into the mailbox of a user, even if they only leave a 5 second message, the line sits open and active for 3 minutes.

It is as if the 'Disconnect Clear' isnt working properly although it has been enabled for each line.

When I use System Status, I see the calls is just waiting around, killing time....until 3 minutes, then it disconnects. When the call finally disconnected, the user recieved the email notice.

If the caller press the "#" key, after they leave a message, the email sends immediately, then prompts them to mark as private or asks them to disconnect. The calls still waits in the queue for 3 minutes.

If the caller hits the "#", the call will disconnect immedaitely.

I am using IP 406 4.0(7)

Any idea what is going on and how I might fix this?

May be worth getting your Line provider to also check there disconnect clear timers also.

Is there a specific question I ask? Do I ask if timers are on? or set to a value? Will they even know what I am asking ?

The IPO is connected to 6 normal anaolog lines.

Thanks

Just enquire as to what your Disconnect timer is set to.

QUOTED from A BT document (Sorry not sure what country your in)

DISCONNECT/CLEAR TIME
The disconnect clear time is a disconnection of the A&B wires to the PBX subscriber. It is variable in 100 m/s steps from 0 to 1 secs. The actual parameter is P16 of DSB resource. The disconnect/clear time is used by PABX's either to enable it's equipment to release or, to inform the PABX that the exchange line has recognised that the call has come to an end. There are two Problems that have come to light with regards to the disconnect/clear times, these are:

* No dial tone. This occurs if the disconnect time is too long, the problem is that the has cleared and is ready to seize an outgoing line but System X still has the disconnect/clear condition on the line i.e. the line is disconnected hence no dial tone.
* Phantom calls. This occurs because of the way some PABX's detect I/C calls. When the PABX has cleared and is ready to receive an I/C call it monitors the A & B legs. System X puts out a test condition onto the line after the disconnect/clear time to check whether the PBX is on or off hook. This test condition is recognised by some PABX's as an I/C call.

Because of the wide variety of PABX's in the field it is very difficult to obtain exact figures for dis/clear times. Even on the same type of PABX you can have different Software and Firmware Packages which use different dis/clear times. However as a general rule the dis/clear time is set to 800 m/s, but if difficulties occur either with Phantom calls or NDT this time should be reduced.

I have my "Disconnect Clear" currently set at 1000.

( I am in Canada )

You need to set the disconnect clear timer on the IPO to abot 150ms LESS than the value set by your line provider. Your next step is to validate with your line provider whether disconn clear is set on your lines and if so what value they have assigned to it

Take Care

What type of dial tone?

 

[onlinecomputerservic]

I am not sure what type, what types are there? Ours sounds like a typical North American type.

Is there a setting in IP Office Manager that I could see and change.

If you mean signalling type, I have it set on DTMF.

Thanks

How is the dial tone being provided?

 

[onlinecomputerservic]

5 basic analog telephone lines

Who is the provider?

 

[onlinecomputerservic]

Aliant, which is now part of Bell

Call in from the outside,answer then put the call on hold. Have the person calling in hangup. See how long it takes to disconnect the line using status.

 

[onlinecomputerservic]

Ok, done, here are the results:

I called in with my cell phone, I put the call on hold. then hung up with my cell.

The called stayed connected and then after about 2 minutes, my phone rang back to remind me I had a call on hold.

When I look at the Trunck Summary, I see the current status of that line is "Holding".

Then, after about 2 more minutes it calls me again, resseting the timer each time but never dropping the calls.

Arghhhhh.....Now what ???

Set you "Disconnect Clear" to 400 ms and do the cell phone test again.

Disconnect has been set to the following:

10
100
300
400
800
1000

and still, the system doesnt recognize that the callers has hung up....

Trunk Type: Loop Start ICLID
Signaling: DTMF Dialing
Direction: Bothway
Bearer: Any
Imedance: blank

Does that help?

Tell provider you need a "supervised" or "positive" diconnect. Each provider calls it something different. Don't be suprised when the first person you talk to has no idea what you are talking about. Ask for the next level up.

Well, after hours and hours and hours with my telco, I think 1043 is correct, the issue is with the type of service I have. Apparently, I have a Centex Express services. This is basically an analog line without high end features. Basically, they cripple the features to force you to buy the more expensive, key system specific lines. I think the new features are called ACS, automatic call distribution and that is what will give me the Supervised Disconnect that I need.

Thanks to everyone for their great ideas and input. I will post back after the lines are installed.

Cheers,
Chris

Yippieeee !!!

I am happy to report that the upgrade to the new Centrex lines (Key Friendly) has done the trick...again thanks everyone..

Cheers,
