After VM Pro transfer, analog calls not disconnecting although caller hang-up

[sanniadnan]

Hi All, We’ve IP Office SE (version 11) Primary, Secondary, Application Server and 500v2 with 4 analog 500 ext mo 16.

If calls coming from analog trunks and incoming route set to direct extension then before pick up the calls (in ringing state), if caller hang-up the calls then it disconnects as usual.

But in VM Pro I’ve been facing an issue. In VM Pro menu where it plays welcome greetings and tell caller to press extension directly or dial 0 to talk with operator, the problem is when calls come from analog trunks to VM Pro and transfer to an extension, during ringing if nobody pickup the calls and caller hang-up then it keeps ringing unlimited times on the extension. In system status application I can see trunk is occupied although original calls have been terminated.

In line setting “Disconnect Clear” is set to 500ms. I’m not sure it has anything to do as it is working when calls land from incoming route to extension from analog trunks. Calls from IPTSP to same VM Menu have no issue.

Need your valuable suggestion as I'm kind of new in Avaya IP Office. Thanks.
Adnan

who is the analog truck provider? Sounds like reliable disconnect is not activated on their end.

It's BTCL, only land line provider in Bangladesh.

Its possible reliable disconnect/disconnect clear is not enabled or they have it set lower then you have set for your line. If you look at help in manager it shows your lines should be at least 150ms lower then what the provider has it set to. You can call the provider and see if they have it set and what it is set to (most providers nowadays have no clue what you are talking about sadly). You can also try lowering the time and see if it helps (try 100 lower at a time). Those are really your options.

The truth is just an excuse for lack of imagination.

Simple way to test is with a butt set. Place a call, listen for the click when you hang up. If you don't have a butt set you can use a voltmeter set on DC. You should see the momentary drop in voltage at the end of the call.

If this is the same system and issue as

https://www.tek-tips.com/viewthread.cfm?qid=1800782

then don't start a second thread in which you reveal information that you've withheld from the original thread.

The chances of people being able to help you is not helped if you withold key system details and start multiple threads!!! This is most likely an analog trunk disconnect issue - check and fix that first.

Hi sizbut, this is not the same issue.

 

[sizbut]

Several people in this thread have told you it is a reliable disconnect issue. They are correct. Your other thread is a reliable disconnect issue. You created this without resolving the original problem. Attach as trace of incoming analog trunk call being disconnected by the system (by the IP Office system, not the original caller) and I might belive you. Until then listen to people and fix the analog trunk settings, not the voicemail.

Hi sizbut, several people told me that it's a reliable disconnect issue, I didn't disagree that. Even I've mention that on my initial post. I'm working on it as suggested by critchey and budbyrd.

Can you read again my other thread? teletechman confirmed that avaya is build in that way. That is not an issue, now people is trying to give me some tips to way around to achieve that requirement. I don't know why you are linking that to this one?

The actual scenario is totally opposite of what you understand. Original caller disconnected the calls but ip office system showing call is active state and calls is ringing to extension unlimited time.

Why don’t you try and lower the disconnect time on your line from 500 to 360 ms and see if that helps..

What is the disconnect clear time from your carrier.
Recommended to lower the Ipo timer by 140 ms from the carrier timer

 

[sanniadnan]

Hi snowman50, Thanks for your reply. I've asked to the carrier but they don't know what the value they have set! To lower the disconnect time, 500v2 is asking to reboot. Client isn't allowing me to reboot right now. Have to wait till weekend.
