Analog Unsupervised Disconnect issue 3

[DiscLight]

We have 4 analog lines from Century Link and they do not have Supervised Disconnect so when calls are on either transfer to cell, conference call or just leaving a voice mail the lines are getting hung up and will not disconnect from the Avaya IPO 500v2 version 9.1.

For som reason Century Link does not offer Supervised or Reliable Disconnect. I have tried the suggestion to get the Avaya to detect disconnect but no luck.

We use call transfer to cell phones a lot and we have to manually use SSA to disconnect the lines after every transfer.

Does anyone have any other suggestions I can try?

Keep hassling Century Link. They can do it... Just the kids they have for tech support don't know how to do it. There are a lot of names for the same function. I assume these are internet lines. I have had to go round with several internet analog lines providers to find out what their routers call it but they can all do it. It is a basic function of analog lines.

I would agree, I also assume this to be some type of sip ata and most if not all can do some type of cpc drop of loop current now a days.

Believe it or not these are legacy POTS lines that have been installed since 1970 right from the utility poll to a CLNK demarcation punch down block.

Clink can do it. You just have to get the right person. We still have pots at some customers directly from the CO on copper that are from Brightspeed/old Clink and I know for sure they can do disconnect supervision. Any provider can do it, you may just need to go up the chain though.

 

[DiscLight]

I will.

In the meantime is there any settings I can use to disconnect the lines after a hang up?

try the below config on IPO and test.
System >> Telephony Tab >> Tones&Music subtab

I do believe that the copper it's self has been there since the 70's. But the CO equipment has probably been recently upgraded since the 70's era equipment has died. I have tried to use the Busy Tone Detection with limited success.

I was having issues with proper disconnect on a Fibre to POTS device. I noticed that when the far end disconnected first the Fibre/POTS device provided busy tone. Checking the box for System -Telephony-Unsupervised Analog Trunk Disconnect Handling fixed the issue. When you check the Disconnect Handling box the Busy Tone Detection box as noted by @Mo. Abdullah above is automatically checked and greyed out.
I now get reliable disconnect everytime.
