VM calls not disconnecting with new SIP to Analog adapter

VM calls not disconnecting with new SIP to Analog adapter

VM calls not disconnecting with new SIP to Analog adapter

(OP)
Help me out here guys, It's been a while since I dealt with this but just went from POTS lines to SIP>Analog converter(grandstream) and the calls are having an issue disconnecting after a calling party hangs up. Is it just the Disconnect Clear that I need to lower well below 500ms?

Also, the Grandstream device default is 200ms. The provider had it at 500ms however, do we want the Grandstream device lower than the Avaya or vice versa?

RE: VM calls not disconnecting with new SIP to Analog adapter

IPO should be lower than the POTS line. Gives it a better chance or recognizing it.

Any particular setting? I have the IPO set to 250ms and the adapter set to 500ms right now. Leave a VM and watching the call on system status and it's still not disconnecting.

RE: VM calls not disconnecting with new SIP to Analog adapter

Which Grandstream device are you using? Are you using this to connect SIP trunks to Analog Trunk Ports in your IP Office control unit? Or is this to connect analog extensions over SIP to your IP office?

Do you have "disconnect supervision" enabled?

Please & thank you!

RE: VM calls not disconnecting with new SIP to Analog adapter

Put a butt set on it and make sure it is actually sending the disconnect. I don't know what vendor I was working with but they were adjusting the time and didn't have it turned on. Turned on and boom... it worked.

It's an 8 port grandstream ATA, the SIP terminates on the device and then analog to the IPO
Here are some other settings. I'm curious about the loop current disconnect setting that isn't enabled

I believe I have it fixed, I did enable that Loop Current Disconnect on the Grandstream device and I also set the Grandstream to 800ms with the IPO @ 350ms.

RE: VM calls not disconnecting with new SIP to Analog adapter

Loop current disconnect sounds like it was probably the right answer to turn on. Pink for posting resolution.

The truth is just an excuse for lack of imagination.

RE: VM calls not disconnecting with new SIP to Analog adapter

That is kinda what I told you. I knjow some adapters the disconnect is off by default. Seems stupid they would do that, but guys who design IP stuff really aren't phone guys... wink
