Extensions that suddenly don't work.

Extensions that suddenly don't work.
PBX version 18.0 (Build 1865) cloud 3CX.
Pbx activated on 06/23/2021
Suddenly after a few days of activation, an extension is no longer able to make and receive calls.
The extension is paired with a call queue, along with other extensions, which ring regularly.
Only calls between extensions work.
I tried to delete and recreate the extension, keeping the same parameters, but it didn't solve the problem.
I have created a new extension, with a new numbering and this works correctly.
Today in the same Pbx, the same problem has arisen for another extension.
I have created a new extension, with a new numbering and this works correctly.
Best regards.

Hi @SalvoMic !

Could you please tell us what you have registered to your extensions? Are you using IP Phones (if yes, are they SBC or STUN), Mobile apps, WebClient, the new Windows App?

Also, you say you are not able to make/receive calls. So just to try and rule out somethings, please confirm that all the following scenarios fail:

• To another extension
• To and External Number
• From another extension directly (not going through a Queue)
• From an External Number (via the Queue)

Could you please leave at least one extension that exhibits this behavior on the system so we can check?

As soon as the same problem arises, I will contact you.
Thanks for collaboration.
