Can't add or modify any extension or ring group

[CCS-Stephane]

We have been using this PBX for a while and never had an issue. it's running version 16.0.6.636, hosted in Azure.

Starting this morning, every time I try to add or modify an extension or a ring group I get the following error:
(500)
An item with the same key has already been added

I've tried different browsers, different computers, restarted all the services on the PBX, same issue.

Any idea would be appreciated.

Hi.
Did you resolve this? - I am seeing the same issue on our PBX, also hosted in Azure.

Hi Stephane,

You should try to update to the final build which is 16.0.6.641 because you are on a beta version now that was not meant for production use.

The error message was also showing a key and we noticed that the key was actually one of the phone numbers on the SIP trunk.

Deleting and recreating the inbound rule associated with that specific phone number resolved the issue for us.

Thanks - same for me.

Hi all,

We released an update which should resolve the issue with editing extensions:
https://www.3cx.com/blog/releases/v16-update-6a/

Please check it out and confirm whether it resolved the issues you were facing or not.

Does not help my case. I just installed a new pbx, a week ago, until now I was able to edit extensions. Today I installed the 6a update and now I get the 500 error. The same happens when I try to edit a trunk. The error shows the main trunk Number.
I deleted the trunk, then created it again. That fixed the problem.
Why?
