extension is not found following v20 update

[connortp]

I am extension 000 on our system, but since updating to v20 (from v18) last week my extension is 'not found'.

I'm not able to receive direct calls or calls from ring groups.

I am still able to make calls from my extension.

Any help or suggestions on why my extension is now behaving badly would be appreciated!

Hi there.
If you log into the Phonesystem as a system owner user and search for that extension, can't you find in the Users section?

Thank you

Hello @OlegR_3CX

Yes, I'm able to login to the admin console both with extension 000 and my email address for that extension.

Are you able to receive the calls from another internal extension directly?
What are you using on 000 to receive the calls, is it a 3CX Web client or a Mobile application?

Thank you

My extension rings briefly but then doesn't. This behaviour happens on both my yealink T46G and my yealink W52 dect phone.

I'm not able to directly receive a call internally - behaviour as above.

I am able to make calls internally and externally without any issues

Did you pass the firewall checker (Dashboard >> Troubleshooting >> Firewall) on your PBX?

Hi. Just ran this again and yes everything passed ok.

The system is hosted on Azure and was installed via the PBX Express route a couple of years ago.

Everything goes via a SBC in our office. All other internal extensions on the SBC are working as expected. It's just 000 experiencing the weirdness.

I can not think of something other than a networking issue between the Phonesystem and the remote site.
If you only use the 3CX mobile app and via the DATA network, do you face the same issues when calling another app also that is connected via the DATA network?
