Yealink T19P registration failed

[novatel]

Hello,
after V16 upgrade and updating Yealink T19 phones with last FW 53.84.0.35, some of them failed to register. The only options i have are Add/Assign ext and reject:


None of them is working for me- the phones stayed unregistered.
Any ideas?

I would try to factory reset one of the phones and see if that makes a difference.

Hello @novatel

the phones in the screenshot look like they are not provisioned. You may want to also download the new Yealink templates from the update section if you haven't already and reprovision the devices.
Also check the IP blacklist in case the devices were blacklisted by accident

Hello Yiannis,
all new updates are already downloaded. the phones are provisioned, see the respond below:


also i tried to delete the extension and apply it again, but no success. The problem is that i cant connect to the phone remotely even via vpn. IPs are not blacklisted.

If you are on the side of the PBX and you cannot reach the phones via the VPN then the PBX might be not be able to reach them either. Have you tried factory resetting a phone to see if that makes the phones reachable?
