Deskphones don't show as provisioned but can be restarted from web

[AGidi]

Hello guys have an odd issue.

We have a bunch of Yealinks T38G, that don't show as an available phone on the 3CX WebClient for the user, but does ring when you click to dial or dial from Web

They do not show as provisioned on the 3CX management Phone console, but if I press Restart, the phone does restart.
Plus some are duplicated or triplicated.

I tried adding the MAC address to the Phone on the management console, and copy paste the provision link via STUN to the phone which was TRUSTed option disabled.

Any ideas on how to troubleshoot this? all opinions suggestions are welcomed. thanks

Hello @AGidi

Please note that these phones are EOL and do not support uaCSTA CTI that is why they are not visible in the web client. They ring using client because Push is enabled on that extension.

Also the only thing i can see in the Phones tab that is not quite right is that the same phone shows up twice which could be because you have 2 devices under the same extension.
The phones show up correctly provisioned with their mac address so that is not an issue.
