Yealink Router Phones not provisioning

[Matt_AIT]

We have a bunch of Yealink t46U's as Router phones. The SBC part is showing as online but no extensions will provision. They all show disabled next to registration status on the phone UI, and all appear as new phones in the phones tab in the management console.

We have tried factory resets and settings up the router phone fresh but the status stays disabled.

Is the firmware current? https://www.3cx.com/docs/phone-firmwares/

Did you configure the phones as Router Phones from the Admin Console, or the Management Console?
(Router Phones have to be configured from the Admin Console)

If the phones are properly setup as Router Phones, their IP will be something like 192.168.1.7:41887 (instead of 192.168.1.7:5060) in the phones section.

Current firmware should be 108.86.0.77.

same issue here: router phone works fine in 96.86.0.74 as soon as I upgrade to 96.86.0.77 as the recommended firmware it has exactly that issue. SBC part works . no extension registers.
