Solved Yealink T43U - No Service & Account Unregistered

[Henson]

I am using 3CX hosted and have provisioned IP desk phone (Yealink T43U) as router phone.
On the IP desk phone shows no service and warning account unregistered.
The desk phone has latest firmware 108.86.0.70
Can anyone help or give any light how to resolve this issue?

Thanks

Hi Alejandro,
Thank you for your advised.
I have updated the FW to 108.86.0.76. Some reason auto provision doesn't work properly so I manually enter provisioning link, Auth ID, password and account detail in the phone via web console then restart the phone,
Now the phone is working as it should be.
Thank you so much for your help

Glad to know it is resolved.
Please always ensure that the phones are running on the latest 3CX Supported Firmware version to avoid this situation.
