I was reset to the factory the phones more times.
But this hostname https://dm.yourwhc.co.uk/dms/phone is come back into Server URL section after reset to factory.

The default password is ok on the phone and on the WEB UI.

The Server URL is overwritable and I can write to my server hostname. And the phones are joining for my server.
If I just restart (reboot or unplug and plug back) the phones, has no problem. The problem has if I resetting to factory the phones. The URL field data is come back to https://dm.yourwhc.co.uk/dms/phone.

The phones has Internet connection. And doesn't connect to any provider No service and doesn't overwrite the default admin password after reset to factory.

I think the MAC addresses of the phones are registered somewhere with a provisioning server (RPS).
Maybe Yealink support can help release these MAC addresses.
