I have a T48S that a client wants to re-use with 3CX
However we have tried to reset to factory and it does its thing and resets from the LCD , but when it restarts, it re provisions and we can't login to remove the auto provisioning.
no one knows the Admin password.
The unit just will not co-operate.

All my other 48S units work fine on the reset.
Does anyone know how I can get around this issue

Hi,

Please factory reset the phone without internet/network connection.
After reboot, try to log in with the default admin password?
Can you log in? Yes, then the phone's MAC-address is locked to an RPS somewhere. You have to contact the reseller and ask to remove the MAC-address from that RPS.
If the phone is provisioned from your 3CX then the admin password can be found there. (3CX Phone extension)

Kind regards,
Frank.
