One of our client has configured the GXP1625 in constraint mode. He also unable to provide the admin password of the device.
I can get access to the phone using the Ethernet cable directly to the phone and my laptop. I also have the access to the phone’s web GUI as a user.
But I can’t change the setting as a user or perform factory reset to the device as I don’t have the admin access to the device.
How can I resolve this problem???
