initial value = 5
i want 15
It's ok to modifie but when he move the phone peo in a another room the config is cancel
Have you a method for modifie permatly parameters of this phone
The phones are probably receiving this parameter from a provisioning server every time they reboot.
To change this permanently, you would need to delete the link with the provisioning server from the phones (if you are not actually using it anymore to make changes on the devices), or you would need to modify the backlight parameter on the server directly, so that the phones get it set to 15 every time they reboot and get the provisioning.
Please refer to the following FAQ in order to understand how snom phones handle setting changes:
