Fanvil phone provisioning issue

[Newbee]

Hello All,

When I am doing auto provisioning with Fusionpbx and Fanvil ( X5u and X7)phone and sending display brightness timeout functions,
fanvil_display_brightness_active
fanvil_display_brightness_inactive
fanvil_display_inactivity_time


Those settings are not applying to the phone.
Does anybody know how to do setup those?
