Don’t Want the Backlight Active When BLF Status Changes
Last modified date: 2019/06/16 Views: 2553

In V81 firmware version, Yealink phones set BLF changes status (red/green) accompany with backlight activated as default since many of our customers asked us to enable this feature as default. (BLF status changes activate the backlight), so that they can easily notice the status of monitoring extension by the change of backlight.


However, some customers don’t want this behavior and ask for a way to disable it.



Please set this parameter via Auto provision.


features.blf_active_backlight.enable = 0
