Configure BLF on SNOM


Busy Lamp field (BLF) feature allows users to monitor several other extensions.

Idle state – LED is off
Ringing state – LED is blinking
Busy or Connected state – LED is on
The "Call Pickup” function is usually configured together with BLF allowing, for example, a receptionist to pickup ringing calls with a press of a single button.
