Add Busy Lamp Field Keys

With 8x8 Busy Lamp Field (BLF) keys, you can monitor the busy status of a shared extension user or pick up calls intended for a Group Call Pickup, or parked on a Call Park extension within the same phone system. BLF keys are physical keys on a desk phone or hardware endpoint that light up to show when there is an active call for a monitored extension. An executive assistant can monitor calls intended for their boss. They can tell when their boss is not available, and pick up the important calls for them.

In addition to the number of keys on the physical phone, sidecars can optionally be added to some models in order to extend the number of BLF keys. BLF keys are created in Configuration Manager and then pushed to the desk phone. You can add as many BLF keys as your device allows.
