Busy Lamp Field (BLF)
The Busy Lamp Field (BLF) is a feature that lets you monitor calls.
When the BLF service is available, you can assign the BLF function to a feature key. The phone treats a
BLF feature key-press as a speed dial to call the monitored extension.
The following table lists typical BLF events, the operations that happen when the event occurs, and the
LED pattern for that event. Two or more events can happen at the same time, but the LED pattern shows
only one event at a time.
