Busy Lamp Field (BLF)
You can use BLF to monitor a specific line for status changes on the phone. For example, you
can configure a BLF key on the phone to monitor the status of a friend’s line (busy or idle). The
BLF key LED glows red when the friend’s line is in use.
You can also enable visual and audio alert features for BLF pickup on the phone.
You can use the BLF key to do the following:
 Placing a call to the monitored user
 Transferring a call to the monitored user
 Pick up an incoming call of the monitored user
 Parking a call to/retrieving a parked call from the monitored user
Configuring a BLF Key

also initiate an outgoing intercom call to the monitored user, or assign a pick up code for BLF
key first to pick up an incoming call of the monitored user. Check with your system
administrator to find out if these features are available on your phone.
