You can use BLF to monitor a specific line for status changes on the phone. For example,
you can configure a BLF key (line key) on the phone to monitor the status of a friend’s
line (busy or idle). The BLF key LED flashes red when the friend's line receives an
incoming call. For more information on BLF key LED indications, refer to
LED Instructions

You can press a BLF key to dial out the monitored phone number when the monitored
line is idle. You can receive a visual or/and an audio alert (if enabled), and also pick up
calls that are received on the monitored line. For more information, contact your system
administrator.
