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 illuminates solid red when the friend's line is in use. For more
information on BLF key LED indicators, refer to LED Instructions on page 14.
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.
To configure a BLF key via phone user interface:
1. Press Menu->Features->DSS Keys.
2. Select the desired DSS key.
