Using BLF to Determine a Line State
Busy Lamp Field features (BLF) allow you to view the state of a phone line that is associated with a
speed-dial button, call log, or directory listing on your phone. If you use BLF Pickup, you can answer
a ringing call for the line that you are monitoring. Your system administrator determines which BLF
features are configured for your phone.
Tips
• Your phone might play an audible indicator to alert you when a call is ringing on the monitored
line (BLF Pickup only).
• BLF Pickup answers the oldest ringing call first (if the line that you are monitoring has more than
one ringing call).

a coworker’s phone Press the BLF Pickup button while the line is ringing.
The call is redirected to the next available line on your phone. (If you want
to specify a line, first press a line button, then press the BLF button.)
If your phone supports auto-pickup, the call connects automatically.
Otherwise, the call rings on your phone for you to answer.
Note If you press the BLF Pickup button when the monitored line is not
ringing, your phone will speed dial the line number.
