Using BLF to Determine a Line State

Busy Lamp Field (BLF) features 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.

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.

Tips

•Your phone may 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.
