Busy Lamp 
Field (BLF)
Associates a 
programmable key with 
an extension that can be 
automatically dialed when 
selected; the key’s light 
indicates that the 
extension is busy and 
blinks when ringing.
The BLF ring tone is 
played only when the 
phone is in idle state. It is 
stopped when the 
destination phone stops 
ringing or the local phone 
exits idle state.
When multiple BLF 
extensions ring 
simultaneously, the IP 
phone will play the first 
BLF extension ringer and 
beep tones and ignore 
other BLF extensions.
• Must be configured by the system 
administrator.
• The BLF feature can be assigned 
only to internal extension 
numbers, not outside numbers. 
• The feature is not available in 
BASIC mode.
Call Log Shows the history of 
incoming calls, up to 99.
• Pressing the Enter button will 
dial the number displayed. If 20 
seconds pass without any input, 
the phone exits the Call Log.
