Busy Lamp Field
With the Busy Lamp Field (BLF) feature, you can monitor the call status of other phones
connected to the same network.
Important:
BLF lines are not call appearance lines and cannot be used to make calls.
This feature is available in both Broadsoft and Asterisk environments. See the environment
specific information in notes.
Depending on the configuration, you can use BLF lines for specific tasks, such as:
• Monitoring the activity status of the phone
• Receiving incoming calls for another user (Directed Call Pickup)
• Speed Dial of the BLF user in an idle state
• Viewing outgoing call status
• Barging in on an active call
• Unparking a call (available only in the Broadsoft environment)
You can also assign BLF users to pre-configured line keys.
Note:
In the Broadsoft environment, you can change BLF line mapping on the Phone screen but not
edit the BLF list.

BLF configuration
Depending on the environment, the system administrator can configure the BLF feature in either of
the following ways:
•
46xxsettings.txt
file (available in the Broadworks and other Open SIP environments).
For Broadworks, use the
46xxsettings.txt
file only if Broadsoft Xtended Service
Interface (XSI) is disabled. When XSI is enabled, phone will retrieve the BLF configuration
from the Broadworks server and ignore the BLF parameters in the
46xxsettings.txt
file.
