50 Model 53i IP Phone User Guide
Line Keys and Programmable Keys
BLF List Key
(For use with the BroadSoft Broadworks Rel 13 or higher platform only)
The BLF\List feature on the IP phones is specifically designed to support the
BroadSoft Broadworks Rel 13 Busy Lamp Field feature.
This feature allows the IP phone to subscribe to a list of monitored users defined
through the BroadWorks web portal.
In addition to monitoring the idle and busy state, the BLF\List feature also supports
the ringing state. On the 53i phone, the LED lights next to each BLF programmable
key illuminate steady to indicate the monitored line is off-hook or unregistered. The
LED goes off when the is idle. When the monitored extension is ringing, the LED
flashes.
Example
A receptionist has a 53i running Broadsoft firmware that subscribes to a list of
extensions from the BroadWorks Application Server. On the 53i running Broadsoft
firmware, the programmable key LEDs illuminate either flashing, solid, or turn off
depending on the state of those extensions.
Note: Your System Administrator must have BLF List enabled on the Broad-
Works Server. Contact your System Administrator for more information.
Note: You can use a BLF\List configured key to dial out.
Note: The Broadworks BLF feature is not the same as the Broadworks Shared
Call Appearance (SCA) feature and does not permit call control over the
monitored extension.
