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. When the monitored user is idle, there is a small telephone icon
shown with the handset on-hook. When the monitored user is on an active call, a
small telephone icon is shown with the handset off-hook.
Example
A receptionist has a 55i running Broadsoft firmware that subscribes to a list of
extensions from the BroadWorks Application Server. On the 55i, the 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.
