Operational IP Phone Features
BLF\List Setting
(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 in 
ringing state, there is a small bell icon shown.  When the monitored user is on an 
active call then a small telephone icon is shown with the handset off-hook.  
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.
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.
Example
A receptionist has a 57i running Broadsoft firmware that subscribes to a list of 
extensions from the BroadWorks Application Server.  Each monitored extension 
in the list shows up individually on the 57i screen next to a softkey button. The 
softkey icons on the screen change depending on the state of the extensions. 
On the 53i running Broadsoft firmware, the programmable key LEDs illuminate 
either flashing, solid, or turn off depending on the state of those extensions.
