Softkeys and Programmable Keys
Softkeys as Busy Lamp Field (BLF)
You can set a softkey to Busy Lamp Field (BLF).
The BLF feature on the IP phones allows a specific extension to be
monitored for state changes. BLF monitors the status (busy or idle) of
extensions on the IP phone.
Note: The BLF setting is applicable to the Asterisk server only.
Example
A Supervisor configures BLFs on his phone for monitoring the status of a
worker’s phone use (busy or idle). When the worker picks up his phone to
make a call, a busy indicator on the Supervisor’s phone shows that the
worker’s phone is in use and busy.
On the 55i, the busy and idle indicators show on the IP phone screen
display next to the softkey programmed for BLF functionality. When the
monitored user is idle, an icon with the handset on-hook shows next to the
BLF softkey. When the monitored user is on an active call, a small
telephone icon is shown with the handset off-hook.
Note: You can also use the BLF configured softkey to dial out. Contact your system
administrator for more information.
