On the 9133i 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 480i 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
480i screen next to a softkey
button. The softkey icons on the
screen change depending on the
state of the extensions. On the
9133i running Broadsoft firmware,
the programmable key LEDs
illuminate either flashing, solid, or
turn off depending on the state of
those extensions.
Asterisk BLF Configuration
You can enable the BLF feature on
Asterisk to enable monitoring for
specific extensions. BLF on
Asterisk is possible through the
“hint” extension parameter.
Add the following in the Asterisk
extensions.conf file for each target
extension being monitored.
For example:
exten -> 9995551212,hint,SIP/
9995551212
Add the following in the Asterisk
sip.conf file for each subscriber if it
is not defined already.
For example:
[9995551212]
Subscribecontext=sip
BroadSoft BLF Configuration
You can enable the BLF feature on
BroadSoft BroadWorks Rel 13 or
higher through the BroadWorks
Web Portal. Each user must have
the Busy Lamp Field service
enabled for their user. The user
must add each desired extension to
the “Monitored Users List” on the
Busy Lamp Field service page and
also enter in a list name for the
monitored users BLF list on the
same page.
Changes to the “Monitored Users
List” is dynamic and the Aastra IP
phones are automatically updated
without requiring a restart.
Reference

Settings”
