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 9143i and 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.
You can configure a BLF/List key on the IP Phones using the configuration files
or the Aastra Web UI. You can also specify a BLF list URI that the phone uses to
access the required BLF list. You can specify a BLF List URI using the “
list uri ”
parameter in the configuration files or the BLF List URI field in the Aastra Web
UI at the path
Operation->Softkeys/Programmable Keys/Expansion Module
Keys->Services->BLF List URI . For more information about the “list uri”
parameter, see Appendix A, the section, “BLF List URI Settings” on page A-218 .
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.
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.
