On 6865i IP phone, the programmable key LEDs illuminate either flashing, solid, or turn off depending on the state of the
monitored extensions. On the 6867i and 6869i, the BLF states are indicated by the color of the softkey button on screen
(red of busy, yellow for ringing, and green for idle) as well as the LED indicators (i.e. solid for busy, flashing for ringing, and
off for idle).
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” are dynamic and the Mitel IP phones are automatically updated without requiring
a restart.
