Busy Lamp Field - Avaya 1165E User Manual

Additional features

Busy Lamp Field

The Busy Lamp Field (BLF) feature is an alternate presence-monitoring mechanism for the IP
Deskphone that allows presence functionality on proxies that support BLF.
BLF is an icon state for a corresponding Speed Dial key on an IP Deskphone; the icon state
tells you if another extension connected to the same SIP server is busy. You do not enable or
disable this feature; BLF is configured by your system administrator. If enabled, the IP
Deskphone subscribes to the proxy and receives the presence state list for all the users it is
configured to watch. Call states and the corresponding presence icons are shown in the
following table:
State
Unknown
Terminated
Ringing
On the phone
Note:
If you have the required permissions, you can answer a call placed to a monitored IP
Deskphone. To answer, press the flashing Ringing button.
