Phone Configuration for Monitoring Other Phones
You can configure the phone to monitor the status of lines on other phones. This feature is useful if users
routinely handle calls for colleagues and need to see if they are available to answer calls. The phone monitors
each line on a separate line key. The monitoring line keys function as Busy Lamp Field (BLF) keys. A BLF
is an LED that changes color to indicate the status of the monitored line:
