Message Waiting Indicator
You can configure the Message Waiting Indicator (MWI) to illuminate for a specific line or for all lines. For example, if you
configure the MWI LED on line 3 only, the LED illuminates if a voice mail is pending on line 3. If you configure the MWI LED
for all lines, the LED illuminates if a voice mail is pending on any line on the phone (lines 1 through 9).
You configure the MWI indicator using the Aastra Web UI.
