If your phone monitors another extension, a red light indicates that the extension is in use.
Flashing red means that it is ringing.
Tap the extension line to dial that person. This can be used to place a call to them or initiate a transfer.
BLF for Shared Voicemail
If your phone has a line configured for Shared Voicemail, a red light indicates that a message is waiting.
