their mailbox without calling the mailbox. IP phones support both audio and visual MWI
when receiving new voice messages. MWI will be indicated in four ways: a warning
tone, an indicator message (including a voice mail icon) on the LCD screen, the power
indicator LED slow flashes red and the MESSAGE key LED lights up (MESSAGE key LED
is only applicable to SIP-T29G/T27P/T23P/T23G/T21(P) E2 IP phones). For more information
