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
VP-T49G/SIP-T29G/T27P/T23P/T23G/T21(P) E2 IP phones). For more information on power
