Message Waiting Indicator (MWI)
The SIP-T40P IP phone supports MWI when receiving a new voice message. If someone leaves
you a voice mail, you will receive a message waiting indicator. MWI will be indicated in three
ways: a warning tone, an indicator message (including a voice mail icon) on the LCD screen, and
the power indicator LED slowly flashes red. This will be cleared when you retrieve all voice mails
or delete them.
The MWI service is unsolicited for some servers, so the SIP-T40P IP phone only handles the MWI
messages sent from the server. But for other servers, the MWI service is solicited, so the
SIP-T40P IP phone must enable subscription for MWI.
