Message Waiting Indicator (MWI)

The SIP-T56A smart media phone supports MWI when receiving a new voice mail. 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 touch
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-T56A smart media phone only
handles the MWI messages sent from the server. But for other servers, the MWI service is
solicited, so the SIP-T56A smart media phone must enable subscription for MWI.
Note MWI service is not available on all servers. Contact your system administrator for more
information.
