Message Waiting Indicator (MWI)
The SIP-T54S media 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-T54S media IP phone only handles
the MWI messages sent from the server. But for other servers, the MWI service is solicited, so
the SIP-T54S media IP phone must enable subscription for MWI.
Note
Voice mail access codes must be predefined on the system server. Contact your system
administrator for the more information.
MWI service is not available on all servers. Contact your system administrator for more
information.
Before listening to voice mails, make sure the voice mail access code has been configured.
When all new voice mails are retrieved, the power indicator LED will go out.
