The SIP-T20P/SIP-T20 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 prompt message (including a voice
mail icon) on the LCD screen, and the MESSAGE key LED illuminates solid green. This
will be cleared when you retrieve all voice mails or delete them.
The MWI service is unsolicited for some servers, so the SIP-T20P/SIP-T20 IP phone only
handles the MWI messages sent from the server. But for other servers, the MWI service
is solicited, so the SIP-T20P/SIP-T20 IP phone must enable subscription for MWI.

MWI service is not available on all servers. Contact your system admini strator for more
information.
