To view the voice mail via phone user interface:

The LCD screen displays the amount of new and old voice mails.
2.
Select an account and then press the Connect soft key to listen to voice mails.
The SIP-T21(P) E2 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 slow 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-T21(P) E2 IP phone only
handles the MWI messages sent from the server. But for other servers, the MWI service
is solicited, so the SIP-T21(P) E2 IP phone must enable subscription for MWI.
Note
