MWI is namely Message Waiting Indication. Messaging Waiting Indication is a common
feature of telephone networks. It typically involves an audible or visible indication that
messages are waiting, such as playing a special dial tone (which in telephone network is
called message-waiting dial tone), lighting a light or indicator on the phone, displaying icons
or text, or some combination (draft-ietf-sipping-mwi-04.txt).
Vigor IPPBX 2820 supports MWI feature. With this feature, when someone leaves you a
voice message, a special tone (MWI tone) will be played while you pick the phone up. This
implies that you have a voice message. After listening such special tone, you will hear the
normal dial tone. Then you can choose to listen to the voice message or call someone back.

Here, we use the following illustration to make an example for using MWI.
Generally, Jacky uses mail client to receive voice mails. But it’s not convenient to check
voice mail via mail client at all times. Especially there is a possibility that voice mails may
be dropped or deleted by an accident due to Antivirus scan. To avoid it, Jacky also uses
MWI feature of Vigor
IPPBX 2820 to inform himself of missed phone calls.
