Message Waiting Indicator (MWI) informs users of the number of messages waiting in
their mailbox without calling the mailbox. IP phones support both audio and visual MWI
when receiving new voice messages.
IP phones support both solicited and unsolicited MWI. Unsolicited MWI is a server
related feature.
IP phone sends a SUBSCRIBE message to the server for message-summary updates.
The server sends a message-summary NOTIFY within the subscription dialog each time
the MWI status changes. For solicited MWI, you must enable the MWI subscription
feature on IP phones. IP phones can subscribe the MWI messages to the account or the
voice mail number.
IP phones do not need to subscribe to message-summary updates. The server
automatically sends a message-summary NOTIFY in a new dialog each time the MWI
status changes.
