Message Waiting Indicator (MWI) is a feature that informs users that they have
messages waiting in their mailboxes. This feature indicates how many messages are
waiting without the users having to call their mailboxes. The IP phones support both
audio and visual MWI when receiving new voice messages.
The IP phones support both solicited and unsolicited MWI. Unsolicited MWI is a server
related feature.
Solicited MWI: MWI notification is subscription-based. The 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 the IP
phone.
Unsolicited MWI: MWI notification is not subscription-based. The IP phone does not
need to subscribe for message-summary updates. The server automatically sends a
message-summary NOTIFY in a new dialog each time the MWI status changes.
