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.
