Message Waiting Indicator (MWI)

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. MWI will be indicated in three ways: a warning tone, an indicator
message (including a voice mail icon) on the touch screen and the power indicator LED slowly
flashes red. For more information on power indicator LED, refer to
145.
IP phones support both solicited and unsolicited MWI.
Unsolicited MWI
Unsolicited MWI is a server related feature. 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.
Solicited MWI
For solicited MWI, you must enable MWI subscription feature on IP phones. IP phones support
subscribing the MWI messages to the account or the voice mail number.
