Unsolicited Notification
Both Cisco Unified CME and Cisco Unified Communications Manager in SRST mode can use the
unsolicited mechanism for generating MWI notifications. With this mechanism, the MWI notifications
will reflect the accurate status of messages in a subscriber’s voice mailbox.
The unsolicited option does not require Cisco Unified CME to send a subscription request for each
ephone-dn to Cisco Unity Express for MWI notifications. Cisco Unity Express sends Notify messages
to Cisco Unified CME whenever the voice mailbox for any ephone-dn receives a new message. In this
way, the MWI status reflects the current voice mailbox message status.
To use the unsolicited option, Cisco Unified CME must configure each ephone-dn that is registered to
receive MWI notifications as follows:
