Voice Mail Message Waiting Indicators for Cisco Unified Communications Manager (CUCM)
Perform the following tasks from the Voice Mail Waiting Indicators window:
Refreshing the Message Waiting Indicator
The MWI is a light indicator on a Cisco IP phone to notify the phone user that a voice-mail message is pending.
Occasionally, the MWI setting for a telephone can be out of synchronization with the user's message status in the voice-mail database. For example, a user could have pending messages, but the MWI would not be turned on. You can refresh the MWI light so that the light reflects the current message status in the voice-mail database.
Use this procedure to refresh the message waiting indicator (MWI) for a single mailbox or for all mailboxes.
Step 1 Choose Voice Mail > Message Waiting Indicators > Refresh.
Step 2 To refresh one mailbox, check the box next to mailbox owner's user or group ID and click Refresh Selected. To refresh all mailboxes, click Refresh All.
Modifying Message Waiting Indicator Settings
Use this procedure to modify message waiting indicator settings.
Step 1 Choose Voice Mail > Message Waiting Indicators > Settings. The SIP MWI notification mechanism window appears. Select one or all of the following:
- Subscribe Notify —Cisco Unified Communications Manager subscribes to Cisco Unity Express using SUBCRIBE/NOTIFY SIP messages for MWI notification for each of the ephone-dns registered to receive MWI notifications. See MWI Configuration Examples.
– Check the box to include envelope information in the notifications.
- Unsolicited Notify —Cisco Unified Communications Manager is not required to send a subscription request for each ephone-dn to Cisco Unity Express for MWI notification. Cisco Unity Express sends NOTIFY SIP messages to Cisco Unified Communications Manager whenever there is a change in the MWI status for any ephone-dn.
Step 2 Click Apply to save your settings.
