Core Issue
The Message Waiting Indicator (MWI) does not turn off sometimes if MWIs have lost synchronization. MWIs may lose synchronization if, for example, the phone system is off-line when an MWI status changes.
Resolution
Use this procedure to fix the issue:
- From the Windows Start menu on the Cisco Unity server, select Programs > Cisco Unity > Manage Integrations. The Cisco Unity Telephony Integration Manager (UTIM) appears.
- For the integration node, click the Properties tab.
- In the MWI Synchronization section, click Resynchronize Now.
- If applicable, check the Resynchronize At check box, and choose the time that you want the system to resynchronize the MWIs. Cisco recommends choosing a time outside of regular business hours because of the Cisco Unity resources needed for resynchronization.
Beyond this basic resynchronization check, there are numerous possible problems causing MWI on/off problems or delay. Search for "MWI" to see other solutions within TAC Case Collection (TAC CC). For all other issues with MWI, refer to these documents:
