• The first task in Cisco's 'MWIs Do Not Turn On or Off' procedure is to run the Check Telephony Configuration test, reachable from Related Links on Telephony Integrations pages. in context
• For SCCP integrations that have two or more port groups, Cisco notes that not all port groups may be configured correctly, which is a listed cause of MWI delay. in context
• Checking 'Force All MWIs Off for This Phone System' and saving turns off all MWIs for that phone system integration. in context
• Cisco's MWI checklist requires confirming that MWIs are not forced off at the phone system level. in context
• Cisco's MWI checklist requires confirming that the port groups in the integration have MWIs enabled. in context
• For some phone systems integrated through PIMG/TIMG units, Unity Connection must turn an MWI off on the same port that turned it on; if a different port is used, the MWI-off request fails and the MWI stays on. in context
• On phone systems that need port memory, deleting or reconfiguring voice messaging ports can cause MWIs to turn on but not turn off. in context
• Cisco's MWI checklist requires confirming that voice messaging ports in the phone system integration are assigned to send MWI requests, that those ports are enabled, and that enough ports are so assigned. in context
• Whether MWI is enabled for a user is checked with the Enabled check box at Users > Users > Message Waiting Indicators in Cisco Unity Connection Administration. in context
• Cisco's MWI checklist requires confirming that the correct phone system is assigned to the user's MWI. in context
