Why does Service Level View show an IPT application as Down in a Cisco Unified Communications Manager cluster to which the application is not even registered?
When changing an IP telephony (IPT) application’s registration from one Cisco Unified Communications Manager cluster to another, you must remove the registration of the IPT application to the old Cisco Unified Communications Manager cluster in both the IPT application and the old Cisco Unified Communications Manager cluster. If you do not do this, registration of the IPT application with the old Cisco Unified Communications Manager cluster will continue to appear in the Service Level View in the Down state.
