Cisco CallManager

Cisco Cisco Unified Communications Manager clusters only: Before you activate this service, verify that the Cisco Cisco Unified Communications Manager server displays in the Find and List Cisco Cisco Unified Communications Managers window in Cisco Cisco Unified Communications Manager Administration. If the server does not display, add the Cisco Cisco Unified Communications Manager server before you activate this service. For information on how to find and add the server, see the Cisco Cisco Unified Communications Manager Administration Guide.

Cisco Cisco Unified Communications Manager clusters only: If you deactivate the Cisco CallManager or CTIManager services in Service Activation, the Cisco Cisco Unified Communications Manager server where you deactivated the service no longer exists in the database, which means that you cannot choose that Cisco Cisco Unified Communications Manager server for configuration operations in Cisco Cisco Unified Communications Manager Administration because it does not display in the graphical user interface (GUI). If you then reactivate the services on the same Cisco Cisco Unified Communications Manager server, the database creates an entry for Cisco Cisco Unified Communications Manager again and adds a "CM_" prefix to the server name or IP address; for example, if you reactivate the Cisco CallManager or CTIManager service on a server with an IP address of 172.19.140.180, then CM_172.19.140.180 displays in Cisco Cisco Unified Communications Manager Administration. You can now choose the server, with the new "CM_" prefix, in Cisco Cisco Unified Communications Manager Administration.
