Chapter 1 Product Overview
Features
Communications Manager node used by the primary Cisco Unified Attendant Console Advanced
server fails, another Cisco Unified Communications Manager takes over and the primary Cisco
Unified Attendant Console Advanced server continues to run.
• Primary CTI Manager on Publisher fails (partial failover).
• BLF Server fails (partial failover).
• If you remove all Queue DDI or CT Gateway devices using Cisco Unified Attendant Console
Advanced Administration (partial failover). For example if Queue DDIs are manually removed from
the TSP User Profile, the server remains active but calls follow the call forward set on Cisco Unified
Communications Manager to the Subscriber. You can still update the system configuration using the
Cisco Unified Attendant Console Advanced Administration on the Publisher.
• TSP failure.
• Database failure.
• Cisco Unified Attendant Console Advanced server failure (or server shut down, or failure of the
communication channel between the Publisher and Subscriber servers).
During a partial failover some or all of the primary Cisco Unified Communications Manager system
devices go out of service. However the primary Cisco Unified Attendant Console Advanced server on
the Publisher server continues running because the TAPI-based CT Link continues working.
