/mcpThis section describes the interface changes in Cisco Unified JTAPI to handle the interactions when an address is added to a conference by using click to conference feature. When click to conference feature is used, consult call does not occur and Cisco Unified JTAPI applications do not receive CiscoConferenceStartEv or CiscoConferenceEndEv. The feature can be disabled by turning off the “ENABLE CLICK TO CONFERENCE” CallManager service parameter. Interface Changes CiscoFeatureReason, on page 408 Message Sequences Click to Conference, on page 1092 Backward Compatibility This feature is backward compatible. No change in Cisco Unified JTAPI applications when this feature is not configured or used. Cluster Abstraction The CTIManager provides a virtual representation of all the Cisco Unified Communications Managers in a cluster. Cisco Unified JTAPI applications communicate with the CTIManager instead of with a specific Cisco Unified Communications Managers. The CTIManager also maintains connection between Cisco Unified Communications Managers in a cluster. This allows a provider to represent any devices in the cluster under the CTIManager. Figure 4: Single-Box Configuration with JTAPI, Cisco Unified Communications Manager, and CTIManager in One Box, on page 61 illustrates “Figure 4: Single-Box Configuration with JTAPI, Cisco Unified Communications Manager, and CTIManager in One Box, on page 61.” Figure 5: Redundant Cisco Unified Communications Manager and CTIManagers with JTAPI Deployed as a Separate Client, on page 62 illustrates “Figure 5: Redundant Cisco Unified Communications Manager and CTIManagers with JTAPI Deployed as a Separate Client, on page 62.” For more details about the cluster administration and device pool settings, refer to the Cisco Unified Communications Manager help information.
