CallLogEx

To support switchover, the CallLogEx attribute is updated with values that would normally be assigned to the CallLog attribute.

Since the CallLog attribute is treated as an append-only attribute, this caused an issue with the Switchover Interaction Resiliency feature, because the CallLog attribute was replicated from the primary server to the backup server. Each update resulted in an append operation instead of a set operation, which caused the CallLog to be skewed for interactions that existed at the time of a switchover.

The CallLogEx attribute resolves this. If an update includes the CallLogEx attribute, the value should be set as the value of the CallLog attribute.

Specifically, when interaction updates are replicated to the backup server to support the Swithcover Interaction Resiliency feature, the CallLogEx attribute is updated instead of the CallLog attribute.
