When there is a failure of the Cisco Unified Communications Manager CTI Manager service in a
high-availability design, a contact center agent with a call in progress sees which behavior with the
PIM /LOAD 0 option enabled?

A.
High-availability design means that there is no change of behavior visible to the agent.

B.
Call remains in progress; however, the CTI Desktop and Cisco IP Phone have no call control.
When call completes, the agent’s CTI Desktop is set to Not Ready after the failover is completed.

C.
Call will be terminated while Cisco IP Phone reregisters to alternate Cisco Unified
Communications Manager CTI Manager service.

D.
Call remains in progress, but when call completes, the agent’s IP Phone reregisters with the
backup subscriber and the agent must restart the CTI Desktop software.
