Refer to the exhibit.

In a Cisco Unified Contact Center Enterprise system, callers have reported that their calls are
dropping intermittently without hearing any greetings or queue music. At times they are able to
hear Cisco Unified IP IVR prompts but are then dropped before connecting to an agent.
The Cisco Unified Communications Manager is configured as follows for this deployment:
All CTI Route Points that make requests to Cisco Unified ICM have names that start with “IPCC.”
All CTI Route Points used for Cisco Unified ICM Translation Routing to the Cisco Unified IP IVR
are named starting with “Trans.”
All CTI Ports used by the Cisco Unified IP IVR are named starting with “CTI.”
All Agent Phones are named starting with “SEP.”

There is concern about how these devices are associated in the Cisco Unified Communications
Manager configuration. The device associations for the PGuser and IVRuser are shown in the
exhibit.
Given the problem and the current device associations, what two things might be causing these
call failures? (Choose two.)

A.
“Enable CTI Application Use” is not checked on the PGuser and IVRuser configurationoptions

B.
The Peripheral Gateway and Cisco Unified IP IVR do not use the PGuser nor IVRuser Cisco
Unified Communications Manager user accounts

C.
CTI_1300 and TransRtPT3 should not be associated with the PGuser Cisco Unified
Communications Manager user account

D.
All devices should be associated with both the PGuser and IVRuser Cisco Unified
Communications Manager user accounts

E.
The Agent IP Phone 3001 should not be associated with the IVRuser Cisco Unified
Communications Manager user account

F.
The problem is not with the configuration. The Cisco Unified Communications Manager
database subscription is broken on subscribers
