An engineer configures several calling party transformation patterns in Cisco UCM so that calling numbers are shown in the +E.164 format.

The calling transformation on the SIP trunk is applied first, and then the calling transformation on the route patterns is applied.

B.

Calling transformations cannot be configured on both route patterns and a SIP trunk.

C.

The calling transformation on the route patterns is ignored because there is already a calling transformation on the SIP trunk.

D.

The engineer must also apply a calling transformation at the route group details level.

The admin does not want to add more route patterns other than the current 9 prefix for the gateway to the Cisco UCM. How must the Cisco UCM be configured to meet the requirements?

A.

Configure two CSSs. then add a translation pattern with the secondary CSS to send calls with 9713 to the secondary gateway.

B.

Configure two partitions and two CSSs, then add a translation pattern with the secondary CSS to send all calls with 9713 to the secondary gateway.

C.
