Actual exam question from Cisco's 300-815

Question #: 197
Topic #: 1

An engineer configures several calling party transformation patterns in Cisco UCM so that calling numbers are shown in the +E.164 format. The route patterns match seven-digit internal numbers and prefix the numbers with 1408. The SIP trunk matches 1408XXXXXXX and prefixes the number with +. When users make outbound calls, the calling number still shows as seven digits. What is the cause of this problem?

A. 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.
