What should the TEHO-US route list configuration consist of?

Refer to the exhibit.

The exhibit shows centralized Cisco Unified Communications Manager configuration components for TEHO calls to U.S. area code 408 from the U.K. The PSTN
access code for the U.K. is 9 and 001 for international calls to the U.S. What should the TEHO-US route list configuration consist of?

A.
First route group should point only to the U.K. gateway. The second route group should point to the U.S. gateway.

B.
First route group should be only the local route group. The second route group should point to the U.S. gateway.

C.
First route group should point only to the U.S. gateway. The second route group should be the local route group.

D.
The TEHO-US route list should contain only the local route group. The globalized configuration means that the appropriate gateway will be selected
automatically.

E.
The \\+! route pattern should point directly to the U.S. gateway.

Explanation:
Incorrect answer: A, B, D

The route group points to one or more gateways and can choose the gateways for call routing based on preference. The route group can serve as a
trunk group by directing all calls to the primary device and then using the secondary devices when the primary is unavailable. One or more route lists can point to
the same route group.
