An administrator needs to ensure that calls beginning with +1 are routed out the
London gateway only if the Redmond gateway is unavailable. Which set of
changes should the administrator make to the voice configuration?

A) Create a new route called US_Fallback that will route calls starting with +1 to the London gateway. Create a new PSTN Usage called Fallback_Usage and add it to the voice policy Global_VoicePolicy. Configure the PSTN Usage Fallback_Usage to have a lower priority than Global_Usage.
