Refer to the exhibit A user takes a phone from San Francisco to New York for a short reassignment. The phone was set up to use the San Francisco device pool, and device mobility is enabled on the Cisco UCM. The user makes a call that matches a route pattern in a route list that contains the Standard Local Route Group. To where does the call retreat?

A. The call fails because the Standard Local Route Group is being used only if no configuration is set for the device pools

B. The call egresses in New York because the device automatically is assigned a New York device pool and uses the local gateway

C. The call fails because device mobility is turned on. and the phone is not configured in New York The engineer must configure which sites the device should be roaming to

D. The call egresses in San Francisco because the user uses device mobility and is allowed to roam while still keeping the number and resources assigned in San Francisco
