The correct answer is A. The call egresses in New York because the device automatically is assigned a New York device. Device Mobility in CUCM allows a phone to dynamically adopt a new device pool based on its current IP subnet. When the phone is plugged in at the New York location, its IP address falls within the New York subnet, so CUCM assigns it the New York device pool. The Standard Local…
Question
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?

- CThe call fails because the Standard Local Route Group is being used only if no configuration is
- DThe call fails because device mobility is turned on. and the phone is not configured in New York

Explanation
Device Mobility in CUCM allows a phone to dynamically adopt a new device pool based on its current IP subnet. When the phone is plugged in at the New York location, its IP address falls within the New York subnet, so CUCM assigns it the New York device pool. The Standard Local Route Group then resolves to the local route group defined in the New York device pool, causing the call to egress through the New York gateway. This is exactly the purpose of Device Mobility combined with the Standard Local Route Group-enabling roaming users to use local PSTN breakout automatically without manual reconfiguration.
