Introducing Device Mobility

3.If the device pool in the phone record matches the device pool in the matching subnet, the system considers the phone to be in its home location, and the phone retains the parameters of its home device pool.

4.If the device pool in the phone record does not match the device pools in the matching subnet, the system considers the phone to be roaming and subject to reregistration and reapplication of device parameters. Table 19-1describes the possible conditions that can arise and the system responses.
