A company has a headquarters site and a remote site. Cisco Unified Communications Manager acts as a DHCP server. Both sites use their local voice gateways for PSTN calls. At the headquarters site, the PSTN prefix is 9, and the emergency number is 911. At the remote site, the PSTN prefix is 0, and the emergency number is 112. Here are the deployment policies for roaming devices: Softphones can roam between two sites. A roaming softphone uses the local gateway for all PSTN calls. The user keeps home dial habits on a roaming softphone, with the exception of the emergency number. When a headquarters user uses a softphone at the remote site, prefix 9 can be used to make PSTN calls via voice gateway in the remote site, but emergency number 112 does not work. Which setting on CUCM should be checked?
A) DHCP Subnet
B) Device Mobility Info
C) Physical Location
D) Device Mobility Group

Device Mobility Info should be checked because it determines the behavior of devices when they roam between different locations, including the adaptation of dial plans and emergency numbers.
