Enable Device Mobility,
perform one or both of the following subtasks:
Perform these procedures as
needed for your configuration. You can configure Device Mobility to be enabled
across your cluster, for individual devices, or a combination of enabled and
disabled for devices.
|Step 2||Configure a Physical Location
Configure the geographic
location so that your system can determine which network resources to assign to
a device. If a user moves away from the home location, the system ensures that
the device uses local media resources and the correct bandwidth for the call.
|Step 3||Configure a Device Mobility Group
Configure the device
mobility group to define a logical group of sites with similar dialing patterns
(for example, US_dmg and EUR_dmg). Depending on the network size and scope,
your device mobility groups can represent countries, regions, states,
provinces, or cities. For example, an enterprise with a worldwide network can
choose device mobility groups that represent individual countries, whereas an
enterprise with a national or regional network can define device mobility
groups that represent states, provinces, or cities.
|Step 4||Configure Device Mobility Information
Configure device mobility information such as the subnets and
device pools that are used for device mobility. When a phone registers, your
system compares the IP address of the device to the subnets that are configured
device mobility in the
Device Mobility Info Configuration window. The best
match uses the largest number of bits in the IP subnet mask (longest match
rule). For example, the IP address 184.108.40.206 matches the subnet 220.127.116.11/24 rather
than the subnet 18.104.22.168/16.
|Step 5||Configure a Device Pool for Device Mobility
Manager assigns a device pool to an IP phone based on the device's IP subnet.
The following steps describe the behavior:
phone tries to register to Unified Communications Manager by sending its IP
address in the registration message.
Communications Manager derives the device's IP subnet and matches it with the
subnet configured as part of the device mobility information.
subnet matches, Unified Communications Manager provides the device with a new
configuration based on the device pool configuration.
