Chapter 19 Cisco CallManager Device Mobility

Introducing Device Mobility

Device Pools

After the device mobility groups and physical locations are identified, you can associate them with device pools. Each device pool contains the set of parameters that apply to devices, and adding the device mobility group and physical location ties the device pool to those entities.

Device Mobility Information

In the final step in designing a device mobility structure, you associate subnets with the device pools that contain the device mobility group and physical location information. When a phone registers and obtains an IP address, the system compares the address to device mobility subnets that are associated with one or more device pools. The matching subnet becomes the device home subnet for the purpose of device mobility.

Phone Configuration

After the device mobility structure is in place, you can turn device mobility on for IP phones that are provisioned to be mobile.

Device Mobility Process

This section describes how Cisco CallManager manages phone registration and assignment of parameters for device mobility.

Following initialization, the Device Mobility feature operates according to the following process:

1.A phone device record gets created for an IP phone that is provisioned to be mobile, and the phone gets assigned to a device pool. The phone registers with Cisco CallManager, and an IP address gets assigned as part of the registration process.

2.Cisco CallManager compares the IP address of the device to the subnets that are configured for device mobility in the Device Mobility Info window. The best match uses the largest number of bits in the IP subnet mask (longest match rule). For example, the IP address 9.9.8.2 matches the subnet 9.9.8.0/24 rather than the subnet 9.9.0.0/16.
