Chapter 19 Cisco CallManager Device Mobility

Interactions and Restrictions

Cisco IP Communicator

Interactions and Restrictions

The Device Mobility feature depends on the IP address of the device that registers with Cisco CallManager. If the device is assigned an IP address by using NAT/PAT, the IP address that is provided during registration may not match the actual IP address of the device.

If Device Mobility Mode is set to Default in the IP Phone Configuration window, the Device Mobility Mode service parameter determines whether the device is enabled for the device mobility feature. For information on the service parameters, see the “Service Parameters Configuration” in the

Cisco CallManager Administration Guide. For information on configuring devices, see the “Cisco IP Phone Configuration” in the Cisco CallManager Administration Guide.
