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.
