Implementing Device Mobility in Cisco Unified Communications Manager

Chapter Description

This chapter describes Device Mobility, a new feature of CUCM allows CUCM endpoints to be dynamically reconfigured based on their actual location as determined by the IP address that is used by the device.

Summary

The following key points were discussed in this chapter:

  • Issues with roaming devices include inappropriate region, location, time zone, and SRST reference configuration. PSTN calls use the home gateway instead of the local gateway at the roaming site.
  • Device Mobility allows roaming devices to be identified by their IP addresses. It also allows configuration settings to be applied that are suitable for the device's current physical location.
  • Device Mobility configuration elements are Device Mobility Groups, physical locations, device pools, and DMIs.
  • Roaming-sensitive settings are applied to devices that roam between physical locations. In addition, Device Mobility-related settings are applied to devices that roam within the same Device Mobility Group.
  • After you configure Device Mobility Groups, physical locations, device pools, and DMIs, you need to enable Device Mobility either clusterwide as a service parameter or individually per phone.
