Introduction
This document explains the Device mobility feature on Cisco Unified Communications Manager.
Device mobility, which allows Cisco Unified Communications Manager to determine whether the phone is at its home location or at a roaming location. Cisco Unified Communications Manager uses the device IPsubnets to determine the exact location of the phone. By enabling device mobility within a cluster, mobile users can roam from one site to another and acquire the site-specific settings. Cisco Unified Communications Manager then uses these dynamically allocated settings for call routing, codec section, media resource selection, and so forth.
Device mobility allows CUCM to apply site-specific configuration to roaming devices
such as Jabber clients. This helps a roaming device uses local-site gateways for PSTN (where applicable) or is restricted to VoIP-only access.
Configuration
Step 1 Enable the device mobility mode in the Service Parameter Configuration or Phone Configuration window. (System > Service Parameters (choose Cisco CallManager service) or Device > Phone)
Step 2 Configure physical locations. (System > Physical Location)
Step 3 Configure device mobility groups. (System > Device Mobility > Device Mobility Groups)
Step 4 Configure subnets and assign one or more device pools to a subnet in the Device Mobility Info Configuration window. (System > Device Mobility > Device Mobility Info)
Step 5 In the Device Pool Configuration window, update your device pools for device mobility settings, if you have not already done so. (System > Device Pool)
Step 6 If you have not already done so, update your dial plans for device mobility; for example, update calling search spaces, AAR group settings, and so on. (Call Routing > ...)
