Device Mobility Feature on CUCM 10.x

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 > ...)

Nice Document Lavanya!

 

Can you tell what is the difference between Extension Mobility and Device Mobility?

 

Regards,

Saravana. M.

Hi,  Thanks Saravana.

CUCM offers different types of Mobilty features

1. Device Mobility
2. Extension mobility
3. Cisco unified mobility

Extension Mobility is a feature that allows users to roam between phones, all the while taking their numbers and specific device settings with them. Users can move between floors, sites and geographic locations and utilize only cisco unified IP Phones as long as the user roams. Extension mobility is extended only to cisco unified IP Phones. Whereas,

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. You can configure 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 IP subnets to determine the exact location of the phone.
