20. Mobile Voice Access Configuration Procedure
1. Activate Cisco Unified Mobile Voice Access
Service.
2. Configure service parameters:
3. Enable MVA per end user.
4. Configure MVA media resource.
5. Configure MVA VoiceXML application at Cisco
IOS gateway.
27. Device Mobility Characteristics
Device Mobility can be used in multisite environments with
centralized call processing.
Device Mobility allows users to roam between sites with their
Cisco IP phones (typically Cisco IP Communicator or Cisco
Unified Wireless Phones).
IP phones are assigned with a location-specific IP address by
DHCP.
Cisco Unified Communications Manager determines the physical
location of the IP phone based on the IP address used by the IP
phone.
Based on the physical location of the IP phone, the appropriate
device configuration is applied.
28. Dynamic Phone Configuration Parameters
Roaming-Sensitive Settings:
– Local Route Group
– Date/Time Group
– Region
– SRST Reference
– Media Resource Group List
– Location
– Network Locale
– Physical Locations
– Device Mobility Group
Device Mobility-Related Settings:
– Device Mobility CSS
– AAR CSS
– AAR Group
– Calling Party Transformation CSS
29. Configuration Element Functions

Defines a set of common characteristics for devices. The device
Device Pool (DP) pool contains only device- and location-related information. One
device pool has to be assigned to each device.
Specifies an IP subnet and associates it with one or more device
Device Mobility Info (DMI) pools. Multiple Device Mobility Infos can be associated with one
device pool.
The physical location is a tag assigned to one or more device pools.
Physical Location (PL) It is used to identify whether a device is roaming within a physical
location or between physical locations.
The Device Mobility Group is a tag assigned to one or more device
Device Mobility Group
pools. It is used to identify whether a device is roaming within a
(DMG)
Device Mobility Group or between Device Mobility Groups.

31. Device Mobility and Calling Search Spaces
Line CSS is never modified by Device Mobility.
Device CSS is modified only when roaming between physical locations
and within the same Device Mobility Group.
– Operation when using the line/device CSS approach (recommended
for CoS implementation):
Line CSS is not modified—CoS settings are kept.
Device CSS is modified—Allows local gateway selection by
applying CSS of roaming device pool.
– When using the traditional CSS approach (only one CSS at phone),
use the device CSS instead of the line CSS in order to allow the CSS
to be modified by Device Mobility.
AAR CSS is configurable only at the device and therefore is always
correctly modified when roaming between physical locations and
within the same Device Mobility Group.
35. Device Mobility Configuration Steps
1. Configure Physical Location.
2. Configure Device Mobility Group.
3. Configure Device Pool.
4. Configure Device Mobility Info.
5. Set the Device Mobility mode using:
a)A Cisco CallManager service parameter to set
the default for all phones
b)The Phone Configuration window for individual
configuration per phone

Extensions are traditionally bound to constant devices.
User gets wrong extension on that phone.
User gets wrong calling privileges.
User does not have speed dials available.
User has wrong services assigned.
Message Waiting Indicator (MWI) status will not work
with different extension.
45. Extension Mobility Login Process
1. User presses the Services button on
an IP phone and selects the Cisco
Extension Mobility service.

47. Extension Mobility and Calling Search Spaces
Device CSS is never modified by Extension Mobility.
Line CSS is always modified by Extension Mobility:
– Operation when using the line/device CSS approach (recommended
for class of service [CoS] implementation):
Line CSS of user device profile is applied—CoS settings of the
user are enforced.
Device CSS is not modified—Allows local gateway selection
depending on used device (at any location).
When using the traditional CSS approach (only one CSS at phone),
the same CSS (either device or line) is used all the time, which causes
problems in multisite environments with different CoS for users.
AAR CSS is configurable only at the device and is never updated by
Extension Mobility – allows local gateway to be used for AAR calls.
48. Extension Mobility Configuration Steps
1. Activate the Cisco Extension Mobility service.
2. Set Cisco Extension Mobility service parameters.
3. Add the Cisco Extension Mobility phone service.
4. Create default device profiles for all phone models
used.
5. Create device profiles and subscribe them to the
Cisco Extension Mobility phone service.
6. Create end users and associate them with device
profiles.
7. Enable Extension Mobility for phones and
subscribe phones to the Cisco Extension Mobility
service.
