Extension Mobility
CUCM Extension Mobility enables users to log in to Cisco IP phones on which they want to make and receive calls. This capability
ensures that users are not permanently tied to a specific phone, but can instead use any phone from which they can log in. When a
user logs in to a phone, all user profile characteristics are assigned to that phone, including speed dialing, line appearance, calling
privileges, message waiting indicator (MWI), and so on.
Extension Mobility is enabled using XML-based services, relies on the CUCM/Cisco Database Layer Monitor services, and runs as a
Tomcat web service in order to function.
There are a number of steps involved in enabling Extension Mobility:
Step 1.
Activate the Cisco Extension Mobility service in the Cisco CUCM Serviceability tool by going to
Tools, Service
Activation.
Step 2.
Configure CUCM Extension Mobility service parameters, such as Maximum Login Time in CUCM Administration,
by going to
System, Service Parameters
, selecting the server, and then selecting Cisco Extension Mobility from the
Service drop-down list and clicking Save.
Step 3.
Configure Extension Mobility service availability by going to
Device, Device Settings, Phone Services
.
Step 4.
Create a user device profile and subscribe to the Extension Mobility service by going to
Device, Device Settings,
Device Profile
. A user device profile consists of characteristics such as device type, phone button template, softkey
template, directory number, and login user ID. This profile information is used when a user logs in to a phone. Note
that because the profile is specific to a device (phone) type, it will work only when a user logs in to that specific type
of device.
Step 5.
Associate the user with the profile by going to
User Management, End User
.
Step 6.
Subscribe phones to the Extension Mobility service and configure Extension Mobility parameters by navigating to
Device, Phone
.
