Rules for Configuring CiscoCallManager Extension Mobility
Logging In and Logging Out
When a user logs in, the current configuration of a device is replaced by a
particular user device profile.
When a user logs out, the current configuration of a device (the user default device
profile) is replaced by the logout profile.
Cisco CallManager Extension Mobility supports only one login at a time on a
device. Subsequent logins will fail.
You cannot log out of a device which does not have anyone logged in.
Configuration Examples
This section describes different scenarios using CiscoCallManager
Extension Mobility:
•Scenario 1: All Users have Cisco CallManager Extension Mobility, page3-3
•Scenario 2: Mixed Configuration, page 3-4
•Scenario 3: Mixed Configuration, page 3-4

Scenario 1: All Users have Cisco CallManager Extension Mobility

In a typical Cisco CallManager Extension Mobility scenario, all employees are
users of Cisco CallManager Extension Mobility. The users are configured to have
a default device profile and they do not control their individual phones. They must
log into a phone before they can use it as th eir extension.
Employees have access to common devices, such as lobby phones, confe rence
room phones, and cubicle phones that are meant to be shared.
When users go to the Cisco Phone User Options web pages to change their
services or speed dials, they can select only their default device profiles from the
“Select a device to configure” drop-down menu. Any changes users make to their
services follows them to any phone they log into.
Note In this scenario, users cannot modify settings for an individual phone.
This is a recommended configuration.
