Chapter 3 Configuring Cisco CallManager Extension Mobility
Rules for Configuring Cisco CallManager Extension Mobility
Configuration Rules
To avoid problems deploying Cisco CallManager Extension Mobility, be sure to
follow these configuration rules:
• If you want to enable all phones within your Cisco CallManager cluster for
Cisco CallManger Extension Mobility, you must not allow the users to
control these devices. That is, when a user goes to the Cisco IP Phone User
Options web page to change his services, he can only select “Default Device
Profile” from the “Select a device to configure” drop-down list. He cannot
modify the settings for an individual phone.
• If there is a device which a particular user controls, for example, his office
phone, you must not allow anyone else to log into that device.
Note The administrator can change the services for a phone in the
Cisco CallManager Administration page. After making the changes, if he
updates on the main page (not the pop up menu) the administrator is prompted
to reset the phone for the changes to take affect. Then, the new snapshot is
stored as the logout profile.
Note It is recommended that each user of Cisco CallManager Extension Mobility
log into his phone at the beginning of the work day. This ensures that his
default device profile is loaded on his phone. He can make changes to this
profile and it will follow him where he logs in.
