The device profile which is applied after the login process does not get associated with a physical phone. It includes all the properties of a device except the specific ones for that device, such as MAC address or directory URL.

When a device profile has been loaded onto a device, the device adopts the attributes of that device profile. When a user logs in to a phone that is configured for Cisco Extension Mobility and the user has a user device profile that is configured for that phone, the user device profile replaces the existing configuration of the device.

When a user logs out, the logout profile replaces the user device profile and basically the phone can be restricted and to become unusable. Disclaimer: This site is in not affiliated with Cisco Systems, Inc.
