/mcp• The system uses the device profile default for that phone model for phone template and softkey template configuration and, if the phone can support addon modules, for the addon module. • If the phone model supports Cisco IP Phone Services and they are configured, the system copies the services from the user device profile. If the user device profile does not have Cisco IP Phone Services configured, the system uses the Cisco IP Phone Services that are configured in the device profile default for the login device that is accessed during login. If parameters exist for the subscriber service, the system copies the parameters from the device profile default and the parameters may not reflect the correct information. For example, the following scenarios occur when a user who has a user device profile that is configured for Cisco IP Phone Model 7960 logs in to a Cisco IP Phone Model 7905, and the device default profile is loaded on the phone. • The user can access the user's hold audio source, user locale, userid, speed-dials, and directory number configuration. The user cannot access his phone line setting; the system configured the phone line setting from the device profile default that is configured for the Cisco IP Phone 7905. • The user can access the phone template and the softkey template of the Cisco IP Phone 7905. • The user cannot access an addon module because Cisco IP Phone 7905 does not support it. • The user can access Cisco IP Phone Services if they are configured for the Cisco IP Phone 7905, but the parameters from the subscriber services reflect the device profile default, not the parameters that the user chose on the User Options window. Users log out of Cisco Extension Mobility by pressing the Services button and choosing logout. If users do not log out themselves, the system will automatically log them out if you configured the Service Parameters to do so, or the next user of the phone can log out the previous user. After logout, Unified CM sends the logout profile to the phone and restarts the phone.
