Clearing all system initialization values back to their default settings and deleting all user-specific data is intended primarily for repair and for use when the phone is given to a new user. This returns the phone near to its original, out-of-box state. The phone will yet retain the firmware files it has already downloaded.
Note:
Some parameters, such as button clicks, error tones, and personalized ringing, may be set for a specific user via the MENU. These user settings will be restored when you register the user to the phone because those parameters are configured in IP Office. All other settings (for example Contact data, Options settings, and so on.) is cleared from the phone.
