In Blocked or Limited mode, you must configure phone keys in Avaya Aura® System Manager (SMGR) and download changes to the phone. The phone forces all the call appearances, bridged appearances, feature buttons, and autodial buttons to appear in the same location. The user cannot delete or move them. For the feature buttons and autodials, only buttons that you mark as favorites are displayed on the main phone screen. You can control where the buttons appear on the phone and prevent users from moving them.
