.. _extension-mobility-intro: Extension Mobility ------------------ .. _20.1.1|VOSS-687|EKB-4500: Extension Mobility (EM) profiles, often referred to as roaming profiles, enable a user to log onto a phone in another location and the phone automatically adopts the profile for that user. An EM profile is required for users who move between locations on a regular basis, or for users in an organization or location, who have been assigned an extension mobility profile rather than a permanent phone. VOSS-4-UC provides three ways to create, manage and associate extension mobility profiles: * when adding a subcriber using the add Subscriber workflow - see :ref:`add_subscribers` (**Extension Mobility** tab). * when adding a subscriber using Quick Add Subsciber - see under Quick Add Subscriber: Overview * when adding a standalone Extension Mobility - see :ref:`standalone-extension-mobility`.
