In one embodiment, a method for enhanced extension mobility includes accessing user input indicating either a desire of a user to logon at an endpoint in a private mode according to which the endpoint supports only an extension of the user or a desire of the user to logon at the endpoint in a shared mode according to which the endpoint concurrently supports an extension of the user and one or more other extensions of one or more other users. The method includes configuring the endpoint to support only an extension of the user if the user input indicates a desire of the user to logon at the endpoint in a private mode according to which the endpoint supports only an extension of the user. The method includes configuring the endpoint to concurrently support an extension of the user and one or more other extensions of one or more other users if the user input indicates a desire of the user to logon at the endpoint in a shared mode according to which the endpoint concurrently supports an extension of the user and one or more other extensions of one or more other users.
