Enterprise Mobility User (EMU) is a software-only feature that provides the ability to associate the buttons and features of a primary telephone to a telephone of the same type anywhere within your company’s enterprise.
A home station can be visited by another EMU user while the user is registered as an EMU visitor elsewhere. A home station can be used as a visited station while the principal user’s EC500 or other Off-PBX applications are active. And the principal user can activate an Off-PBX application even if their home station is being visited by another EMU user.
Note:
In this document, any telephone that is not the primary telephone is referred to as the visited
telephone and any server that is not the home server of the primary telephone is referred to as the visited server.
