The Cisco Extension Mobility feature, sometimes referred to as hoteling, allows a user to temporarily configure another IP telephone as their own. The user must log into that IP telephone with a username and PIN. Once logged in, the phone has the user's profile information, including their extension number (the reason for calling it ‘extension mobility’), dial permissions and other feature settings (e.g. call forwards).

Extension mobility is often by people who frequently travel between different company locations. They can use any fixed-line phone in the company as if it is their own telephone by logging in. Extension Mobility is also useful in situations where people don’t have a dedicated desk of their own. In a flex-office where people just enter and pick a desk, they can easily register on that desktop phone and use it as theirs. It is convenient since people can use their own features, but also it makes people reachable. The number of missed calls will be minimal.
