When authorized, a user of a computing device, such as a smart phone, may place a communication using an originating number that is different from the number assigned to the computing device. An IMS application server that handles requests for the computing device associated with the originating number is notified when the telephone number assigned to the computing device is used by a different computing device. The notification to the IMS application server might include, but is not limited to device information, location information, and the like. After being notified of the communications terminated by other computing devices that are associated with the device number, accurate call records may be provided regarding the communications involving the originating number.
