A Home Network telephone system and method are provided for backing up user data. The system comprises at least one endpoint to transceive telephone communications. The endpoints can be devices such as telephones or fax machines, for example. The system also comprises a gateway to service and transceive telephone communication with the endpoints. The gateway has a memory to store a copy of user data associated with each endpoint. The gateway stores user data such as telephone directories, calling line ID (CLID) lists, call-logs, and user preferences for organizing the stored data. The gateway can supply the endpoints with an initial start-up configuration of user data, or resupply an endpoint in response to the endpoint losing the copy of the user data stored in its local memory. Each endpoint receives the user data from the gateway and stores a copy of the user data in a local memory. Conversely, the endpoint has a user interface to generate user data and store the user data in local memory, and the gateway stores a copy of the user data generated by the endpoint in the gateway memory. More specifically, the gateway uses a control channel to receive a copy of the user data from an endpoint, and sends an acknowledgement to the endpoint that the user data has been received. When an endpoint modifies the user data, the control channel is used to send a copy of the modified user data to the gateway. Likewise, the endpoint uses a control channel to request user data from the gateway, in the event of battery failure, for example.
