<p>A communication apparatus allows an efficient transmission/reception of a document for a sender and a receiver at their respective desired time and location. When a first user transmits a document using a facsimile machine (transmitting device) managed by a server, first, an account of the transmitting device is registered on the server. In such a state, when the first user inputs an account of a second user as a destination into the transmitting device, the transmitting device inquires the server of a registration status of the second user. The server checks the registration status of the account of the second user. When the account of the second user is registered on any facsimile machine (receiving device), the server notifies the transmitting device that the account of the second user is registered on the receiving device. Then, the transmitting device transmits a connection demand to the receiving device to transmit data of the document.</p> |
