Abstract: In communications, there exist various communication ways with different control (WWW, WAP, email, SMS . . . ). Messages are written, sent and received using different user interfaces. With present communication ways it is difficult to connect them mutually and to redirect one communication way into another. Also simple person to person communication tool is missing.

Abstract: A communication method of sending and receiving messages via n communication lines. For each sending line there is corresponding receiving line with the same identification (e.g. mobile phone number). The first message to a receiver is sent via the first communication line, the second message to a receiver is sent via the second communication line, . . . the n-th message to this receiver is sent via the n-th communication line. When a reply from a receiver comes back via the i-th communication line, it is assigned to the i-th message sent. For each sent message the communication system remembers the sender, so that the reply can be delivered to this sender.
