Abstract: Terminals having analog/digital telephone functions as well as data exchange functions are used by users who are of lower skill level than the average user of a personal computer. Therefore, the userfriendliness of a system comprising such a terminal should be as high as possible, which can be realized by providing the system with coupling means for coupling a server-memory of a server provider and a network-memory of a telephone network for storing information with respect to messages stored in one of said memories into the other memory. Then the user only has to contact either the server or the network to find out if there are any messages for him. Such a system is very userfriendly.
