A telephone system that can be controlled by graphical user interfaces (GUIs) displayed using a graphical page description language (GPDL), e.g. HTML, on a touch-sensitive display screen provided with the telephone. An application program interface (API) enables a commonly available user interface tool, e.g. Microsoft Front Page, to program any number of telephone functions for display and access via the GUIs on the display screen. Since the GUIs are downloaded from a server connected to the internet, the pages displayed on the display screen can be varied according to personal preference or according to temporal and/or geographical criteria, e.g. advertisements can be sent depending on the time or day, month or year to telephones depending on their location (houses, apartments, hotels).
