In the inventive video telephony method a server of a selected service provider controls transmission of regular video information and voice information between terminals of a caller and a called subscriber during a video telephone call. The server issues a request to the caller to carry out an interactive action during a predetermined time period measured by a timer. If and only if the caller performs the interactive action during the predetermined time period as measured by the timer, additional video information is transmitted to the terminal of the caller from the server and displayed. A fee of the caller may optionally be reduced or increased depending on whether or not the interactive action is performed during the predetermined time period.
