Abstract
The invention concerns a method and system for interactive communication between at least two users each provided with a telephone set of the switched telephone network, via the Internet. Each telephone set is directly locally connected to an associated interface device. The first user, who initiates the communication, dials on his set the telephone number of the second user indicating to his interface device that he wishes to communicate via the Internet. The interface device of the first user the connects with the interface device of the second user via the Internet, the two telephone sets being rung off. Once the connection has been established via the Internet, each interface device indicates to its associated telephone set, then each of the users picks up his set and communicates interactively with his correspondent via the Internet.
