A system for enabling Data Network Telephony (DNT) communication through a WEB page includes a Web server hosting an interactive WEB page and having an Internet port, a link in the WEB page adapted for launching a DNT-capable telephone module, and a DNT-capable telephone module associated with the link. In this system, upon selection of the link by a person accessing the WEB page over the Internet using a computer platform, an instance of the IP telephone module is downloaded to computer platform, and an IP call is launched to an IP address pre-stored and associated with the link. The DNT network may be the Internet. In a preferred embodiment the system first investigates the computer platform for hardware and software characteristics, and attaches the determined characteristics to the instance of the IP telephone module to be downloaded. The downloaded module then self-launches and configures, and then launches the associated call. In some embodiments the module disappears after a single call, and thus serves as an instant enabler for IP telephony.
