Abstract: A method and system for routing and transmitting data packets over a bypass circuit-switched telephone network from a source computer coupled to a packet-switched computer network via a source router and a destination computer coupled to said packet-switched computer network via a destination router. The source computer designates data packets to be transmitted over the bypass circuit-switched telephone network. These data packets are detected by the source router which establishes a connection to the destination router via the bypass circuit-switched telephone network. The source router then transmits the data packets to the destination router via the bypass circuit-switched telephone network. The destination router then transmits the data packets to the destination computer.
