An Internet call routing system (200, 250, 300) includes a master controller (220, 264, 314) coupled to a signaling control network, and a call routing element (205, 260, 280, 310) coupled to the master controller and a voice switched network (206, 256, 306). The call routing element receives calls destined for an information service provider (216, 272, 322) from the voice switched network as directed by the master controller. At least one modem bank (208, 262, 284, 312) is coupled to the call routing element and master controller for converting the calls destined for the information service provider from a first format to a second format and then providing the converted calls to a packet data network. Additionally, the modem interface to the packet data network includes a controller (62) coupled to a master controller (220, 264, 314) for receiving control information therefrom. At least one modem (60) receives a call destined for an information service provider from a call routing element and converts the call from an analog format to a digital format. An adaptation unit (66) is coupled to the at least one modem for packing the digital call into a plurality of data packets. A network interface (68) is coupled to the adaptation unit for transporting the data packets to a packet data network.
