A system and method for routing calls between a circuit-switched network, such as the Public Switched Telephone Network and a packet network, such as the Internet, is disclosed. Signaling System 7 messages are received from the circuit-switched network and are converted to packet-based protocol in an inter-network gateway. The gateway communicates with the Internet and with other devices, such as a modem pool or Remote Access Server, via an Internet Protocol network. The gateway identifies Internet access calls, Voice over IP calls, or other calls directed to a packet network, and routes the calls to the appropriate modem pool, Remote Access Server or media gateway. |
