<p>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 also receives signaling from the Internet or other packet based networks. A signaling guardian application is located at the SS7/IP border and protects the signaling networks from harmful and/or suspicious signaling from the other network.</p> |
