System and method for routing calls from a voice network to data communications network

摘要

An Internet call routing node includes an Internet call routing database for storing rounting numbers for routing calls directed to an Internet service provider to a remote network access server. An Internet call routing process determines whether a call signaling message relates to a call directed to the Internet service provider. In response to determining that the call is directed to an Internet service provider, the Internet call routing process performs a lookup in the Internet call routing database to determine the routing number for routing the call to the remote network access server.
