Abstract
An interexchange carrier (IXC) switch and an associated database route qualified calls dialed to local service provider (LSP) subscribers onto interconnecting facilitiies with local access settlement rates, thereby allowing a local rather than toll cost structure. The IXC switch and associated database operate with existing toll features including those features which translate a private dialed number into a public number. The IXC switch and associated database classify the call into a jurisdictional classification from a customer billing and feature application perspective, and from a routing perspective independent of the customer billing and feature application classification. The jurisdictional classification can include, example, local, toll, interLATA toll or intraLATA toll.
