Abstract

A local routing system is provided for selectively routing traffic in a telecommunications network according to a local service provider's preferences. The local service provider provides service for telephone lines acquired from a local exchange carrier. The telecommunications network supports an originator subscribing to the local service provider. The originator initiates a trigger when originating a call to a destination by dialing a number. The local routing system includes a classifier, a detenniner, and a router. The classifier analyzes the dialed number and categorizes the call into one of several predetermined classes of traffic. The determiner determines whether the local service provider has a routing preference for the class of traffic into which the classifier has placed the call. The router routes the traffic to the destination according to the local service provider's routing preference if a routing preference exists for the class of traffic into which the classifier placed the call, and generates billing if appropriate. The predetermined traffic can be operator assistance traffic, directory assistance traffic, and local traffic.
