Patent ID: 7394897

Claim:
A system for routing a call made from a calling line resold to a carrier, the system comprising: a switch coupled to the resold line, the switch being operative to determine at the switch whether the call is from the resold line and to route the call to a hub without any query to a service control point based on determining the call is from the resold line; the hub having a trigger provisioned thereon to cause the hub to launch a query to the service control point upon receiving the call from the switch wherein the trigger is assigned to the hub on a per-trunk basis so that the hub suspends all calls from a trunk group to the hub prior to launching the query to the service control point the trunk group including the resold line; and the service control point operative to receive the query from the hub and to provide routing instructions to the hub based upon resold line routing information stored in the service control point, the routing information identifying a location specified by the carrier for handling the call, wherein the routing information comprises a single set of line class codes assigned to all resold lines, wherein the line class codes reference a trunk group to the hub, wherein the hub is operative to utilize tabular information in the service control point to make routing decisions based on an area in which a caller making the call from the resold line is located.
