<p>A process for routing a call between an ingress point and an egress point is based on an identifier, such as a number, assigned to the egress point and a registry in which identifiers are stored. A network routing component receives the call from the ingress point and consults the registry to determine if an entry with the identifier of the egress point being called is stored therein. If a corresponding entry exists, a delivery route for routing the call to the egress point is determined. The delivery route may be a first path to the egress point if available. If the first path is not available, one or more secondary paths are determined, where one is utilized for sending the call to the egress point. The utilized secondary path may be the most optimal path for the call based upon established preferences and call features.</p> |
