Abstract:
1. A method for routing a call between an ingress point and an egress point, the call being initiated at the ingress point through entry of an identifier associated with the egress point, the method comprising: receiving the call at a routing component from the ingress point; determining at the routing component if the identifier associated with the egress point is stored in a registry, wherein the egress point is a destination for the call, and wherein storage in the registry indicates registration for direct call routing to the egress point; if the identifier is stored in the registry, determining at the routing component a delivery route for the call, wherein the delivery route comprises (i) a first path to the egress point if the first path is available, wherein the first path is a dedicated connection to the egress point (ii) a second path to the egress point if the first path is unavailable, wherein the second path is a connection to a carrier associated with the egress point, and (iii) a third path to the egress point if the first and second paths are unavailable, wherein the third path is a connection through a public switched telephone network and local exchange carrier associated with the egress point, wherein a path is deemed available based on its ability to carry the call along the path and unavailable based on its inability to carry the call along the path; and transmitting the call to the egress point based upon the determined delivery route.
