Abstract:
A method for routing calls between a first and second networks, comprising the steps of:(a) routing calls between the first and second networks across a plurality of routes, each formed by at least one trunk group;(b) recording, for each call across each route, a completion history indicative of whether said call was completed over an egress trunk within an egress trunk group to a far end following trunk seizure;(c) establishing a Completion Rate Factor (CRF) for each route in accordance with the call completion history;(d) establishing a load state for each route based on idle link bandwidth and reservation and traffic level on that route;(e) selecting, among the routes over which future calls may be routed, the route having a CRF representing greatest call completions and lightest load state; and(f) routing future calls on the selected route.
