Abstract
A method of providing prioritized call route lists to network elements of communication service carriers. The method comprises building prioritized route lists by a centralized routing function (CRF) platform by processing prioritized route list transactions built by a route generation application based on key performance indicators, receiving a request for a prioritized route list by the CRF platform from a session border controller (SBC) controlled by the first communication service carrier, where the request comprises an identity of a second communication service carrier and a destination telephone number, determining a subscriber service level associated with the second communication service carrier by the CRF platform, based on the determined subscriber service level, looking up a prioritized route list by the CRF platform based on the destination telephone number, and sending the looked up prioritized route list by the CRF platform to the SBC.
