Abstract
A method of routing communications traffic includes receiving, at a switch or server of an originating service provider, incoming communications traffic including a terminating number or address. The switch or server is programmed to send a query to a transaction server for a carrier routing. The transaction server determines whether the terminating number or address matches a number in an ENUM database in communication with the transaction server. If a match is found, the carrier associated with the matched number is added to a routing matrix generated by an offline routing matrix generation process to form a supplemental routing matrix. The transaction server then generates using the supplemental routing matrix a list of available route options for delivering the communications traffic to the terminating number or address.
