Abstract: Because of technological and regulatory changes, telecommunication service is becoming more of a commodity, with competition between service providers for traffic. The herein disclosed invention stimulates this competition and facilitates a service provider's and a consumer's ability to make economic choices between competing telecommunication carriers. In this method and system, telecommunication switches route calls in accordance with economic incentives (e.g., least cost routing) resulting from a bidding process between participating telecommunication carriers (Carriers), administered by a bidding service provider through operation of a central processor, a computer referred to as a bidding moderator (Moderator). Some of these switches may be provisioned to treat every call attempt presented to them as a call attempt to be routed to the low-bidding Carrier.
