System and method for routing communications between packet networks based on intercarrier agreements

摘要

A system and method for communicating data packets over packet network owned by different communications carriers. Rate information may be stored in a first packet network for communicating data packets over at least two other packet networks. A determination over which of the at least two other packet networks to communicate data packets based on a lowest billing rate for communicating the data packets may be made. The data packets may be communicated over a packet network determined to have the lowest billing rate for communicating the data packets.
