  • Patent number: 8014292
    Abstract: Methods and computer-readable media are provided to select the optimal route for communicating a signaling message in a telecommunications networking environment. The method includes receiving a signaling message at a sending proxy that is responsible for sending the signaling message to its destination. To determine the best route, the sending proxy inspect its dynamic routing table to identify one or more potential routes that can be used to communicate the signaling message to its destination. The optimal route is determined by a numeric value, which may be based on one or more of a cost, the relationship between service providers, quality, or the like. Once the optimal route is determined, it is communicated from the sending proxy to the receiving proxy, often through one or more intermediary proxies.
