1. A system for routing information comprising:
- a resource manager, the resource manager including a configuration table, the configuration table including at least one group of physical gateway addresses, each of the at least one group of physical gateway addresses having a single and unique logical identifier, the resource manager being coupled to a plurality of gateways;
a proxy coupled to the resource manager;
wherein the resource manager receives a register request message from a selected one of the plurality of gateways, the register request message including a physical address of a selected one of the plurality of gateways, the resource manager responsively determining the logical identifier of the selected one of the plurality of gateways using the physical address, the resource manager sending a register request message including the logical identifier to the proxy; and
wherein subsequent register request messages received from any of the plurality of gateways having the same logical identifier as the selected one of the plurality of gateways are not forwarded to the proxy by the resource manager.
