Abstract:
1. An originating gateway for conveying calls to a data network comprising an interface to receive said calls, a processor to establish routing of said calls based upon information for routing said calls through said data network, the routing information including identification of a terminating gateway of the data network to route the calls to, the routing information being generated remotely during at least one previous call with similar parameters to said calls and a network interface to route said calls based upon said routing information, wherein said calls are routed by: checking local memory to determine if said routing information is sufficient to route said calls over a packet switched data network, if so, routing said calls based upon said routing information over said packet switched data network, and if not, contacting a remote node over said packet switched data network to obtain said routing information; and a cache for storing said routing information, the cache located within the gateway and accessible thereby without requiring that the originating gateway make a connection to any computer external to said originating gateway.
