Abstract
A method and system is provided wherein routing information is obtained from previously cached information or from a gatekeeper. An originating gateway in a network receives a request for a connection and determines whether pertinent routing information is cached. If available, the cached routing is used to attempt to establish a connection. If no previously established routing is available, the originating gateway requests preferred routing from a gatekeeper, including prioritized selections of terminating gateways through which to make a connection to a designated call recipient. In a further embodiment of the invention, a process is provided to respond to a complaint regarding the quality of service. The system determines whether the reported problem is general or isolated; if it is general, alternate call routing is devised.
