Abstract: A method is described for routing calls outside of a carriers network based on characteristics of the call, the attributes of the caller, the status of subscriber-provided resource, and the status of network telephone provided facilities. Information about the call and the caller's identification is sent from the public switched telephone network to a subscriber call routing processor. The carrier is directed by the routing processor to route the call to the subscriber's resource best able to handle the call. Information about the call and the business relationship the caller has with the subscriber is used by the routing processor to determine which type of resource is needed to handle the call. The routing processor then chooses the particular resource of that type to which the call is to be routed based on the current status of the resource, the status of the network-provided facilities, and the criteria established by the subscriber for selecting between alternative resources.

Abstract: A deterministic call routing system tests the allocation of an incoming call to each of X locations and selects the appropriate location. Particularly, it simulates allocation of the call to the first resource and calculates the contribution of this allocation to the deviation of a distance expression from zero. It then simulates allocation of the call to the second resource and calculates the contribution of this allocation to the deviation of the distance expression from zero. This process continues by simulating the allocation of the calls to each of the remaining X resources in turn. The algorithm then selects the location for which the deviation of the distance expression from zero will be a minimum, and actually allocates the call to that location. A call counter for that location is then incremented by one, and the allocation is then ready to allocate the next call.
