Abstract

Method and network for routing a communication through an alternate carrier. The network routes a communication based on a dedicated identifier through a plurality of interexchange carriers upon input of the dedicated identifier and a request code, and has a node configured to request carrier data in response to entry of the dedicated identifier, and a controller operably connected to the node, the controller configured to set as a primary carrier, in response to a first condition of the request code, a carrier of a sequence of carriers assigned to the node, and in response to a second condition of the request code, setting an alternate carrier to a highest remaining ranked carrier of the sequence of carriers.
