1. A method implemented by a computing device, the method comprising: receiving, by the computing device, network information, least cost route (LCR) forecast information, network administrator inputs, and looping exceptions; receiving, by the computing device, a call, from an originating location, to a terminating location; determining, by the computing device, a LCR for the call based on the network information, the LCR forecast information, the network administrator inputs, and the looping exceptions; generating, by the computing device, routing instructions for the determined LCR; and providing, by the computing device, the routing instructions to one or more network elements associated with the determined LCR.
