1. A method for routing telecommunications traffic comprising: in a telecommunication network with a plurality of carrier destinations with a connected network, receiving a first set of call volume data for a plurality of carrier destinations where the first set of call volume is associated with a first price rate loaded into a least cost routing system of the connected network; receiving a second set of call volume data for the plurality of carrier destinations where the second set of call volume data is associated with a second price rate loaded into the least cost routing system of the connected network; upon determining that the second price rate probabilistically caused a change in call volume at the plurality of carrier destinations, classifying an outcome of loading the second price rate into the least cost routing system, the outcome being at least one of a positive outcome associated with an increase in margin between the first price rate and the second price rate and a negative outcome associated with a decrease in margin between the first price rate and the second price rate; and providing for routing traffic using the least cost routing system based on the classified outcome.
