Claim:
1. A method comprising: creating at least two toll-free call routing tables based on a congestion threshold criterion, wherein the first of the two call routing tables is to be used when toll-free call volumes occurring within a toll-free telecommunications carrier network are below the congestion threshold, and the second of the two call routing tables is to be used when toll-free call volumes occurring within a toll-free telecommunications carrier network are equal to or above the congestion threshold; providing the call routing tables to at least one service control point that is associated with the toll-free telecommunications carrier network; monitoring toll-free call volumes and durations occurring within a toll-free telecommunications carrier network; receiving at least one of a call count datum or call duration datum from the toll-free telecommunications carrier network wherein the call count datum or call duration datum indicates a change in call volumes over the toll-free telecommunications carrier network from below the congestion threshold to above the congestion threshold; and instructing the service control point to switch from using the first call routing table to the second call routing table.
