Routing Tables are a great alternative to smart routers to route calls to different endpoints when there are an abundance of tracking numbers involved. The table consists of one value or key to determine where to route a call. Unlike the smart router there is no extensive logic, only a one to one match between a value (key) and a route (queue, receiving number, agent, etc.). The value is a field within CTM and can be one of a variety of different fields such as a tracking number, custom field saved to the tracking number, city or state.
