Definitions for "Least Cost Routing"
A telephone system feature that automatically chooses the "least cost" long distance and local lines to send the call on. The caller typically dials 9 and then the 10-digit telephone number. The call is then routed over the least costly service.
A feature offered by some telephone systems that examines the day, time, and call destination and compares it to a chart of set long-distance carrier rates. As the name implies, the least expensive option is chosen.
