Abstract
A least cost routing system comprises at least one telephone dialing unit, at least one least cost router and a database updating unit. The telephone dialing unit dials a telephone number to place a telephone call. Each least cost router has a corresponding routing database of tariffs of telephone service providers and determines, from information in its corresponding routing database, which telephone service provider or providers to utilize to execute the telephone call. The database updating unit electronically updates tariff information into each of the routing databases shortly after updated tariff information is entered therein.
