Least Cost Routing

This application routes calls according to rules that are held in an internal data store.  Routing may be determined by the operator that hosts a particular non-geograohic number.  Or it may be to minimize transmission cost, by considering the location of the called party, the time of day, day of week, call-minute volume usage, and tariffing rules. The application typically determines the preferred lowest-cost route and also determines a fall-back choice to support route-failure handling when the preferred routing is unavailable.

Operators adopt this service as part of their primary business model, to offer a wholesale, least-cost routing service. ISPs adopt it to offer a value-added telephony service to new and existing clients.
