Least-cost routing is the process of selecting a telecoms carrier on a trunk provided by another telecoms carrier. It is usually a four-digit code dialled before a number that instructs the telephone exchange to pass the call to another carrier, rather than carry it itself.
For example, you may have if your lines are supplied by British Telecom, but you may want to choose use a different carrier because their prices are cheaper. If you don't have a direct connection to the other carrier, you need to for certain calls, you can inform the British Telecom exchange not to try to connect this call those calls directly, but to route it them to the other carrier network for them to connect the call. Although you are using a BT line from your premises to the exchange, the lines of the other carrier 's lines will be used from the exchange to the call's destination. Each carrier has its own access code which, when prepended to the dialled number, the BT line will recognise to which carrier to pass the call has to be passed over.
A list of such access codes , - along with the tariff table you wish to use to cost calls routed by this particular code , - is contained in the LCR.CFGcfg file, located within the main installation folder
