LEAST COST ROUTING
Least Cost Routing (LCR) automatically selects a low-cost phone line based on the number dialed.
Least Cost Routing (LCR) looks at the dial string that a person dials from their station, prefixes the
number with the long distance carrier access code (if defined), and then routes that call to a
specified Line Pool.
Least Cost Routing on the VS1 System does not guarantee the least expensive method of call
routing. Cost savings are incurred when low rate long distance carriers are listed in the Least Cost
Routing window. As long distance carrier rates fluctuate, the Least Cost Routing window must be
maintained to reflect the current low-cost carrier for a given area code.
