System Programming
Least Cost Routing (LCR) Programs
Least Cost Routing (LCR) is a system programmable feature that automatically selects the least expensive route available at the time a long distance call is made.
It is not necessary to dial the access code of the least expensive carrier. You must assign the programs on the next page to activate the LCR feature.
The following chart shows the procedure of LCR feature.
