What Does Least Cost Routing (LCR) Mean?
In telecommunications, least cost routing (LCR) is the idea of choosing the path with the least distance for the data trajectory. This can help with the cost of telephone calls. Engineers have to analyze, select and direct the path of outbound and inbound calls.
Techopedia Explains Least Cost Routing (LCR)
Typically, least cost routing involves creating what is known as a “routing table” matching telephone dial codes to destination networks. This can be done manually or with the use of software. One of the challenges with least cost routing involves the size of the call routing table, where new methodology has evolved the use of LCR protocols.
