GLOSSARY

Cloud Communications Terminology

Least Cost Routing | LCR

Least Cost Routing, or LCR, uses machine learning and rate tables to ensure that voice calls take the lowest cost route from initiation to destination. Rate tables are based on the last two numbers of the phone number, and they also take into account where the call originates and where the destination number is located. Because it is highly automated, this process takes less than a second, so it doesn’t slow calls down.

Nearly all major carriers and some enterprise calling solutions use LCR technology to route calls effectively and efficiently. Similarly, Intelligent Call Routing utilizes least cost routing technology but also factors in call quality and deliverability.
