Central office exchange service (or Centrex) is a service provided by local telephone companies in which business users can utilize the telephone facilities at the telephone company's central office, eliminating the need for them to purchase and maintain their own private branch exchange (PBX) equipment.

PBXs are private telephone systems owned and operated by individual businesses.
