BellSouth® Centrex is a voice communications system that uses the power of the BellSouth central office to provide internal and external communication service to businesses.

There is no expensive equipment to outgrow as BellSouth® Centrex service is flexible in size and has an array of over 100 features that customers can select to fulfill their business needs. Businesses can change in size, enlarge or scale down, without having to replace their communications system. All upgrades and changes are done at the central office. Whether a business has two lines or 100, every user in the business has a unique direct telephone number. Each BellSouth central office is monitored, maintained and backed up 24 hours a day.

Reliability and redundancy are also built into the systems so that businesses have the continuity protection they need. BellSouth® Centrex service is the edge businesses need in connecting to the future. And now with BellSouth Centrex Control, businesses gain the ability to manage their own telecommunications service. The new Graphical User Interface (GUI) is designed to provide Centrex management functionality that is efficient, easy to learn, and easy to use.
