Centrex provides features similar to those offered by a PBX or a Key Telephone System. With Centrex, a business does not have the expense or inconvenience of on-site switching equipment. Centrex is an excellent alternative for customers who have seasonal business and continuously have to add and subtract line capacity or for customers who can not accurately project growth requirements.
Businesses pay for only for the services they use.
As the needs of the individual telephone users change, a simple service order is all that is required to add or modify features. As new features are developed, they can be made available to the business without the need to purchase new equipment. If your business is spread over a number of different locations and buildings which are all served by the same switching system, Centrex can economically tie all of these locations together with an a single, easy to use communications system. Employees at different locations can use the same features that are available at the main office. All locations can easily communicate with each other.
