Overview
Centrex is the legacy telephone service provided by our telecommunication carrier’s central office. The carrier owns and manages the equipment and software inside the central office that provides the dial tone, and transmits calls. Communications services provided by Centrex uses older technologies and is in the process of being phased out within the telecommunication industry and on campus. Just as ISC migrated campus from Centrex telephone service to PennNet Phone services, we continue to explore ways to migrate other services still supported by Centrex; such as fax machines and alarm lines for subzero freezers to other technologies which provide those services using our data network. ISC continues to support existing devices that require this type of service as we transition to newer technologies.
Important: Changes to Centrex Fax Services
Please note that we no longer provide new Centrex fax lines. All existing Centrex fax lines will be migrated to PennFlex eFax services. Additional information about PennFlex eFax services is available on the on the PennFlex eFax service page. We will continue to service existing Centrex fax lines on a case-by-case basis.
