Centrex, Retirement

What departments can expect in regards to Centrex retirement

Centrex phone numbers can no longer be reused for Lync or RightFax. 

What we are doing
  1. Analog Equipment:  We are in the process of  implementing an alternative analog connectivity service. Except those Centrex lines used for faxing, all remaining Centrex lines will be transitioned. Customers will be able to keep their telephone numbers.

  2. Faxing with Sensitive Data: We are in the process of implementing an alternative fax service.  All remaining Centrex lines flagged as being used for sensitive data will be transitioned. Customers will be able to keep their telephone numbers.

  3. Replacing Point of Sale Devices: We are working with OBFS, which is in process of replacing point of sale devices that utilize the campus network.  Once that process is completed, phone lines will not be needed for this service.  OBFS will notify us of completion so that we can disconnect the unneeded Centrex lines.

 The original timeline for retiring the Centrex service is June 30, 2017.  Until we implement alternative services, however, Centrex lines used for the above purposes will not be transitioned and will remain functional. 


Since new service offerings will likely not be available before June 30, 2017, we will use the state-level Centrex contract for a temporary period until we have implemented suitable alternative services.  The state is also retiring Centrex, but their contract expires after the University contract. We do not expect that rates will change for campus departments.
