Legacy ISDN Centrex Service is End of LIfe

January 10, 2020

As of January 1, 2020, ISDN services is no longer supported by Verizon. 

As of January 2020, Verizon will no longer accept orders for new installations or moves of ISDN service.  HUIT has been working with the schools and departments impacted by this notification to migrate these remaining ISDN phones to VOIP.  In addition to ISDN service, there are some circuits that will also no longer be supported.  We will reach out to the affected schools to work with you to disconnect or migrate these impacted circuits to another solution. 

Analog services are not impacted at this time; however, users should migrate to VOIP as we continue to decommission services associated with the legacy services.  Voice mail for the legacy service is anticipated to be shut down by FY21.
