  • Telephony - NetPhone
    10/06/2015 - 02:14pm to TBD

    Starting today (10/6) at approximately 2:15 PM, the NetPhone system experienced a call routing issue for inbound calls. The issue was resolved at 2:44 PM. 

    During this time, 10% of NetPhone users may have been unable to receive calls. Any incoming calls to those subscribers were directed to voice mail. Outbound calling for NetPhone users was not affected.

    In addition, NetPhone users that are configured for bridged-line appearance (BLA) might have noticed that their indicator light did not appear. The indicator light should re-appear within an hour.


    For questions or to report on-going issues, please contact the CUIT Service Desk at, or call 212-854-1919.
