I2-Mitel Voice Services
Wednesday morning May 25th between 6:00AM and 7:00AM, ITS/TNS will perform maintenance work on the core router that will briefly interrupt I2-Mitel voice services.
We ask that you make some inbound and outbound test calls at 7:00AM or your first convenience that morning to verify voice services are functioning.
