HCIS staff will be performing planned analog gateway maintenance on all analog gateways serving the University of Iowa. Each gateway will be migrated individually, with an expected downtime of approximately 5 minutes per gateway. These cutovers will occur sequentially on  Monday December 22nd between 5:00 PM and 6:00 PM, resulting in temporary dial tone interruptions during this window.

What to Expect: During the migration, dial tone service will be temporarily unavailable for the following systems:

• Elevator phones
• Fire alarm panels
• Area of Refuge communication systems
• Classroom phones
