Switchboard notified teladmin of issues they were having. Teladmin tested and confirmed.

All Mason Vonage phone users were affected trying to make or receive off campus calling. Users were able to dial internally with 5-diget dialing from the Vonage app, phone and teams integration.

At approximately 12:22 pm ET on Wednesday, October 15, 2025, our internal monitoring systems alerted us that some customers were experiencing an intermittent inability to make or receive calls. Although we operate a redundant environment across two geographically diverse regions, with active failover capabilities in place, during this incident, call failures and service degradation were observed across both sites.

Mitigation actions, including an increase in call capacity and a temporary change to limit repeated call attempts, were implemented. This alleviated network traffic, and service was restored by 5:23 pm ET that same day.

Our engineers are actively working on a comprehensive root cause analysis of this incident. We know how important consistent, reliable service is to your business and to your trust in us, and we are truly sorry for the service interruption that occurred last week. We are taking steps to ensure your experience meets the high standards you deserve and that we hold ourselves to, and we are committed to providing you with an RFO as soon as possible
