Troubleshooting for Connection Issues and Dropped Calls

Understanding the Basics

Wired ethernet provides the most reliable service.

Wi-Fi and cell phone signal (if using Teams on a mobile device) may be less reliable in some campus locations.

Other Helpful Tips about Mobile Devices (if applicable)

  • Microsoft Teams apps, including Teams Voice, depend on the Internet.  In the event of an Internet outage, Microsoft Teams devices connected to campus wired/wi-fi networks will be unavailable.  In this rare case, having the Teams app on a mobile device will ensure phone calls can be placed or received. This is optional, unless otherwise arranged with your department.
