What Occurred: Teams Calling intermittently failing with one-way or no-way audio.

What is Affected: Inbound and Outbound Calling through the Teammate Teams Connector

When it began: 11:00am ET, July 23, 2026

Current Status: At 2:36pm ET, Microsoft successfully reverted a network change, along with rerouting traffic, which has restored services on their end. After internal testing, we have confirmed inbound and outbound calling services have been restored.

Next Steps:

• If inbound or outbound calling does not immediately return, please restart the Teams app and reopen. If you continue experiencing call failures, please submit a support ticket to support@oit.co

• With Microsoft being the root cause of the underlying service outage, and not having visibility into the root cause, no major incident report will be provided.
