Microsoft have provided an update confirming that they now made changes which have resolved the Teams service disruption. Microsoft update as follows:

Current Microsoft status: Our investigation identified that a portion of service infrastructure responsible for PSTN calling was performing below acceptable thresholds. We've redirected traffic to a healthier portion of infrastructure while we continue to identify what caused this to under perform. We'll monitor the service for recovery and provide progress updates.


We have detected a Microsoft Teams outage this morning which is causing inbound and outbound Teams calls to fail.
