Incident information
Title: Incoming calls can't be answered in Microsoft Teams intermittently
ID: TM212147
Status
Service Restored
Details
Title: Incoming calls can't be answered in Microsoft Teams intermittently
User Impact: Incoming calls to users may have been intermittently dropped upon answering.
Final status: We've confirmed that the new Teams iOS client build 2.0.010 which contains the fix for the problem is now available for download in the iOS App Store. As the auto-update feature for the app remains disabled at this time, we encourage affected users to manually update to the latest version of the Teams iOS client to resolve the problem.
Scope of impact: Impact was intermittent and specific to users who were signed in to the Teams iOS app alongside any other version of the Teams client with the same account.
Start time: Tuesday, May 5, 2020, at 5:30 AM UTC
End time: Friday, May 8, 2020, at 4:00 AM UTC
Root cause: The Teams iOS client build 2.0.9 contained an error that would intermittently cause incoming calls to drop upon answering.
Next steps:
- We're working to identify additional testing methodologies to better ensure the efficacy of our iOS client builds.
We'll publish a post-incident report within five business days.
Thank you,
The Microsoft team
