Resolved - Microsoft has stated that this issue is now resolved. If there were any forwards in place we will get those removed. Here is the update provided by Microsoft on their ticket TM394507.

Title: Users' calls to auto attendants may fail to transfer after selecting an option
ID: TM394507

Status: Service Restored

Restored Services: Microsoft Teams

Details:
Title: Users' calls to auto attendants may fail to transfer after selecting an option
User Impact: Users' calls to auto attendants may have failed to transfer after selecting an option.
More info: After users selected an option from the auto attendant menu, there was no audio for up to three minutes, the call stated that it couldn't connect, and then the call disconnected.
Final status: We've determined that a recent update to service components that facilitate auto attendant functionality contained a regression. We've reverted the update and confirmed via telemetry that the impact is resolved.
Scope of impact: This issue could have potentially affected any users' calls to an auto attendant when transferring their call after selecting an option.

Start time: Tuesday, June 21, 2022, at 1:30 PM MT

End time: Tuesday, June 21, 2022, at 4:20 PM MT

Root cause: A recent update to service components that facilitate auto attendant functionality contained a regression.
Next steps:
- To help prevent similar impact in the future, we're further reviewing the underlying cause of the regression and how we can improve our validation procedures to catch such issues before deployment.
This is the final update for the event.

CallTower will be closing this master case and all associated cases.
