Outgoing Teams call never stops ringing on the caller's side

[Bradley Fox]

This started with just a couple users a couple days ago now it's spreading.

• Person A Calls Person B via Teams Windows Desktop application.
• Person B Answers.
• Person A still hears ringing on their end.  Ending the call does not stop ringing sound, they have to quit the application.
• Ringing stops on Person B's side after the call is answered.
• If person B calls Person A back the same thing happens to Person B.
• Person A calls Person C and the problem does not exist.

We've tried:

• Using a different device on both ends
• Reimaging the computer on both ends
• Patch Teams (there was no update)
• Moving to a different network (phone hotspot)
• Making sure Teams wasn't installed or logged into on any other devices as these users.
• Looked at policies in Teams Admin center and they match for users with and without the issue.

Having this exact same issue with a few users also.
It seems to be only only internal calls for us, and only a select few users.
Hoping microsoft will acknowledge the issue and release a patch soon as it's very annoying!
