Hi, Difficult to advice a solution for this problem since we don't have much information about any particularities on your Teams setup that migh be causing this problem. For instance, It migh be caused by bad Internet connection either in your side or in your caller side
If it's working on other devices, that implies permissions and general config is OK. Presence status on your PC? Try changing speaker/microphone devices e.g. from headset to inbuilt? Tried in the Windows Sandbox / HyperV (be sure to enable speaker/microphone mapping)? Tired running Sysinternals Process Monitor to see what happens at the time of disconnection? Same on Teams Web?
