Hi
@rdb-dbaOk, let's start with asking some broad spectrum questions
1.) Is it a Teams Meeting or 1:1 call, or both?
2.) Is it VOIP Call, PSTN Call, or both?
3.) Is it an external mic, or built in? If external what brand/model is it?
4.) If it is external mic have you tried disconnecting/reconnecting, latest drivers
5.) Does it occur on a test call (via settings)?
6.) Is Teams Client updated to latest version?
7.) Have you tried uninstalling/reinstalling Teams?
8.) What if someone hard mutes you in a meeting?
Let me know
Best, Chris
