Hi @Kalpesh Patil ,
Does this issue exist all the time for these specific users?
To exclude the client issue, we firstly recommend these users use Teams web client to see if this issue still exists. If it can work normally in Teams web client, please try to sign out Teams client and clear your Teams client cache file to see if it can be fixed.
Besides, you can try to use the Call Quality Dashboard (CQD) to monitor call and meeting quality for your organization. For more details about it, you can refer to:
