1:1 calls, user is muted as soon as PSTN ringing starts

I have been having the same issue since last fall with my Bose earbuds but I also have tried some other earbuds that have same issue. While it happens on most outgoing calls, there are some rare occasions that it will work correctly with person not muted. Have not been able to identify the difference and why those calls are not muted. Its so frustrating and I cannot find any settings that let me change it. These earbuds worked correctly prior to last fall. My only speculation was it related to an upgrade in TEAMS. I wish Microsoft would get the issue fixed as its very frustrating when you are calling someone and it mutes them...mine also many times doesn't mute call until right before they answer so its not like you can click it as soon as you dial and it works.
