Teams auto answering while in a call?

OK, hope this helps. I tried setting Teams to 'Reject incoming Calls' and disabled connection to my Android. It did not answer the call, but it just sent a message to the caller saying declined and 'still' put existing call on hold ....all automatically, with me touching nothing. I was just ready to buy new headsets, when I decided to call Jabra support. I have the Jabra Evolve 75. They had to step me through some things and 'they' remotely had to reset my headsets. Not only did I need to reset the headset, the problem seemed to lie in the Bluetooth dongle which I believe mine is a 370.  They needed to send a command to reset it also.  This seemed to fix the problem. I need to do one more test with my colleagues, but I believe it worked. Call Jabra Tech Support.
