Participant being dropped from Teams Meeting

Participants are increasingly being dropped from meetings. Hard-wired / wireless seems to make no difference. Meetings were set up via Outlook. It is intermittent but once it starts, I am dropped within seconds of connecting and repeatedly. I am connected for 3-5 seconds max.  No error message, just dropped from the meeting.  I've now had numerous  calls that I was never able to join.  The meetings have varied between 3 and 15 participants. Because there is no dial in option enabled for our company, we have no way to join when the program drops us. I would appreciate any suggestions!
