Teams regularly fails at video conferencing. It complains of low network bandwidth at random times, and I check my firewall (OpnSense with fq_codel enabled and reasonable bandwidth limits) to note that it under very light load.

I am not sure if this is a server side thing at Microsoft, or a problem with the application itself. True under Windows, Linux, via local app, and via the web app.

For larger meetings (> 50 people), we use zoom. Unlike teams, zoom generally just works. Quite well in fact.

Teams is simply crap software, forced upon us. If we could jettison that and Outlook, I would be grateful. Though our IT looks at us in an unblinking stare, if we ask them to allow us to use any of the better clients on mobile, laptop, desktop, windows or linux. Its almost as if our third eye in the middle of our forehead opened up.
