So Teams calls of 1-4 people can send traffic direct peer-to-peer if they’re on the same LAN right?
Do all calls of 5+ users stay centrally hosted on the cloud?
These are the kinds of things that MS should document and make easily available for IT and firewall admins. Finding info on Teams ports wasn’t easy in my experience.
Maybe what they are trying to say is that most everyday folks don’t use those terms in any normal conversation. I’ve never used those terms myself and haven’t heard them in any conversation I can recall outside of the Internet.
