Right now, we are evaluating Zoom and MS Teams. Zoom simply does multiple incoming video calls FAR better than MS Teams. Seems like MS is just not committed to MS Teams. I frequently have 4-5 people in an MS Teams meeting and at least one always has a conference room with multiple people. MS Teams resizes the feeds to people get cut off or the aspect ratio is weird. Why can't MS just give us the ability to just say "SHOW ME THE ORIGINAL ASPECT RATIO AND ENTIRE FEED FOR EVERY USER" instead of assuming we want it to try to "intelligently" focus on who's talking. This is terrible. Zoom is far superior.
