Possibly Teams video chat which seems to work better more consistently than Zoom or Cisco Webex for small groups. At least in my organization, we've seen a lot of folks move to it in the last two-three weeks.
We now use Teams video chat at work. The results have been mixed. When the number of meeting participants is low (<5) the video seems to work well. Anything above that we start seeing random disconnects. We've had better experiences with Zoom for larger meetings (~25).
At my company we were using Teams' "common" conferences with 230 (1st week) and 250 (2nd week) participants without issues. In this case 248 were listening and 1-2 were talking/videocasting.
Due to there being a 250 participant limit we now switched to live events, and there also has been no issue with that.
