I worked somewhere that used this software that had this exact feature. This was pre pandemic and they had two offices and a few remote employees. You could barge in and open up a video chat instantly if you really wanted but that was considered poor form. The more common thing was the "knock" button that would play a tone and ask if you were available for the pop in, which would start instantly when you accepted. It worked surprisingly well, although I did some consulting for them years later and they had moved to slack/google meets. https://www.sococo.com/ https://www.sococo.com/
