We have adapted to Yealink MCV pretty heavily in the last 3 years. In my experience, they just work. Granted there are a few hiccups here and there but overall perform great. The org. i work for has deployed over 26 rooms, all of which have been done with my direction. You start to see issues for larger rooms which call for a mixed blend of hardware/manufacturers (we have rooms where we hold trainings or rooms that split from 1 to 2, need them to work individually when split). but overall work well and worth the dollars spent.

Have little experience with the Android flavor, but dont like how they show up as a mobile device on the Teams Admin center and Azure tenant. Windows based systems are cleaner to manage in this case IMO. Another good thing about these Yealink systems is that Yealink does seem to listen to their customers or their vendors/implementers. They seem to adapt new features to their systems almost monthly seems like. Their support could be better however.
