You then responded to this comment by just matter-of-factly asserting that you had the list of missing alternatives... but, really, you are simply hijacking the thread to point out that alternatives exist "which allows all the data to remain on your own servers"; but, you provide no evidence or argument to address whether these products are actually "comparable" (to the point where it just feels like you didn't even understand the point being made) in a way that, say, Google Hangouts--which is the product Google created WebRTC for!--isn't.
