*> Skype was originally a peer to peer application&
Sure, but Skype adopted a peer-to-peer design back in 2005 or so when expectations were a lot lower - no smartphones, no group calls, no 1080p, no cross-platform, and if it's unreliable or needs some fiddling around to get it to work properly, such is life - because the competition was paying $$$ for an international phone call that wouldn't have any video.
These days if you want to compete with Skype and Google Hangouts and Discord, I expect my regular four-way video call between people using Windows, OS X, Ubuntu and ChromeOS to establish first-time with clear audio and video to all users.
