Skype consumer (skype.com) has nothing to do with Teams, Skype for Business, Lync, or Office Communicator. People are getting this very confused in this thread.

They shared a name for a handful of years. That's it.

Teams does not share components with Skype consumer; at most they both used SILK, but Teams moved to Satin in 2021. It does use [backend] components from SfB as it is the evolution of that service.

Does it? Isn't it just a WebRTC thing?
