Probably, since "Skype for Business" is a renamed Microsoft Lync and has basically no technology in common with Skype per se. (Its user experience is also terrible, but differently so.)
An endless source of confusion. What's even more fun is that the two clients almost, but don't really, interoperate, when the stars are in the correct alignment. Peer-to-peer calls and instant messages tend to be okay, but things go sideways when they get stepped into an n-way. It's buckets of fun trying to figure out why some calls get dropped by a Lync-based chat application, only to figure out that the customer was using the wrong client.
