The Skype communications platform officially became part of Microsoft Office today At the Convergence conference in Atlanta, the company announced the end of the Lync era with the launch of the Skype for Business technical preview.
It is indeed Skype.
With this new edition, the directory scheme is effectively flattened, making traditional Skype users available on calls placed through the Skype for Business client — formerly the Lync client.
The traditional Skype calling system, which uses P2P protocol over the Internet and the SILK codec for call clarity, is now bolted onto the Business edition as well.
But with a few other feature exceptions, the client remains quite similar.
