Your title is different from your question. If you're concerned about direct P2P connections, last I checked, Skype still sends voice traffic directly to the peer. I had checked some months ago using a packet sniffer while talking with a known peer. I'm on a mobile device so I can't confirm now, but looking at my wireless router admin console, I still see the UPnP ports Skype has mapped for itself. However if you want to avoid integration with the Microsoft universe (which should be opt-out IIRC, though I haven't installed Skype on Windows in ages), you may need to look elsewhere. I was about to suggest Google Hangouts, but that's just inviting integration with another universe :-) WebRTC-based solutions may be a decent option long term, but I'm not convinced they'll work as well as Skype or Hangout, because its NAT traversal is somewhat limited, so some peers may be unreachable, especially if corporate networks are involved. Skype and most P2P software perform a lot of hacks to get past NATs. Hangout, AFAIK, doesn't have these problems as it is server-based.
