I doubt Microsoft will ever publish "Skype for FreeBSD" :) But "Skype for Linux" still works and since FreeBSD 10.3 we can use it too.

# cd /usr/ports/net-im/skype4 # make install clean
- Select VIDEO if you want, although I haven't tested it yet
Skype 4 requires two things: linproc filesystem to even start (described in the article linked above) and a PulseAudio config if you want to hear anything.
Create pulse config in your home ~/.config/pulse/daemon.conf with this:
