Skype now has a repository for RPM based distributions. It’s still labeled as beta, but they are retiring the old 4.3 version after June 2017, so it’s the version you should be using. This is how you install the new Skype for Linux on Fedora 25.
Installation is quite easy:
sudo dnf config-manager --add-repo=https://repo.skype.com/data/skype-stable.repo sudo dnf install skypeforlinux
