    • Does XMPP for chat, Sip for voice. I like the open federation with most XMPP accounts and it's still working as a chat client among Gmail accounts.

    • it does everything skype does and more, including end-to-end voice and text encryption, which skype does not.

    • Jitsi is a front-end capable of using multiple protocols. Using XMPP, it can provide text, voice, video, and screen-sharing calls as Skype would. On a server with MUP enabled, it also allows groups. File sharing may be slow, but no slower than Skype. As such, Jitsi can functionally replace Skype.
