What video calling software do you use for Fedora?

edit

Have you tried Firefox Hello? It is the easiest way to connect for free over video with anyone, anywhere.It doesn't require you to install any plugins! You can make calls to anyone using a latest Firefox browser on most Operating systems ( and that includes Firefox browser for Android).

If you want to use Ekiga or any other similar software for VoIP or Video call, you may need SIP account. Register for a SIP account with a SIP compliant VoIP provider and the other person whom you want to call should also have a compatible soft phone to receive your video call. After configuring your softphone, you may test it by calling test accounts. For instructions, you may click here.

I would also suggest to try Firefox Hello, great service without need for another account on some service. Works well and all you need to do is to share URL with person you want to talk to.

I heard from few people that Jitsi is also good although I didn't have much luck with it myself, but is definitely worth a try.
