It has audio/video chat for almost any other service except Skype. But the biggest issue I have with Jitsi is it doesn't have Skype support. There is also no 'Now Playing' feature for music. There are no themes, there isn't even a universal away message. Who doesn't want as much privacy as possible?My complaint with Jitsa is the fact it's pretty basic outside of encryption and audio/video chat.
Being able to video chat on any IM network is nice adding extra security like Jitsi is even nicer.
