OK, thanks!

It worked perfectly.

Upgrading to F10 is not an option for now, but I'm glad to hear this is solved.

Skype sucks because it is proprietary, but I need to talk to Windows
users and ekiga is not a real option (I've tried ekiga and its voice &
video qualities are lower than Skype, besides the Windows client is
kind of broken).

I would like to hear some alternatives to use to talk from Linux to
Linux and from Linux to Windows.

Thanks!
