I have used ichat and have video conference with different people around the world, however sometime it says I have refuse to respond even though I have accepted the invitation or the other way around. Is it a bandwith or a firewall port problem ? I have looked in the forums on opening ports but that doesn't seem to work. So as of this momement it's only 50/50 that I can use the video conference with my isight. Is it my computer or is it something else. I travel a bit so I'm thinking it's maybe the broadband I'm using. Thanks for any insight on this.
