I’ve had the same problem. I’m testing on two clients and one server, all running Windows XP SP2. At first I couldn’t even get the phone icon for voice chat to work, but letting port 5222 through the firewall on one client seemed to fix this. I then tried a voice call but I received the message listed in the original post. I disabled the firewall on the clients, but this didn’t work. I then disabled the firewall on the server and still no luck. I’d be grateful for any assistance you can offer.

Sorry, I meant to say that I allowed port 5222 on the server. ;o)
