I will try that Terje.
When I added the policy "any any" today and commit the changes I got a warning that msn-base, ssl and web-browsing should be allowed as dependency apps also, but when I checked in https://applipedia.paloaltonetworks.com/ its not required. To double check this I shoot the command #show predefined application skype and those dependency apps were included. But again I've already tried and added them and still doesn't work.
I guess what I meant as an 'any any' rule was that it would be any destination and any applicaiton. This placed above all other security rules will let you know if this is a firewall issue or a network issue. If you still can't get to Skype with a set source address, any destination, and any application set to allow then it would indicate that your firewall isn't at fault here; something in front of your firewall is to blame for the issue.

I had the problem lately that chat and audio were working but video wasn't.
It turned out I was missing the "Jabber" application in the allow rule.
Thanks for the help guys. I did the allow all rule with one source and when Skype didnt work we realised its not FW issue. However, we pluged the machine directly with the router towards the internet and it didn't work also, then we change the DNS to public on (188.8.131.52) and everything was working perfectly. They have an issue with their DNS server.
I believe that might be the reason but honestly I didn't try changing the DNS server on the testing machine till I ran out of all options on PA.
