i do believe skype is blocked because it said it was when i tried on skype, if i am wrong, tell me, FireRTC works.
the link redirects me to google.co.uk ??
uummm... it must already be down... ill edit it, the number still works tho
the popup also included my ip and ISP so that may be why it doesnt work, especially since you are in the UK and i am in the US
