Facebook to test VoIP calls directly on their site :

In recent days some facebookers have noticed a new "Call" button during the visit of the profiles of their friends. And when you click the call button, a box of Facebook has opened with the word "vocation" icon next to our friend.

The logical reason to show up this new button could be the company that integrates your Skype contacts Facebook. Now we see the direct integration into the Facebook site itself. Could it be? If true (and it seems to be), then this would be a great step forward. Now we just need some action FaceTime iPad 2 and it would seriously heavy stuff.
