Facebook highlights video chat with new 'call' button

Facebook is testing out a new "Call" button in profile pages to promote its video chat capabilities.

Despite launching the service in a partnership with Skype nearly a year ago, Facebook may feel the pressured to amp up its video chat's visibility with competition from services like Google+ Hangouts and the recently launched Airtime.

TechCrunch first noticed the little button showing up at the top of people's profiles.

It seems like the person needs to be online for the Call button to show up. A glance at my list of friends online seems to confirm that, but nothing official from Facebook yet.

Without the new button, the only way to know there is video chat is the tiny video icon at the top of chat windows.
