The free feature, released Thursday in a “beta” test version of Skype’s software for Macs and PCs, expands on an existing partnership between the companies.
Since July, Facebook has allowed users with webcams on their computers to make Skype-powered video calls on the social-networking site.
According to US media, Skype lets users make calls, conduct video chats and send instant messages over the Internet. Its basic services are free, while users pay for services such as calling regular phones from a computer.
Jonathan Rosenberg, Skype’s chief technology strategist, said the company wants to help a billion people communicate, particularly with video. Working with Facebook “is really taking us a big step closer to that goal,” he said.
