Today, Skype, Microsoft owned VoIP services, allows all users to have a video group chat up to 10 participants on Windows PC; and up to 4 participants on Mac or Xbox. The company promises to deliver the same capability on other platforms soon.

In order to use the feature, all participants must have a Skype account and must have the Skype client software on their respective OS platform.
