The Viber 5.0 update works cross-platform because it also released new versions of its desktop application for Windows, Windows 8 and OS X.

Originally, the video call feature was limited to desktop application. But with Viber 5.0, mobile and desktop users can now transfer video calls on both platforms without dropping a call.

Viber CEO Talmon Marco, said they're "delighted to bring video calling to mobile."

"Users can now make video calls from their phone and desktops, they can always talk in the way that's most convenient for them, wherever they happen to be," Marco said.

In addition to Viber's new features, version 5.0 also includes QR code scanning for quick and easier contact management and a number of specific OS enhancements.
