The best way to make Video calls using WhatsApp™ web
Video Chat for WhatsApp™ Web - The awesome feature that's sorely missing in WhatsApp™ Web : Making Video Calls, which lets you create WhatsApp™ video chat room with a single click.
WhatsApp™ Web doesn't come with this feature, but, thankfully, Video Chat for WhatsApp™ Web fills that void.

Make conference calls for groups.
