Investors might still be scratching their heads overĀ Facebook's (NASDAQ:FB) $19 billion buyout of mobile messaging powerhouse WhatsApp.

To be fair, it's understandable for investors to be at least a little skeptical over paying $19 billion for a revenue stream weighing in somewhere in the neighborhood of a paltry $20 million last year. However, Facebook's acquisition plans with WhatsApp were always grounded more in the future, rather than the present.

And in keeping with working toward its full potential, WhatsApp recently announced a move that should at least help convince Facebook investors their money was well spent.

WhatsApp on the move
In another recent announcement from the messaging platform, WhatsApp recently disclosed that it plans to move beyond simply sending IP-based messaging. At the Mobile World Congress, WhatsApp announced it plans to add voice over IP calling in the upcoming months.

This keeps in line with Facebook CEO Mark Zuckerberg's explanation that lies far beyond just messaging, and instead in the potential to connect what could be more than one billion people eventually.

In the video below, tech and telecom analyst Andrew Tonner looks at WhatsApp recent announcement and what it should mean for Facebook's investors.
