Whatsapp is now on par with other instant messaging apps such as Skype, Line, WeChat and Viber, as it finally rolls out its very own voice-calling feature!

The feature is available for all Android users who updated their Whatsapp to the 2.12.5 version or they can just simply download the version via Google Play.
The new layout will have three tabs: Calls, Chats, and Contacts. Just a simple tap on the ‘Calls’ tab to select who you wish to call, is how you initiate a voice call, but both parties  need to have the latest version of the app in order for the voice-calling feature to work.

The feature is currently available for Android users only, but according to Venture beat, the feature will be available on iOS very soon.
