Rolled out in February to a small number of people, the call feature then expanded to invitation-only by those who were able to get the feature. Now it's available to all Android phone users.
Now owned by Facebook, which paid $19 billion to acquire it, WhatsApp started life as a basic text-messaging app but one that also offered the ability to leave voice messages. The company has been promising to add a phone-calling feature, which would give the app the leverage to compete against similar services such as Skype and Viber. At last year's Mobile World Congress, WhatsApp co-founder Jan Koum said the voice calling would roll out to Android phones and the iPhone first, and then to Windows Phone and some BlackBerry phones.
