WhatsApp starts rolling out voice calling feature to Android users

NEW DELHI: After testing the feature with select users, it appears mobile messaging service WhatsApp is now rolling out the much awaited internet calling functionality to a wider set of people. Earlier on Friday, a number of users of WhatsApp's Android app were able to get the voice calling feature activated by simply receiving a call from a user who had the service turned on. This meant that initial testers were able to extend it to their friends who further helped other WhatsApp users join the club. However, this invite system is not working for all users. We were able to get the voice calling feature activated on our Android phone after receiving a WhatsApp call. Although, we were able to make voice calls to other Android and BlackBerry 10 users with the latest version of the app, the feature was not being activated for all users. It's possible that WhatsApp may have set a limit to the number of users one could invite or is only allowing a limited set of users at this time to test its networks.   TOI
