WhatsApp updated its Windows Phone app on Tuesday adding the voice calling feature that was rolled out to all Android, BlackBerry, and iOS users' months ago. With the addition of voice calling, the WhatsApp Windows Phone app now allows voice calls over mobile data or Wi-Fi - also called VoIP or voice over Internet protocol.
The WhatsApp Windows Phone app update (version 220.127.116.11) also brings new features such as sending audio files (which is currently available on Windows Phone 8.1) apart from the VoIP-based voice calling feature. The updated WhatsApp app for Windows Phone is now available to download.

The Windows Phone store listing notes that WhatsApp Calling is available on Windows Phone 8 and above. It also adds that users cannot access 911 and other emergency service numbers through WhatsApp Calling. The voice calling feature is now available for all major platforms, namely Android, iOS, BlackBerry 10, and Windows Phone. Android was the first platform to receive the WhatsApp voice-calling feature in March followed by iOS and BlackBerry in April.
Windows Phone was due to receive the WhatsApp voice calling feature with the company back in April revealing the upcoming addition via a support team email to a user. The team had suggested that the feature was "still in the works" for the platform, and that it could not provide an exact time-frame for the release.
WhatsApp has already become the most widely used instant messaging app and back in April crossed 800 million monthly active users, according to WhatsApp's CEO and co-founder Jan Koum.
