Viber, a mobile communications platform offering free messaging and HD-quality phone calls, announced today the release of Viber 4.1 for Windows Phone 8, bringing “Viber Out” calls to the platform for the first time.

With this new release, Viber users on Windows Phone 8 can make calls to their friends and contacts who have landlines or phones that don’t have Viber. Additionally, the update brings several key Viber features to the mobile Microsoft platform and expands the functionality of the app, including sending video messages, sending multiple photos at the same time, and hands-free Bluetooth support.

Viber just added the Viber Sticker Market to Windows Phone 8 platform in the 4.0 version released in Feb. this year. The Viber 4.1 version for Android, iPhone and Desktop was launched together with the Viber Out feature in December last year.

“With the addition of this critical feature to our Windows Phone 8 version, we are ensuring that the complete Viber experience is available on as many platforms as possible. This focus on cross-platform support is one of our most important commitments to our users,” said Talmon Marco, CEO of Viber.

Viber is now available for iPhone, Android phones and tablets, Windows Phone, Blackberry, Windows, Windows 8, Mac, Linux, Symbian, Nokia S40 and Bada devices over 3G/4G or WiFi connections. The app now claimed over 300 million users in 193 countries.
