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.
