Viber, a VoIP service claiming more than 200 million users, marked its third birthday by releasing Viber 4.1 which includes the full global launch of Viber Out, a new feature that allows users to make low-cost calls to any mobile or landline phone number.

Viber Out enables all Viber users to call anyone worldwide on Android, iPhone and Desktop, coming to Windows Phone in the future. Purchasing credit for Viber Out can be completed either through a simple in-app purchase via either the Google Play Store or the Apple App Store or using a credit card via Viber Desktop.

Additionally, Viber Out claimed that it has lower price-per-call than other competing services due to lower per minute rates and the omission of connection fees.
