Welcome to the Android C2Call SDK


C2Call GmbH leads the way in introducing next generation mobile and desktop browser based Voice and Video Calling solutions for the computing cloud.


With the launch of our SDK for mobile app developers, C2Call is providing access to the "one-click" video calling, voice and messaging functionality, which was only previously available through FriendCaller. By integrating C2Call's technology into their mobile apps, developers will now be able to have their users communicate across multiple apps, on different platforms using rich communication functionalities.
