C2Call SDK for Communication on Mobile Apps and Web Browsers

C2Call GmbH has been developing video chat, voice calling and messaging solutions for the computing cloud since 2008. As one of the pioneers in mobile communication over Internet Protocol, we launched FriendCaller back in 2009.

Today FriendCaller has more than 11 million registered users across all popular mobile communication platforms; including Apple iOS, Android devices, on Facebook, and on desktop web browsers.

Our SDK will soon be available for Mobile app developers free of charge. By integrating C2Call’s technology into their mobile apps, developers will now be able to have their users communicate across multiple apps, on multiple platforms. App users can then use video chat, rich media messaging, group audio and video calls and share location info with other users, all within one app!

We use C2Call at our innovation centre for POCs of cloud based offerings for SMBs and are amazed how fast and easy to integrate their solutions is!
