We've been working on many new features and updates for VoxImplant, during this process we forgot to tell that video calls support is already available for iOS SDK. Now you can make video calls between iOS devices using the SDK, or video calls between the SDK and SIP endpoints. We use H.264 video codec in the SDK at the moment, so it's not that easy to implement scenarios like video call between mobile SDK and Web SDK (especially when it's in WebRTC mode), but we are working on that. Demo application and the SDK documentation was updated accordingly.
