Accepting Calls​

Use SDK's default parameters unless otherwise required.

  • Camera: Default settings (usually front-facing camera).
  • Video parameters: Default 480 x 640 resolution at 30 FPS.

You may also specify camera and video parameters before each call. See setVideoConfig.

When rejecting or ending a call, the SDK handles internal processes automatically and notifies the peer about the rejection/termination reason.

Default Acceptance Method​

Upon receiving an incoming call request via onReceiveCall, use the accept method of RCCallEngine to answer.

Note

This method activates the default camera device (typically front-facing by default).

  • Sample code:

    engine?.onReceiveCall = (RCCallSession session) {
        engine?.accept();
    };

Answer with Specified Camera​

After receiving an incoming call request in the listener, use the following code to answer while activating a specific camera.

  • Sample code:

    engine?.onReceiveCall = (RCCallSession session) {
        RCCallVideoConfig videoConfig = RCCallVideoConfig.create(
        /// Activates rear camera
        defaultCamera: RCCallCamera.back,
        );
        /// Configures video parameters
        engine?.setVideoConfig(videoConfig);
        engine?.accept();
    };

Rejecting/Ending Calls​

Call RCCallEngine.hangup to terminate a call. Rejection and call termination share the same method—the SDK automatically informs the peer about the reason.

  • Sample code:

    engine?.hangup();
