First, please make sure your phone carrier and pricing plan both support call forwarding. Some carriers may not have the call forwarding feature included in your plan by default, neither may your pricing plan. The app will work best with busy, unanswered, and unreachable calls forwarded only, but if your carrier can only forward (or not) all of your calls, – that’s OK too. The app needs any call forwarding to work.
Second, please visit the App Store and ensure that you have the latest version. Even if you do, you may want to delete and reinstall the application just to be safe.
If it still does not work, please contact us at firstname.lastname@example.org.
