edit : απαντηση απο support του viber
When using Windows Phone you may encounter sporadic delays in receiving call notifications. This is a known issue that is caused by Microsoft’s push servers.
We have developed a built-in bypass feature that should prevent you from missing future notifications if you have already experienced the delay once. However, we cannot guarantee that this will bypass the Microsoft issue every time.
We apologize for any inconvenience.
Best Regards,
