Windows Phone 10 universal app, event on incoming call, show custom toast/screen
<p>We need to show a toast or similar when the phone rings from a pre-defined number. </p>

<p>This is for an in-house application so we can use private APIs.</p>

<p>Long story short - when calls are routet trough our main number/line to our cell phones, we need to grab extra information from the phone central and display on the screen to the employee. </p>
