Registering a Custom href Protocol on Windows Mobile in JavaScript

I am developing a web-based mobile application, My application has a button that takes the user to the dialer where a USSD code is ready for the user to dial. This works fine on Android Devices and iOS devices.

<a href="tel:*222*263000000000#">Trigger USSD</a>

On Windows 10 Mobile that link triggers the People App or the Skype App. If this was a native app I know I could register a URI protocol to trigger the dialer. Is there a workaround in JavaScript I can use to target the dialer (Or Phone App) specifically such as registering a custom href protocol maybe.
