How to intercept incoming call event on Windows Phone 10?

Question

Mobile development

Salute colleagues! I'm thinking of a scenario for a CRM application for wm10. Tell me how you can intercept the incoming call event + caller number in order to display additional information about the caller?
PS. By the way, maybe someone already knows something ready to eat? I installed about a dozen applications from the market, nowhere is this.
