Google hangout / telephone / voip input to web app

I am currently building a web application and was exploring if there is a way to parse an incoming voip call information.

For e.g.: I have a list of contacts with phone numbers on my page. when I receive a call on my hangout in that browser, I need to parse the caller's phone number and search for that phone number in the list and display that contact details. I am not tied to Google Hangouts. Any similar libraries / frameworks are fine. The application I am building uses AngularJS.
