Windows Phone 8 support to capture SMS or a incoming call?

Question

Can we write 3rd-party app to capture SMS or a incoming call on Windows phone 8?

Answer 1

There is Windows.Phone.Networking.NetworkOperators.SmsInterceptor class, but there is a note next to it "This API is not intended to be used directly from your code." so I'm not sure if we can actually use it or not?
