How to receive FaceTime calls through my iPhone's number on my iPad?

I have an iPhone 4S and I use FaceTime on it daily, now I have an iPad I would like to use my iPhone's number to receive iMessages and FaceTime calls, is this possible? This is instead of using my Apple I'd on the iPad.

Thanks

Added (1). Thanks for the help, I fixed it by adding the iPads Apple ID to the iPhones FaceTime in settings, then it shared all of the methods of receiving and I clicked the iPhones number on both the iPhone and the iPad.

Settings > FaceTime > & you should be able check the number as well as the email addresses associated with your Apple ID

on the iPad you are doing this of course.

The phone No links to the apple ID, all devices with the same apple ID

If the apple ID is the same on both devices - it will take the same calls
