Connecting iPhone 5 with MacBookPro (for making phone calls)

Hi,

I would like to know, if it is possible, to accept incoming calls on my iphone 5-number on the macbook and making calls on the mac via the iphone?

Is there an App or any programme or even an onboard-solution to realize this?

I am really an amateur in computer things so I need when it is possible a really step-by-step-description. I couldnt even connect my iPhone with the Mac via Bluetooth.

Thanks a lot for your help in advance!
