How do you find your facetime call history on iphone/ipad?

This question is mostly tailored for the iPad. When I got to the facetime app on the ipad, I see a list of people I've called and the **last** time I called them, but I can't find anywhere that shows **all** the calls to a certain person. Does anyone know how I can find this information on the ipad? On the iPhone, there is a similar issue if you go to the facetime app. However, if you go to the phone app, it shows the call history, but there is no phone app on the iPad.
