List of facetime calls from my Apple Account?

I have had the belief that my brother stole my iPod for quite a while, but other than his reactions, I've never been able to find proof. Every so often I get a notification that "<My name>'s ipod" has connected to a new computer, used facetime, etc from my account. I was wondering how/if I could look at a list of outgoing facetime calls from my account, and see if one of the numbers can be called, and I can develop proof, or figure out what happened to it. Thanks.
