stolen macbook - facetime expert needed

Hi,
I need someone that is expert on facetime and that knows if it's possible to locate the ip address of who received a call.

This is what happened.
I got my apple macbook stolen a few months ago from my house.
I did a police report but nothing happened until yesterday,
when my girlfriend, called me on facetime.

I wasn't at home and my actual computer (another macbook) was turned off.
But instead of getting the message saying that i was not available for facetime, she saw another unknown person responding the call.

This happened because after my macbook was stolen i changed my apple id password, but a few days ago i changed it back to the old one that i was using.
I had automatic login on...

I will inform the police and contact apple, but i know it will take ages...

I know there's a program called commview that traces calls.
Anyone knows if it works with facetime?
Or if there's a way to get the ip of who received the call?
Please any help is very appreciated!

have you tried find my mac? its under the same iPhone app.. called find iPhone..

Best bet to do find my mac. These stories happen qutie often lately. Catch the theief via Cam, if you get him repsonding, make a screenshot! Report the person to police after that.

Thanks for sharing.
