buddy

I had my software programmed because of a faulty tcu unit, in doing so the bmw assist died and would not reinilize yesterday. However today on the way to the dealer i tried it again and it worked but set the car up as being red not black upon trying to call bmw assist it dialled 911 i promply ended the call only to be called back by the police deparment with a hang up on 911 call from your cell phone. I explained to the officer the problem and she concoured but i wanted to know the number she called back thinking that if she can call me then it has to be a number to a cell phone if she can call why cant others if i can find the number out is there a way to find this infor without calling 911 back and asking them?
