I discovered the other day you can play music by voice control without actually saying the word 'play' first. This morning when I was doing this it misunderstood me and instead said 'Calling My Name' (those actual words). I cancelled it by repeatedly hammering the hang up button as you do, but when looking at my phone later the number it had started calling is the one that was on my sim card before I transferred my number to it. The only place this shows up is on the phones settings under 'My Number', so how come this has been added as a contact in the car? And why is it called 'My Name'?! It seems unlikely that I'd want to call myself anyway...

If you have a Samsung I belive they default my name with the sim that the phone is first set up with but you can change this!
