Worst kind of voicemail a parent could receive

Apparently a 22 year old American soldier had left his mobile phone on during combat. He bumped against the side of a Humvee and the phone accidently phoned the last number it had dialed: his parents.

So his parents heard three minutes of their son engaged in combat: swearing, shooting and yelling for more ammo, until the voicemail abruptly stopped at three minutes.
They had to wait for more then two hours before they could get any news that their son was okay.

Here is the link to the voicemail.
