If no one speaks than you can't differentiate a false alarm from someone who can't breathe, or is hiding from an attacker, or is too hurt to put the phone to their ear.
It's a massive nuisance unless someone gets on to say it was a mistake...and if someone didn't notice their phone buzzing before it made the call they aren't gonna pick up.
