I've heard stories similar to this. When you aren't suppose to follow voices coming from nowhere or answer them. It's very interesting Bangladesh also has such a legend.
I actually heard a voice calling my name one time when I was in a cemetery but nobody around me heard it.
Though for this story it's not a ritual to bring someone "back to life" because the person who has paid isn't dead, just extremely sick and close to death.
