First of all: AMAZING game, best horror experience ever. Also, you HAVE TO use the PS4 headset with the microphone on.
It is actually really simple. Go to the clock (just because it is pretty safe there), wait till midgnight, wait till the ghost stop moaning, walk, REALLY SLOW to the radio (around 10 steps), go back to the phone REALLY SLOW: first laugh. (The key is the slow walk, since the game wants you to be scared).
Now, go to the clock once more (cause it is safe there) and talk or scream into the headset, really loud, or use this video to make the game think you are screaming:
Just talking or screaming did not work for me, but the goats videos never failed. When the game hear you screaming, you get the second baby laugh.
Go to the phone, the controler will vibrate, do not move, maybe try to focus on it without failing (some people say this part is not needed). It will laugh once more and then the phone will ring.
If you screw any part of it, cross the reset door and do once more, but it is really easy if done right and the goat video works like a charm.
Follow my steps, it will not take more than 3 minutes, also, you do not have to do anything else, not pics, no possession, just what I said.
My grammar errors are justified by the fact that I am a brazilian living in Brazil. I am also very stupid.
