George's phone number

[bicyclesonthemoon]

In the library, when you have to contact the head librarian (George) the robot is trying to call George by phone but nobody is answering.
The robot quickly dials the phone number.

Did you ever wonder what George's phone number is?
I did.

I opened the relevant sound effect file (phone_dialtone.wav) and made a spectrogram of it:

From it I could decode the DTMF to get George's phone number:
It's 373376863.

This is quite a discovery. Have you called?

No.
But actually, it looks like there is no sense in doing this:

1. Further search shows that the sound effect phone_dialtone.wav is taken from freesound org: https://freesound.org/people/CGEffex/sounds/95112/ so the number is not that specific to the game. Somebody on freesound made it up.

2. It's a 9 digit number. It's a valid local number length where I live but it doesn't have the country prefix, so even if it works I would be calling someone in my country.
