I wanted to know if anyone knows of any numbers that make weird tones, test noises, stuff like that. Also any other kind of "special" numbers. I would really appreciate it. Thanks.
I know alot of areas that have bell style payphones have call back numbers, they will make weird tones and then when you hang up the payphone will ring back. The call back codes are different depending on the area you are in. I'm still trying to learn them all.
