When you dial a phone number that's long distance but you don't dial 1
first, you get that really obnoxious high-pitched squeal before
getting the recording. It's been that way forever. Why is that
squealing sound necessary?

Probably a large dose of "thats the way we have always done it".
Its actually 3 tones. I don't recall the frequencies or durations,
google could probably find them for you. Its called SIT (Special
Information Tones) and its used by automatic callers to know they have
reached a bad number.

What an ingenious idea - too bad it's almost not needed now. Didn't
it confuse your friends tho?
