When giving phone numbers (or addresses) it's common to say "oh" when meaning the numeral zero. One of those quirky language things.

For example, "six oh five main street" or for a phone number, "five five five seven oh one three".

So with the operator phone number, it's a numeral zero, but usually said as "oh" as in "dial oh for operator".

In the mid 20th century, it wasn't common to give phone numbers as a series of digits. The first two digits of the 7-digit local code were expressed as a word using the letters on those two digits. So a phone number was expressed as "word then five digits". Eventually it became common to use numbers only, and the use of letters fell to mostly a commercial phone number gimmick (e.g. 1-800-KEK-WINS. And no, please don't dial that, I have no idea whose phone it rings).

I don't think anyone would have ever used a single letter to express what to call.

Very clear public evidence about who is responsible for 9/11 would awaken the masses (and set the stage for arresting cabal as enemy)

From an emotional perspective, totally unambiguous evidence about 9/11 would be a 9/11 type event. Because it would make the public interpret everything they felt in a totally new light.
