Just thought I would write in on the off-chance that no-one has noticed this, though I’m sure someone must have done already.

I was thinking that the normal 3 note tone when you misdial a number or leave the phone off the hook sounded, to my ear, identical to how the Three Note Oddity ( tcp_d1_12_three_note_odditiy_irdial.mp3 ) would sound if it was upped by an octave and played at double the speed.

I decided to stick the two into a wave editor, with the Irdial 3 note oddity in the left channel, and the telephone message in the right, and it turns out that the 3 notes are exactly the same.

I have no idea what it means, but it just seemed like a cool co-incidence. :-)

(with the phone notes slowed down by 50% and shifted down an octave to match the Irdial)
The phone error in this is from the Telewest system, been a while since I’ve heard BTs but from memory I think the tones are the same.


The never-ending strangeness of Numbers Stations; a constant source of pleasure.
