No; if you look at an old rotary phone, you're counting the number of finger holes in order to determine pulses.

To dial a 0, pulse the line 10 times.

Unless you are in New Zealand - the dial is numbered "backwards" there so 0 is 1 pulse etc.

Oh wow, thank you for the memories :) I grew up in New Zealand when everything was pulse dialing and had an American modem that my father got us, so in order to dial any phone number I had to rewrite it by subtracting every digit from 10.
