May be recognized as SIT (although we don't know if they have a telemarketer problem there).
Three pulses of 450 Hz, 100 ms on and 100 ms off, followed by
a fourth pulse of 450 Hz, 400 ms, and 400 ms of silence before the next iteration.
We have four iterations here. Algorithmically generated with dmTS.
