This sound clip is from:

DTMF has generally replaced loop disconnect ("pulse") dialling. Each key you press generates two tones of specific frequencies. So that a voice can't imitate the tones, one tone is generated from a high-frequency group of tones and the other from a low frequency group. Long versions of DTMF tones as MP3 files to download and to play.
