Online DTMF Tone Generator - Audio Check
https://www.audiocheck.net/audiocheck_dtmf.php
Dual-Tone Multi-Frequency (DTMF) is the signal that you generate when you press an ordinary telephone's touch keys. Over the years, DTMF has replaced Pulse dialing, the early type of telephone dialing in which short pulses were used to relay the dialed number. With DTMF, each keypress on your phone generates tones made of two specific ...

DTMF generator. One Sunday when I was extremely bored (perhaps I had a hangover, I don't remember) I wrote a PHP script that generates audio files containing DTMF signals for a given phone number. Using this generator I can enter a number on my computer, pick up my phone, hold the receiver towards my computer speaker, and play the generated ...
DTMF - Genave
Listen to a DTMF command code being send by an automatic encoder at a standard “Whelen” rate of 16 digits per second. The DTMF code you hear is 461####333. Standard Whelen timing is 40 msec mark / 20 msec space. Listen to a Genave decoder responding to a code sent at a blazing DTMF rate of 20/5 also known as 40 digits per second.
