DTMF stands for Dual-Tone Multi-Frequency. This is the technical term for the sounds you hear when you press the keys on your telephone. DTMF does more than just let you know that you pressed a key. Each key has its own sound. Each sound is actually two tones played simultaneously. One of these tones is a low-frequency tone; the other is a high-frequency tone.
