Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center. The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone.
Other multi-frequency systems are used for internal signaling within the telephone network.
Binary data transfer
Keypad
DTMF keypad frequencies (with sound clips)
The tone frequencies, as defined by the Precise Tone Plan, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies. The frequencies were initially designed with a ratio of 21/19, which is slightly less than a whole tone. The frequencies may not vary more than ±1.8% from their nominal frequency, or the switching center will ignore the signal. The high frequencies may be the same volume as -- or louder than -- the low frequencies when sent across the line. The loudness difference between the high and low frequencies can be as large as 3 decibels (dB) and is referred to as "twist." The duration of the tone should be at least 70 ms, although in some countries and applications DTMF receivers must be able to reliably detect DTMF tones as short as 45ms.

DTMF decodes and encodes DTMF (Dual-tone multi-frequency) tones trough the phones speaker and microphone.
Encoder: Always 2 tones are assigned to each key.The length of the tone and the pause between the tones can be set from 35ms to 1500ms.
A total of 36 marco's can be used to play phone numbers, ham radio auto patch numbers, amateur radio echolink id's any many more.The 36 macro's can be saved to the phones/tablets memory. This way a unlimited amount of macros can be used. The DTMF tone length and the pause between the tones can be adjusted.
Decoder: The decoder detects the DTMF tones and prints them on the screen. A sophisticated algorithm detects the tones even in noisy environments.

Project Description: Use a MT8870 DTMF module with an Arduino UNO to control a small servo motor. The DTMF module gives the Arduino super-powers and allows you to control the Servo motor in so many ways. In this project we will control the servo motor through:
1) a YouTube Video
2) a voice recorder
3) A web application (Online tone generator)
4) A smart phone app (DTMF Pad)
5) A touch tone phone to cell phone call
All of these using the same exact Arduino code. But how???
The DTMF module decodes Dual Tone Multi Frequency signals and converts them into a binary-like output. You use the Arduino to interpret the output and control the servo motor.
The DTMF module is powered by the Arduino's 5V line.
The full tutorial including code and diagrams can be found on my blog: http://arduinobasics.blogspot.com.au/2015/08/mt8870-dtmf-dual-tone-multi-frequency.html

Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center. The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone. It was developed by Western Electric and first used by the Bell System in commerce, using that name as a registered trademark. DTMF is standardized by ITU-T Recommendation Q.23. It is also known in the UK as MF4.
Other multi-frequency systems are used for internal signaling within the telephone network.
Introduced by AT&T in 1963, the Touch-Tone system using the telephone keypad gradually replaced the use of rotary dial and has become the industry standard for landline service.
Prior to the development of DTMF, automated telephone systems employed pulse dialing (Dial Pulse or DP in the U.S.) or loop disconnect (LD) signaling to dial numbers. It functions by rapidly disconnecting and re-connecting the calling party's telephone line, similar to flicking a light switch on and off. The repeated interruptions of the line, as the dial spins, sounds like a series of clicks. The exchange equipment interprets these dial pulses to determine the dialed number. Loop disconnect range was restricted by telegraphic distortion and other technical problems[which?], and placing calls over longer distances required either operator assistance (operators used an earlier kind of multi-frequency dial) or the provision of subscriber trunk dialing equipment.

Dual-tone multi-frequency signaling (DTMF) is used for telecommunication signaling over analog telephone lines in the voice-frequency band between telephone handsets and other communications devices and the switching center. The version of DTMF that is used in push-button telephones for tone dialing is known as Touch-Tone.
Other multi-frequency systems are used for internal signaling within the telephone network.
Binary data transfer
Keypad
DTMF keypad frequencies (with sound clips)
The tone frequencies, as defined by the Precise Tone Plan, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies. The frequencies were initially designed with a ratio of 21/19, which is slightly less than a whole tone. The frequencies may not vary more than ±1.8% from their nominal frequency, or the switching center will ignore the signal. The high frequencies may be the same volume as -- or louder than -- the low frequencies when sent across the line. The loudness difference between the high and low frequencies can be as large as 3 decibels (dB) and is referred to as "twist." The duration of the tone should be at least 70 ms, although in some countries and applications DTMF receivers must be able to reliably detect DTMF tones as short as 45ms.

DTMF CONTROLLED HOME AUTOMATION SYSTEM USING MICROCONTROLLER Project Output Video -
http://www.electronicshub.org/dtmf-controlled-home-automation-system-circuit/
The main principle of this circuit is to control appliances like light and fan using DTMF technology. DTMF encoder is present in your mobile and decoder is HT9107B IC. Mobile jack is connected at 1nf capacitor. Mobile jack consists of two wires (Red and black). Red wire is connected to the decoder IC and Black is grounded. When a button is pressed from mobile it generates a tone which is decoded by the decoder IC and it is sent to ATMEGA8 controller. Controller then checks for input and it produces the output according to the code written to it. Get detailed information about this project circuit diagram, working and applications in the post link mentioned above.

DTMF (Dual Tone Multi Frequency) - термин обозначающий тональный набор, когда вы нажимаете на кнопку телефона раздается звук (тон), являющийся комбинацией низко- и высокочастотного тонов (поэтому и называется Dual ), такая система включает в себя восемь тонов, специально созданных что бы передаваться по сети с наименьшим затуханием и минимальным воздействием друг на друга. Допустим нажав на кнопку «9» Вашего телефона Вы услышите комбинация сигнала 1447 Гц и 852 Гц, простой DTMF декодер, который позволяет мне управлять любым устройством из любой точки мира, где есть сотовая связь.
Звоним на мобильный телефон (он уже поставлен на автоответ)
для управления используется два мобильных телефона -- один у вас в руках в качестве пульта ДУ, другой установлен в качестве приёмника. С вашего телефона поступает звонок, и при нажатии вами во время звонка клавиш, с мобильного телефона поступает многочастотный сигнал. Этот сигнал называется Dual-Tone Multi-Frequency (двухтональный многочастотный сигнал) (DTMF).
С помощью DTMF декодера , DTMF отдаёт команду

Anthouse
I just wanna lay down
The fever goes down
I just wanna set you free
I just wanna take time
To think about my life
and I know that you’ll be set to see
When you’re doing like that
I’m just burnin’ and
That’s what really is gonna make me sick
No more time for regrets
No excuse, I confess
I need another place to be
I just want you out of my mind
