Before DTMF, telephone systems used pulse dialing to signal numbers. In pulse dialing, the connection between the handset and the central switch board is disconnected and reconnected rapidly. This was accomplished with a rotary dialer that would interrupt the connection as it spun. It is also cal...
DTMF is a technology that sits inside touch phones. Every key on a telephone keypad generates a specific “tone” or sound when pressed. These tones transmit over a voice channel to particular technology within the contact center. The technology listens to each tone before translating them into ...
Since a telephone tone has two frequencies, it is known as a dual tone multi-frequency, or DTMF tone. There are 16 such tones that may be utilized with this technology, but, typically, a phone uses 12. The tone decoder works by reading low and high frequencies and pairing them to ...
DTMF tones are an example of anin-band signaling protocol; that is, signals are sent over the same communications channel as the primary data on that channel. For DTMF tones that means that tones are in the same frequency range as human voice - any DTMF tones produced can be heard over ...

is an automated telephone system technology that enables callers to receive or provide information, or make requests using voice or menu inputs,without speaking to a live agent. IVR is powered by a pre-recorded messaging or text-to-speech technology with a dual-tone multi-frequency (DTMF) int...
This technology is called dual-tone multi-frequency signaling (DTMF). For example, you could offer: Sales. Support. Accounts. But you could also offer submenus inside each of those options. So, when someone presses 3 for accounts, they get a second menu. This could include: Make a ...

Most IVR systems use dual-tone multi-frequency tones or DTMF tones to interact with your caller, which is just a technical way of saying that it uses the caller’s touch-tone phone keypad. Contact centers also support voice response through speech and voice recognition technology in their IVR...
