Dual Tone Multi-Frequency (DTMF)
DTMF full form is Dual-Tone Multi-Frequency, the keypad tones generated when a caller presses numbers on their phone during a call. These tones are commonly used in IVR menus for actions like selecting options or entering information.
In contact centers, DTMF enables reliable call navigation and self-service, especially when speech input is not available or when accuracy is critical. It helps route callers faster, capture inputs securely, and reduce agent workload for simple requests.
