Dtmf frequency for 3
WebDTMF Tone Generator Introduction 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. WebDTMF, or Dual-Tone Multi-Frequency tones, are in-band telecommunications signals sent over voice frequencies. Commonly used over telephone lines, DTMF tones are also commonly called Touch …

The DTMF deviation for FM, such as 2.5 kHz peak deviance, should be 1.65 Hz or less if you are using it. DTMF signals are an “in-band” signaling system, so we'll typically hear the tones being sent over the air if we just listen on the frequency.
