Sending DTMF to the caller is sometimes necessary (automating IVR navigation, perhaps). Use the send_dtmf callflow to do so.


    "module": "send_dtmf",
    "data": {
        "digits": "123ABC#",
        "duration_ms": 2000
    "children": {}
  • digits is a string of DTMF to send.
  • duration_ms is how long of a tone to send each DTMF (and optional)

The above example would send "1", "2", "3", "A", "B", "C", and finally "#", each as 2 second tones.
