The DTMF element is used to send digits on a live call. This will usually be used to automate the process of navigating through an external phone tree (IVR).
Digits are sent in the background when the
async parameter is set to
true, so the call will jump to the next XML element when the first digit is sent. Use the character
w for a 0.5 second delay and the character
W for a 1 second delay. Allowed values:
Proceed to next element after the first digit is sent.
Allowed values - true, false. Default is true.
