You can use the DTMF element to send digits on a live call — for instance, to automate the process of navigating through an interactive voice response (IVR) tree.
If you set the
async parameter to
true, Plivo will send digits in the background, so the call jumps to the next XML element when the first digit is sent. Use the character
w to add a 0.5 second delay and the character
W for a 1 second delay.
Proceed to next element after the first digit is sent.
Allowed values: true, false
