DTMF collection

[Chun-Yang Chen]

Hi,

I'm trying out the DTMF collection via Go API. QueryInput_Dtmf is used to deliver individual digit to the flow.  In my sample dialogflow, I have a parameter set with DTMF enabled along with max-digits=4 and endpointing timeout duration = 5.  When I use QuerInput_Dtmf to send a digit, it would advance to the next block rather than waiting for more digits to be entered.   Here is a snippet from the log.   The flow is asking for 4 digits SSN. But as soon as dtmf 1 is entered. It moved on to the next prompt. 

Q: Is QueryInput_Dtmf meant to be used as a way to deliver individual DTMF digit and the dialogflow can manage the digit buffer and timers filing in the parameter ?

Q: I can see interactiveVoiceResponseSettings/DtmfSettings are presented in the diagnostic_info.  Is there a reliable way to retrieve this information if the client is supposed to manage the digit buffer?

Thank you.
