Hi

I found on AEP logs that when a customer does not say anything we get a NO_INPUT( in front of the SpeechFail in AEP logs) which is being handled by sending a DF_SYSTEM_NO_INPUT event to dialogflow that is fine.

But I can see in few calls NO_MATCH in front of (in front of the SpeechFail in AEP logs)which is being handled by sending a DF_SYSTEM_NO_INPUT event to dialogflow

My query is what causes NO_MATCH, who decides for a NO_MATCH and on what basis? Is it dialogflow or avaya? Under which scenario it will treated as NO_MATCH? As for some cases there were noisy recordings and we NO_MATCH and for some no recording was found


I am attaching the screenshot of NO_MATCH from AEP logs

Thanks

You would need to talk to the platform people. I would think EP throws the error first.

What does NO_MATCH mean? With what it is matching ?

It is generic VXML event. In generic sense, it is try to match some grammar but in case of Dialogflow, I am not sure. That's why you need to ask the platform people. I can't answer this here.

In DefaultDialogflowAppV3, the eventprops:name as DF_SYSTEM_NO_INPUT. Despite this configuration, after a brief period of silence, I anticipate hearing the No Input prompt, but it doesn't seem to be triggering as expected. Is there a specific configuration change required to ensure the No Input prompt is played?

Attached the log

So it looks like EP did process the EventPrompt and try to send the event to Dialogflow. Maybe it is because of the existence of the <prompt> element, it is not sending the event. Can you try removing the prompt item from EventPrompt node in the node editor. It would be like the picture I attached
