Call gets dropped too early on Dialogflow endInteraction #11

Open rjp44 opened 3 years ago

rjp44 commented 3 years ago

In order to honour the DialogFlow endInteraction flag, the bridge listens for MQTT dialogFlowEvent messages emitted by dialogflow-rtp-audioserver on intent recognition and triggers an ARI continueInDialplan to drop the call when it sees an intent with endInteraction set.

This immediately drops the call whilst rtp-audioserver still has the DialogFlow audio in its queue to send to Asterisk so any audio emitted by the last intent is lost.

I think the fix involves having rtp-audioserver send an additional dialogFlowEvent message when it has sent all outstanding data to Asterisk, and delaying the call drop here until we receive this.
