To build on Josh's response, app_config is essentially the arbitrary data field that can pass all the information you want to the application from Asterisk. We wanted to leave this open-ended intentionally, with the idea in mind that it could be used for other things besides TTS and STT.

There should be another response type to handle this, with defaults in place if Asterisk doesn't receive this particular kind of response from the application.
