I'm starting to test ACDC announcements now, did you ever work this out?
also, I see the 'moh' key is what controls the music when a caller enters the queue. I can't work out what the 'announce' key is supposed to do, it seemed like it would be for playing a short "Connecting you now" message when the agent picks up but it's not that. Anyone? 😬
edit: I added some more options to the callflows-ng monster UI to make setting up queues easier
