I want to insert a queue of voice recordings into a call, and be able to stop them all. Doing both via the event socket. Currently I'm doing: api uuid_broadcast $uuid fileName1.wav both api uuid_broadcast $uuid fileName2.wav both And stopping the audio with: api uuid_break $uuid all That works quite well, except for two problems: 1) I can't use it because when the audio is playing the parties can't hear each other talk. 2) There is a slight delay of about half a second before the audio starts (though I'm guessing this can't be helped.) Previously I'd used: api uuid_displace $uuid start fileName1.wav 0 mux But I don't think I'd been able to queue up more than one file with that. There's a few other possibilities that I've thought of, including going into a js/lua script and looping inside that, or changing the call into a conference, and using the conference commands. Rather than mess around trying lots of ideas, I'd rather focus on the one best approach - any ideas? Cheers, Fraser
