[Freeswitch-dev] How to delay playback during an originate call?

I really need some help/advice on how to delay playback during the following originate calls: $ originate {ignore_early_media=true}sofia/gateway/name/number &playback(message.wav) $ originate sofia/example/1000@somewhere.com &javascript(test.js) I am hoping playback of message.wav or application (calling test.js) is invoked only after the call is established (connected). Is it possible to add some flag or channel variable, like media_bug_answer_req, to delay playback or call the JavaScript, Lua script, etc.?
