[Freeswitch-users] Re - FreeSWITCH Lua CUSTOM events interrupting session:streamFile playback - is this possible?

[Abaci B]

I bumped in to a similar Issue where I have a large number of callers
listening to a file and in some cases I would like to interrupt everyone
listening to a specific file.
I tried deleting the file but the file is still being played back, I guess
it's either playing from cache or it's buffered, is there a way to not
buffer or cache the file?
I tried sending an even but the setInputCallback doesn't get triggered from
non DTMF on the channel, question is if there is a way to create an event
that will trigger the callback function (in lua) or if there is a way to
have the callback function listen to custom events, I'm ok if it needs some
patching of the code if someone can give me a clue.
