[Freeswitch-users] Interaction between event handler and streamfile (avmd specifically)

[Anthony Minessale]

whatever you return from the callback besides null undefined blank
string etc will be returned from streamfile so you want to just return
something like "replay" vs "stop" vs nothing if you want it to keep
playing.  then you can decide from there.
