[Freeswitch-users] More playing with sessions in lua

[Anthony Minessale]

as soon as you play please hold there is no longer a chance for signaling
based ringback
you could have used the application ring_ready to send your phone an 180
ringing if you did not play the file
once you played the file you are responsible for sending audio to the
channel, think of it like a gui where the runtime loop takes input and you
must not do anything blocking in that loop and you can't play the file and
do something else at the same time without more threads which is not easy to
do from an embedded script.
