Hi Chris
That seemed to work I got audio in both scnearios, in the XML and LUA
script.
so the only difference between my originial issue and the successful moh
test. is that I was trying to playback a file and here we are playing a
local stream://moh.
I have changed all the files too chmod 777, is there any thing else on the
rights point of view that I need to know in order to get it to work?
I am grateful for any ideas or anything else that could help me understand
what the issue is
thanks
Marc
