[Freeswitch-users] Example of playing background music

[Alex Lake]

Is it possible in Lua to do something like....


playback_uuid = GetTheUuidFrom(session:execute("bgapi uuid_broadcast 
<a-leg uuid> nicemusic.wav"))

Then do some stuff on the b-leg

Then

session:execute("uuid_kill "..playback_uuid)

When I've tried it, I get....

I can only presume I've got the wrong end of the stick on these 
asynchronous jobs!

(BTW, dmExec is a wrapper around api:executeString)
