[Freeswitch-users] Example of playing background music

[Alex Lake]

So how can I stop the music here?
I'm a little baffled, as I thought that if I did a uuid_bridge of that 
leg and another, it would just join them together, the music would stop 
automatically and allow talking, but it doesn't seem to be working out 
like that!
