Ok here it goes.
Have a special need for a group.
My boss want (for some reason) that the welcome message don’t start playing imediatly, but that the caller first gets 2 normal rings.
Then the normal “welcome to bla bla bla bla please hold bla bla” message plays.
I guess a custom_app is in order, but what to do with the 2 inital rings? is there a “playback_ring,2” function
