That did it!

I had to add both lines below in order for it to work:

    <action application="set" data="instant_ringback=true"/>
    <action application="set" data="ringback=${us-ring}"/>

Now, suppose I call a number that's busy...do I hear a ringback followed by a busy signal?

Out of curiosity, you might try this trick:
<action application="set" data="instant_ringback=true"/>

I'm curious to know how that works with your setup.
