It's my jackleg appraisal -- I'm not an attorney much less an FCC specialist
attorney -- that that subjects your service to regulations and restrictions
that don't pertain to people who do it the other way; you are simply a VoN
carrier, competing with all the other VoN carriers like Vonage; if you *do*
give your own traffic priority, then you're violating... title II? Some 
net neutrality provision that they don't cause they're not *moving the calls*
"over the Internet".
