In the cisco world, all it takes is:
	interface <foo>
	  fair-queue

That's it.  That's all it takes on the ISPs part to provide a minimal
amount of QoS.  Cisco's documentation clearly lists how IOS handles
the queuing.  It's not full policy based traffic shaping with RSVP
and all that crap, but it's enough for a many situations.

Larry's situation is highly complicated by "the internet".  I've never
known anyone to be happy with VoIP across the internet.  It's hard
enough to make it work properly within a single ISP's network _with_
their assistance.  Across the wastelands, forget about it. (Why do you
think GRIC built their own global network for moving VoIP traffic?)
