I know how the Internet works.  I'm about to get my own AS for 7 sites in 
the US and 2 in the EU with more to come.

If both endpoints share a common ISP, its ALMOST as good as having a private 
IP link.  The data does not cross peering points and your provider is solely 
responsible for the quality of the traffic.  Better than that is to purchase 
layer 2 services available from MANY providers.  If you get your own AS, you 
can then peer with your VoIP partners as well as one or more transit 
providers.  This then provides a failover if your private link goes down. 
IP connections can be made much more fault tolerant than TDM connections at 
a much lower cost.
