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.
