Jason,
My strategy would be to use the same carrier at point A and point B and
purchase some kind of high-priority MPLS switching config between the
two. I believe Global Crossing offers something like this where they
differentiate between the proletarian traffic and the uber-business
traffic.
The other thing to keep in mind is that QoS only comes into play when
you saturate your links.

Subject: VoIP QOS best practices
Looking for some links to case studies or other documentation which
describe implementing VoIP between sites which do not have point to
point links. From what I understand, you can't enforce end-to-end QoS
on a public network, nor over tunnels. I'm wondering if my basic
understanding of this is flawed and in the case that it's not, how is
this dealt with if the ISPs of said sites don't have any QoS policies?
