RE: VoIP QOS best practices

Jason,

I believe Global Crossing supports those sites, keep in mind I don't
sell their product, but UUNET should as well.

Providing your sites are local to the same ISP, that would be fine.  
Worst case scenario and probably a more likely scenario in most cases 
is that company A has a satellite office in Boston, one in Sydney and 
one in Tokyo while their head office is in Toronto.  Not a very wide 
range of providers who can reach those areas, not to mention wether or 
not they can deliver MPLS.
