Oh, there are such things as private MPLS networks, which is what i suggested. That would beat the pants off a T1 or DS3, directly connecting layers 2&3 while giving a layer 2 experience. It might be different if it were an "internet port also", but while that is a choice, MPLS "labels" things like voice ingress/egress, and prioritizes it, so I would beg to differ with the assumption that it would "add latency" unless it was not properly designed or configured.
