Snipped from the overall article: Perhaps an even bigger concern is that long-distance access charges were set at certain rates based on existing traffic volumes with the goal of helping telcos in high-cost areas cover their network costs. Until the Universal Service and inter-carrier compensation systems are reformed, the only solution that achieves that goal is one that would require VoIP providers to pay long-distance access charges at the same rate as other carriers.
Kasper added that if the industry were to go to a bill-and-keep arrangement, that would give telcos added incentive to move toward SIP traffic exchangea move that would help modernize the nations voice services infrastructure.
This is the part of the article that I like best! From there it's a short hop to things like G.722.
