Re: US slaps fine on company blocking VoIP

It's a portable scenario, and it doesn't matter which port you block.
Flip it around:
HTTP can transit on any port. Block port 80 and see how long you last.
Here's another take on it. Don't think of this in terms of tracing packet routes. Trace the path of SLAs, AUPs, and peering agreements between Vonage and those blocked customers.
Madison River buys transit from someone. At some point, their contractual obligations for that peering arrangement are passing on elements of other peering agreements, which in turn pass on still more. This is the essential layer of cooperation and good faith that make the internet work.
On the other end, Vonage, or any Voip provider, for that matter, has purchased peering and transit with the reasonable expectation that they can pass end-to-end traffic, unfiltered. It would not be entirely unreasonable to see a peering agreement terminated for this behavior. I am not a lawyer, and I am not privy to the details of the peering agreements for the networks between Vonage and their end customers, but it's their faith in the basic nature of peering agreements that make their entire business model viable.
