Vonage Says VoIP Traffic Blocked By Providers

Anonymouse writes "Advanced IP Pipeline reports that Vonage has filed numerous complaints with the FCC over their VoIP traffic being blocked by major providers, something providers have long worried about but had not yet been seen 'in the wild.' Analysts expect the issue of network neutrality (or network discrimination) is only going to get larger as the bell and cable companies expand their VoIP efforts and bump heads with smaller providers."

      Not only does it apply to POTS, it applies to any situation where someone/thing is carrying goods or information for hire. The Post Office, couriers, and ISPs are all examples of common carriers. In a regulatory view, Common Carrier status protects a carrier from legal liability for what it transports, however, such a carrier can't then cherry-pick what it wants to carry. See Wikipedia.

      Now, IMHO, this is why the big carriers can't or won't filter competing VoIP traffic. No doubt they'd love to, but then they wouldn't be able to use Common Carrier status as a legal protection against what goes on through their network. No doubt the RIAA would love to be able to force Comcast or AT&T to filter music sharing.

I did a traceroute to other servers in what I thought would be a similar geographic location and got far fewer hops. This isn't proof of any messing with packets by Verizon but it sure did make me suspicious because the latency to vonage servers was much higher than the latency to other websites.
