"And there are other dirty tricks available to broadband ISPs. Telecom New Zealand, for example, is reportedly planning to alter TCP packet interleaving to discourage VoIP. By bunching all voice packets in the first half of each second, half a second of dead air would be added to every conversation, changing latency in a way that would drive grandmothers everywhere back to their old phone companies. This is because phone conversations happen effectively in real time and so are very sensitive to problems of latency. Where one-way video and audio can use buffering to overcome almost any interleaving issue, it is a deal-breaker for voice."
It's implied here that they identify the VOIP packets in order to bunch them. My VOIP tie line run across an encryted UDP VPN link so I can't see how they could affect just my VOIP traffic. Dave
