I hear this statement constantly from people with experience in
circuit-switched telephony, and I'm curious where the data is to back it up.

In Japan, about 10% of the fixed wireless telephony customers use Internet
telephony and, to my knowledge, none of the DSL or FTH providers there are
using QoS. In the US, AT&T, Sprint, and other fixed line carriers, along
with startups like Vonage are offering Internet telephony and they don't
require QoS in order for you to get the service (and no DSL provider offers
QoS, to my knowledge). If QoS is so necessary for real time services over
the Internet, then maybe you can explain to my why all these customers are
buying the service (and the companies involved are presumably making money)
without it?

A possible counter example, CableLabs ,deploys some kind of RSVP QoS on
their IP over cable, but I am not sure how it is used and I don't believe it
is required for VoIP.
