That's what I thought until we were involved with diagnosing a VoIP
problem on the east coast. The site had a dedicated DS3 with no other
data users. VoIP was choppy and not really usable, however a dsl connection
at the same site sounded good using the exact same equipment.

We found that someone had mucked with the network settings in XP turning
off the QoS support. After re-enabling only that single option and
retesting did the DS3 provide exceptionaly good quality.

Turned out that Worldcom had in fact enabled QoS (on at least a portion
of their backbone network) between the east coast and midwest. It impacted
both directions.  I was surprised, and I've been doing 100% corporate 
networking for 20+ years.
