Question about propagation and queuing delays

Do carrier ISPs classify their voice traffic as Really

isn't just selfishness, since We All Know voice is less
tolerant of latency and jitter than TCP.

We do?

Try to keep a single-TCP-stream session over 500 mbit/sec of goodput
halfway across the country sometime. Most of us who have VoIP boxes
have 20ms or better jitter playout buffers. Ever (successfully) talk
to someone over a GSM handset when their coverage was a little
marginal? The human ear is a marvelous tool compared to a TCP timer.

Apologies if "We All Know" was supposed to be a cue to sarcasm or irony...
