Depends on the codec. Yes, most people default to G.711, but
my experience with G.729 and header compression has been good,
and closer to 12Kbps.
I definitely agree that it's much more symmetrical than web
traffic, and could therefore mess with someone's capacity
planning. Denying traffic that doesn't conform to your engineering
is one response. Re-engineering is another. Do what you will
with your network, I know what I'd do with mine.
