I don't know for sure, but suspect that dialing "O" would get you
through to the "operator" the way it does by pressing "O" with such
systems (most are set up to reach some default number on that keypress).

Yes.

Also I think with enough practice, one can learn to make touch-tone
sounds with one's mouth. I think there was a guy on tv who could do
that.

OT I get few junk phone calls now, but with one, I pressed 9, and a
recording said something like, "You have been placed on our
do-not-call list".

Which is their list of confirmed phone numbers to harass next.
