As has been noted in a couple of recent articles, "11" is reserved for
certain custom calling features from pulse-dial phones.  For example,
I can dial 70* to cancel call waiting, or I can dial 1170.  This
scheme is in wide use across much of the country.

The one thing I would've changed is that it seems logical to me to
say, "Dial 01 for international, and then 1 if it's direct-dial or 0
for operator assistance," to make it more analogous to domestic calls.
Thus we would have 011/010 instead of 011/01.
