I agree that country code plus number is the bare minimum, but I've only 
run into one carrier that refused to ("couldn't") do that.  Ironic 
because they also do international origination, so calls are delivered 
to us without any way to know if they are US area+number or country+number.

I've never run into an issue with the CID side of things.  I don't think 
it's that important, but maybe others do.  We just pass it along as it is.
