Possibly. The ones with withheld caller ID first get the 'line not in

Is that wise? I know hospitals, police etc should be able to present
a number but I bet a significant number don't...


Precisely the problem that we perceive. We *know* some bona fide
NHS-source calls appear without a presentation number (whether it says
withheld or just announces external call I cannot now be sure). And we
really don't want to miss them.

And on this general theme, how do you stop spam SMS?
