This is a really difficult issue.
And how.
How does this interact with phones whose What, like a party line? access (telephone) number is non-unique? Could where I am calling from be divorced If the standard of COM from what instrument I am using to call? is uniform, yes. Is there a parallel between smearing the signal over a spectrum of radio frequencies Radio frequencies are and smearing the identifying information a physical representation over a spectrum of numbers? Could calls of numbers...YES. to 911 carry no phone number but just "here I am" information -- a panic button They could, and what if function, in other words? you hang-up in distress.
I imagine I sound like someone calling in There are no experts here. to an ASK THE EXPERTS radio show... They don't broadcast.
