Thus spake "Jay R. Ashworth" <jra@baylink.com>
How about an anycast address implement(ed|able) by every network provider that would return a zipcode?
First, there are plenty of examples of ZIP codes which are shared by multiple municipalities and thus PSAPs, but at least you'd get _someone_ who could probably help, even if they needed to transfer you to a different PSAP (assuming that's possible). Cell phones have the same problem when you're near city or county boundaries. Second, there are at least two states where you must provide location information _within X sqft_ to the PSAP. In the business world this means you need to know which part of which floor in which building the phone is located, ostensibly so the police/fire crews don't waste time searching for you if you're unable to speak. This is a nightmare for PBX admins, VoIP or not. S Stephen Sprunk "Those people who think they know everything CCIE #3723 are a great annoyance to those of us who do." K5SSS --Isaac Asimov
