The work in ECRIT has certainly helped the state of deployed E911 over VoIP to be much better today than it was in say 2000. More importantly, the progress that the industry is making in various SDOs, including the IETF, has been the primary factor that has caused regulators to not pass some regulations over E911 and VoIP. In my opinion they type of regulations that would have been passed at this early stage would probably have been overall harmful. When you have a case like what happened in Canada where a child is dead and probably would be alive had a PSTN phone had been used instead of a VoIP phone, well it's not easy to convince regulators not to "Do something" about the problem. Obviously I think we ought to be doing something about better emergency calling but I believe a well thought out global industry based approach is superior to a knee jerk driven reaction done on a country by country basis.
