- If you think that VoIP E911 is "here," and that most of the problems
have been solved, you really need to read my
colleague Anne Broache’s piece entitled Net phone
providers describe E911 obstacles.
On the scene this week at a suburban D.C. conference sponsored by the National
Emergency Number Association, Anne points out
some of the real problems.
Start with something called the Master Street Address Guide, which is supposed
to store a 911 dialer’s location info.
The MSAG is only as intuitive as the information fed to it- information which
may or may not be reliable.
"Because in many cases it’s up to Net phone users to update that address," Anne
writes, it ‘can be whatever the subscriber believes their address to be, and
those of you who have been involved in 911 for a while know that’s not necessarily
an accurate’ descriptor, said Roger Hixson, NENA’s technical issues director.
Anne then adds her spot-on impression that Net phone providers, telecommunications
companies that own the 911 infrastructure, public safety operators and administrators,and
call-routing vendors aren’t exactly on the same page.
"There was really noguidance or guidelines given to us," she quotes Steve O’Conor
of the Brevard County, Fla. Board of Commissioners.
Readers, keep in mind that these obstacles exist when the user is in a fixed,
on-record location. You’ve already been reading my take on the illusion of nomadic
E911. But after reading this post, you may agree with me that when it comes to
even regular (i.e., non-nomadic) VoIP E911, we have a long way to go.
