[Asterisk-Users] 911 Options

[Ira Burton]

I am curious if anybody has pointers on the best way to get the 7
digit PSAP number for an area.  I am thinking about making a '911'
extension that will dial the PSAP number, wait for the PSAP to answer
and play a message giving the address of the originating call, and 
replay the the information every three minutes.  I am concerned what
may happen if my children try to dial 911 in an emergency but do not
yet know our address.

How are other people handling this?
