[cisco-voip] 91 possibly calling 911?

[Kent Roberts]

We addressed this doing 2 things.  1 make all fax and modems unable to dial
911.  (solved 50% right off the bat).   Then we setup 911 to play a quick
"you have dialed 911 if this is an emergency stay on the line" and off
route.  9911 is immediate.   This solved 99.99% of all our accidental 911
issues.  Its amazing what a 4-6 second message saying you dialed 911 will do
to keep the local police happy.

just a though...
