[cisco-voip] 911 Calls

[Dennis Heim]

You safest bet is to utilizing an inter-digit (t.302 delay).

911 & 911?, so when you dial 911 it will wait to see if you are going to enter another digit. Also make sure urgent priority is not checked. That can help reduce accidental 911 calls.  I’d rather have false 911 calls then have my butt on the line for unity failing, etc.

I think you hit the nail on the head on two points:

 *   you have to be aware of the 911 legislation in your area
 *   how many "points of failure" are you adding
The list brings of many options and examples, you have to be aware of the ramifications of these examples and see if they fit.

I for one, would not want to introduce anything outside of the native phone system into 911 call handling. But that's just me....

Just out of curiosity, but what are the legal ramifications of this?

You are technically interfering with the routing of an emergency services request and could run into some pretty serious legal jeopardy (at minimum serious civil liability if Unity goes down....)

In IL the installer of the phone system is legally responsible for the routing of 911 calls (both the 911 and the X.911 pattern (X being the access code)....

We route to Unity first playing a message that says “you have dialed 911, if this is an emergency stay on the line, otherwise hang up”.  There are blogs out there how to do it, I can find it for you if you want to go this route.  9911 goes out normal.

All,

Lately we've been seeing more and more 911 calls go out of our building by "accident."  None of our route patterns have changed lately.  I'm not sure why this could be happening.  A couple of questions.

1. Is there a good way to prevent this from happening? Is anyone else doing anything special to prevent this?
2. I'm trying to find a way to report on the 911 calls and am unable to find a report that will accommodate my needs.  Does anyone know of reports to run for this?

Thanks,
Tim
