[cisco-voip] 911 Calls

Hey Tim,

I think what you're looking for is in CUCM -> System -> Service
Parameters -> Your server -> Cisco CallManager

CDR Log Calls with Zero Duration Flag *

Hi Wes,

How would I set the above parameter to true?

Thanks,

Tim

That is possible.  All CDR's may not be logged.  By default:

CDR Logs calls with 0 duration is set to false.  This means that calls
that do not connect or calls that disconnect for normal reasons such as
a user hanging up will not be logged into CDR.  Any call that
disconnects with an abnormal cause code will be logged.  Keep in mind it
is 'connect' in CM's visibility.  On ISDN/PRI trunks CM has visibility
into answer supervision.  On analog trunks CM does not have any
visibility into answer supervision.

If a user dials 911 and hangs up before answer or immediately after
answer then the call will not be logged in CDR.  The only ways to
identify that call are (1) set the above parameter to true (2) review CM
SDI or SDL traces from the time of the incident.

Yea, I think I'll use UCCX instead.  It's HA and is rarely down for
anything, otherwise our business stops!

On another note, I've been looking frantically through my CDR reports
and I cannot find anywhere where 911 calls originated from our system.
Am I missing something here?  Does anyone have any direction as to what
report I should run and sort by?

I'm skeptical that someone else out there is masking 911 calls with our
numbers.

Any help is appreciated.

Thanks,

Tim

whatever your final solution make sure to document and share the
dependence among your organization.  In working with support teams I
experience first hand that most customers think nothing of rebooting
voicemail servers in the middle of the day.  If you finalize on using
Unity that would result in a 911 outage.

We frequently see tremendous dissatisfaction caused by differing service
level agreements or service level expectations between services and the
products or components delivering those services.

Yea, I sent it to HR and letting them sort it out :-)  All very good
ideas though.  Appreciate the feedback.

Instead of using the complicated Unity solution, think I'll leverage our
UCCX environment. Think it will be much easier.

Thanks again!

Agreed. I would also add that you should get executive approval as well
from someone in your organization who fully understands the
ramifications of what has been done.

In our instance, we had our Campus Community Police request/approve the
changes.

very creative solutions.  please consider checking with your local laws
as well.  some areas have laws that specifically prevent 911 intercept
and require it route immediately out to emergency services.

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
