Hi Terry,<br><br>Can you get call detail records from callmanager for those 911 calls? one of the fields in each record is the device name of the originating device, should be straight forward then to trace back to whatever IP Phone(s) made those 911 calls.
<br><br>I've found on the couple times we've had complaints from our PSAP that after going back to the user you can actually see in their placed call log on the phone where they called 911, hung up, and then dialed another number that starts out similar. Might be easy to make an educated guess as to if it was a prank call or a mistake by doing that.

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Over the past 90 days one of our CCM installation sites has
generated more than 15 unintended 911 calls. (TAC call initiated and
their studying it)</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">In discussing this situation with the 911 call center their
previous historical experience in similar situations indicates that our cause
is probably a procedural/configuration problem rather than prank calls. For
example, we dial "9" for outside calls, and our geographic location
is adjacent to an area code that begins with 91X.</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">However, the installation is in a middle school and the
principal believes these are prank calls.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">My question is, what tools are available to help us
determine exactly what's going on here. The number the 911 call
center gets is always the same main pilot number at the front switchboard.
We have confirmed that on one occasion, this did happen at the front
switchboard but, there are at least 14 more instances when we know that
particular phone did NOT make a 911 call.</span></font></p>
