Question : How do I determine who is dialing 911

I am running a Cisco VOIP phone system, two callmanagers, unity messaging, and IPCC. I am getting multiple daily call backs from 911 saying that we just dialed 911 and hung up. This is sometime reaching a volume of 10+ calls a day. Is there a way to report on this and determine which handset/directory number is dialing 911?

I have attempted using the CDR Analysis and Reporting tool but have not gotten the exact results I am looking for any help would be much appreciated. Also the ability to have an alert or notification setup anytime 911 is dilaed would be helpful.

Answer : How do I determine who is dialing 911

Benhar,

The CDR wasn't giving me all of the data beause of the following:
In Cisco Call Manager Administration, under ServiceService Parametersselect the Primary Server and the Cisco CallManager Service. Then find CDR Log Calls with Zero Duration Flag : this is by default set to FALSE, this means calls that are 1 second or less would not be logged IE 911 hang-ups. (you should repeat this for all of you CallManager Servers. This explains why my CDR Reports where not giving me all of the results I should have seen.
When you change this setting you must also restart the Cisco CDR Insert Service, this is done by going into the Cisco CallManager Serviceability website and under Tools--Control Center--Select the primary server, find the service mentioned above in the list, select its radio button and then restart.

Since the CDR reports are so limited in time duration compiling data for long periods was extremely time consuming so you can do the following, on the Primary CallManager, open Microsoft SQL server query analyzer, select the Primary CallManager, then the CDR Database from the drop down, then run the following query which will return only calls to 911:

select callingpartynumber,datetimeorigination from calldetailrecord where finalcalledpartynumber='911'

The query returns the timedateorigination value as an integer which represents Epoch time, to convert this you must use a converter I found one at http://www.epochconverter.com/# .

I hope this helps others.
