[cisco-voip] Tracking Down 911 Calls

[Ed Leatherman]

Hi Terry,

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.

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.
