That is a wierd story.
The call came into a 9-11 center in Houston from a surrounding county, but originated from somewhere in Afghanistan?
Something isnt right about that picture...911 automatically prints out the point of origin of every incoming call when the phone rings.
911 is a mapped number. The PSAP (police, sheriff, highway patrol) is programmed to match your phone number to the right agency. "under the covers" there is a standard directory number for the "911". If you call that standard directory number, the PSAP perceives a 911 call inbound. If it comes from out of the area, it can't map to a street address. The full phone number might well be displayed to the 911 operator.
The continuity of Caller ID is dependent on High tech phone systems. If a call goes through a lower tech...Old fashioned phone system then I don't think there would be any ID to the call...Then they would have to track it the old fashioned way...From point to point.
