What is the PROPER public safety agency for mobile phones? Enhanced 911 was recently installed in Phoenix, and we discovered that when we called it from our Ham Radio Autopatch system, the operators sometimes would not believe us because we reported incidents 20 miles from the "originating address"! With the increased sales of cellular phones, this problem will increase. The solution used in Phoenix is to program those numbers into the system so that they show up as "mobile", and to route them to the county sherrif's office rather than the jurisdiction of the "originating address". Another problem is that 911 operators often read back the number calling. Our autopatch numbers are secret to prevent people from dialing them and tying up the system.
