Ouch. Also in the US, E911, the requirement and system to locate mobile callers, appears to be haphazardly deployed and under tested. A few years back, I had to call emergency services from Vacaville, CA and the Solano County dispatch was unable to determine my location. I followed up with Verizon corporate, who checked that their systems were correctly configured to talk to Solano County's E911 system. My assumption is there is no E911 state/federal auditing or testing compliance to assure all 911 centers are properly configured for all carriers.
