even thousands of miles away from home, yet if the call goes to an answering point at all, it would be the one associated with the caller's address and not the actual location of the call. it may never be possible to reliably and accurately identify the location of a voip user, even if a gps receiver is installed in the voip adapter, since such phones are normally used indoors, and thus may be unable to get a signal. in march 2005, commercial internet telephony provider vonage was sued by the texas attorney general, who alleged that their website and other sales and service documentation did not make clear enough that vonage's provision of 9-1-1 service was not done traditionally. in may 2005, the fcc issued an order requiring voip providers to offer 9-1-1 service to all their subscribers within 120 days of the order being published. in canada, the federal regulators have required internet service providers (isps) to provide an equivalent service to the conventional psaps, but even these encounter problems with caller location, since their databases rely on company billing addresses. in may 2010, most voip users who dial 9-1-1 are connected to a call center owned by their telephone company, or contracted by them. the operators are most often not trained emergency service providers and are only there to do their best to connect the caller to the appropriate emergency service. if the call center can determine the location of the emergency they try to transfer the caller to the appropriate psap. most often the caller ends up being directed to a psap in the general area of the emergency. a 9-1-1 operator at that psap must then determine the location of the emergency. voip services operating in canada are required to provide 9-1-1 emergency service. in april 2008, an 18-month-old boy in calgary, alberta, died after a toronto voip provider's 9-1-1 operator had an ambulance dispatched to the address of the family's previous abode in mississauga, ontario. emergencies across jurisdictions when a caller dials 9-1-1, the call is routed to the local public safety answering point. however, if the caller is reporting an emergency in another jurisdiction, the dispatchers may or may not know how to contact the proper authorities. the publicly posted phone numbers for most police departments in the u.s. are non-emergency numbers that often specifically instruct callers to dial 9-1-1 in case of emergency, which does not resolve the issue for callers outside of the jurisdiction. nena has developed the north american 9-1-1 resource database which includes the national psap registry. psaps can query this database to obtain emergency contact information of a psap in another county or state when it receives a call involving another jurisdiction. online access to this database is provided at no charge for authorized local and state 9-1-1 authorities.
