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.
