cNet’s News.com reports that companies providing internet telephony will be required to set up their own 911 service centers, under a forthcoming FCC directive. Vonage, the nation’s biggest VoIP provider, has been accused of failing to notify customers about the limitations of its 911 service, which does not always provide a live operator. Under the FCC plan, Vonage and other providers would have to bring their service up to speed with the traditional phone system.
