Texas sues VoIP companyIt blocked 911 callsBy Nick Farrell: Wednesday 23 March 2005, 07:43A VOICE over IP outfit is being sued by the State of Texas for blocking access to emergency calls.Vonage has been sued, not for blocking the calls, but for failing to warn customers about limits to its 911 service. 911 is what the colonials dial to contact what in the UK we call 999 for.Texas Attorney General Greg Abbott said the state had taken action after a February incident in which a family with Vonage service couldn't get through to 911 dispatchers.A woman called Joyce John tried to dial 911 from a VoIP phone in her home after a burglar broke into the house and shot her parents.Her call was connected to an automatic recording saying she would have to dial 911 from a different phone because she had not paid for the service.Vonage considers that its 911 service is an add-on which customers have to pay more for. It says that it did nothing wrong as it did warn customers that they had to pay extra.It told PC World that VoIP 911 services don’t work the same way as traditional 911 service as dispatch centres can't pinpoint the address where a VoIP call originates.Surely they know the IP address and where that is situated?
