A federal judge yesterday dealt a potentially fatal blow to Vonage Holdings, the Internet-phone service that offers one of the few alternatives to traditional carriers, by ordering it to stop using a technology that connects its network to the public telephone system.
U.S. District Judge Claude Hilton approved the request by Verizon Communications for a permanent injunction two weeks after a jury in Alexandria found that three of its patents had been infringed by Vonage, including one for the technology allowing the Internet company's 2.2 million customers to call regular phones.
