HOLMDEL, N.J., Aug 21, 2006 /PRNewswire via COMTEX News Network/ -- Vonage America Inc., a subsidiary of Vonage Holdings Corp., (NYSE: VG), a leading Internet telephony provider, today announced that over 85% of its U.S. subscriber lines are now equipped with Enhanced 911 (E911) service -- a feature that automatically associates a physical address with the calling party's telephone number.

Over the past three months, Vonage has equipped more than 500 locally-run emergency call centers across the U.S. with E911 -- bringing the total number of calling centers with emergency 911 service to over 5400.

In June, the FCC gave Vonage, and all Internet-based phone service companies, 120 days to create an E911 system from scratch, and provide all of its customers, wherever they are in the U.S., with E911 service. In that amount of time, Vonage worked closely with local 911 centers, also known as Public Safety Answering Points (PSAPs), across the country to turn on E911 for as many customers as it could. Currently, Vonage continues to test and turn up new PSAPs which are VoIP-ready every day and will continue to do so until Vonage customers have access to E911.

"Today over 85 percent of our U.S. subscriber lines have full E911 capability, which is a tremendous step for Vonage," said Jeffrey A. Citron, Vonage's chairman and chief strategist. "Vonage will continue to work with the FCC, regulators, Congress and public safety until PSAPs across the nation are equipped with E911."

Since August 7, Vonage has added numerous counties to its list of those with E911 capabilities -. bringing the total number of calling centers with emergency 911 service to over 5400.
