Vonage America Inc., a subsidiary of Vonage Holdings Corp., a leading Internet telephony provider, announced that over 80 percent of its U.S. subscriber lines now have Enhanced 911 (E911) service -- a feature that automatically associates a physical address with the calling party's telephone number -- and that it is continuing to quickly equip new counties across the nation with E911 everyday.

Over the past two weeks, Vonage has equipped an additional 85 locally-run emergency call centers, in over 30 new counties, with E911 -- bringing the total number of calling centers with emergency 911 service to over 4700.

In June 2005, 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 80 percent of our U.S. subscriber lines have full E911 capability," 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 May 12, Vonage has added the following counties to its list of those with E911 capabilities -- bringing the total number of calling centers with emergency 911 service to over 4700.
