Vonage America Inc., a subsidiary of Vonage Holdings Corp., a leading Internet telephony provider, announced that its subscribers in Contra Costa County, Ca., are now equipped with Enhanced 911 (E911) -- a feature that automatically associates a physical address with the calling party's telephone number.

In addition to Contra Costa, which includes key San Francisco Bay Area based cities, such as Mountain View, Concord, San Ramon and Walnut Creek, Vonage recently turned up E911 at more than 400 local run emergency call centers across the U.S. in less than three months -- bringing the total percentage of Vonage U.S. subscriber lines that have E911 to over 84 percent.

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.

"Turning up Contra Costa County is a great step for Vonage, as those individuals who have subscribed to Vonage's flat-rate, feature-rich calling plans in one of our Nation's tech hubs, will now have full E911 capability," said Jeffrey A. Citron, chairman and chief strategist of Vonage Holdings Corp. "In just three months, Vonage was able to equip over 400 more locally run calling centers with E911. Vonage will continue to work with the FCC, regulators, Congress and public safety until PSAPs across the nation are equipped with E911."
