Over 90% of Vonage U.S. Subscriber Lines Now Have E911

HOLMDEL, N.J., Sept. 26 /PRNewswire-FirstCall/ -- Vonage America Inc., a subsidiary of Vonage Holdings Corp. (NYSE: VG) , a leading Internet telephony provider, today announced that over 90% 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.

In less than one month, Vonage has equipped an additional 250 locally-run emergency call centers across the U.S. with E911 -- bringing the total number of calling centers with emergency 911 service to over 5800.

Vonage's nomadic E911 solution gives customers the ability to reach a Public Safety Answering Point (PSAP), or 911 center, through the dedicated 911 network infrastructure. With Vonage's nomadic E911 solution, a customer's call is automatically routed to the appropriate 911 center, with the caller's registered street address and telephone number appearing on the dispatcher screen -- regardless of where or what exchange they are calling from. Vonage will continue to turn up and test new PSAPs that are VoIP-ready every day.

"Today over 90 percent of our U.S. subscriber lines have full E911 capability, which is a tremendous step for Vonage," said Vonage CEO Michael Snyder. "Vonage will continue to work with the FCC, regulators, Congress and public safety until PSAPs across the nation are equipped with E911."

In just 15 days, 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 5800.

* In the event Vonage is unable to connect to the 911 system or for customers who are using mobile devices such as Wi-Fi phones, softclients, or the Vonage V-Phone, Vonage offers a national emergency call center which enables customers to get local help when they need it.
