First of New Calling Applications Now Available -Vonage Mobile Provides International Calling at Low Rates through Wi-Fi and Cell

Today Vonage (NYSE: VG) launched Vonage Mobile, its first mobile calling application for smartphones. Vonage Mobile is a free downloadable application (app) that provides seamless, low-cost international calling while on Wi-Fi or cellular networks*. Once downloaded, the service saves customers more than 50% on calls to dozens of countries versus the rates charged by wireless carriers while providing far more convenience than calling cards. Vonage Mobile will be available for download on the iPhone®, BlackBerry® and iPod touch® at www.vonage.com and the iTunes App Store later today.

With Vonage Mobile you can call around the world from home, a Wi-Fi hotspot, or while traveling around the country. Vonage Mobile is easy to use. There are no access numbers or new phone numbers to give to friends and family.

Simply enter an international number or select a contact from the existing contacts on your iPhone or Blackberry and hit send. Vonage does the rest.

This app will give customers exceptional per-minute rates to any country they want to dial. In the fourth quarter 2009, we will enhance the app to include the popular Vonage World plan that was introduced for home service in August. This enhancement extends the ability to make unlimited calls to over 60 countries for one flat monthly fee to mobile users, giving customers the choice to pick the plan that fits them best.

"Our new mobile app is an important step in establishing Vonage as a software technology company that enables high-quality voice and messaging across any device in any location, providing great value over any broadband network," said Marc Lefar, CEO of Vonage.
