HOLMDEL, N.J., July 9, 2013 /PRNewswire/ --Vonage Holdings Corp. (NYSE: VG),
a leading provider of communication services connecting people through
cloud-connected devices worldwide, today announced that it has been granted
two new patents by the United States Patent and Trademark Office: U.S. Pat.
No. 8,483,210, "Method and Apparatus for Voice Traffic Management in a Data
Network," and U.S. Pat. No. 8,478,548, "Apparatus and Method for Automated
Inventory Tracking and Authentication."

The '210 patent, issued today, relates to a device that transmits both voice
and non-voice communications such as a VoIP (Voice-over-Internet Protocol)
telephone adapter. The patented technology maintains the voice quality on
calls by automatically adjusting the device's bandwidth.

"This invention ensures that call quality remains high in situations where it
could be otherwise compromised, including when the internet connection used
for making VoIP calls is also used for other purposes, for example,
downloading large files," said Chief Legal Officer Kurt M. Rogers.

The '548 patent, issued on July 2, relates to technology that allows network
operators to verify that devices connected to their networks, such as VoIP
telephone adapters, were distributed through authorized channels.

Vonage has been granted nine patents so far in 2013. The company now has 27
U.S. patents and nearly 180 U.S. patent applications pending, along with many
foreign patents and pending applications in jurisdictions worldwide.
