Vonage, a US-based provider of digital phone services, has received approval by the US Patent and Trademark Office for an internally developed patent, called method and apparatus for enhanced internet telephony. The invention, which was filed for patent in 2003, is claimed to make it less likely for customers to encounter dropped calls, incomplete attempted calls or other communication problems resulting from typical router function and behavior.
According to the company, the new patent pertains to improvements in internet telephony where network address translation is required. The patent addresses the issue of a router losing an outbound port during an internet telephone connection. To avoid the router timing out and closing the outbound port, the patent causes the media terminal adapter to send an outbound message to the internet telephony regional data center.
Louis Mamakos, chief technology officer and executive vice president, said: This is an exciting moment for Vonage as we continue to have a good experience for our customers.
In July, 2008 Vonage announced the launch of Vonage Pro(SM), a digital voice offer featuring five innovative components that keep the user connected to home while on the go, including the ability for customers to use their home phone number anywhere they have access to an internet connection. Vonage Pro also includes Unlimited Vonage Residential Digital Voice service, 25 Vonage Visual Voicemail(R) messages, 25 411 Directory Assistance calls, and automatic integration of Vonage Contact Center.
