LUXEMBOURG, MIAMI, QUEBEC CITY, VANCOUVER, March 8 /PRNewswire-FirstCall/ -- The IPv6 Forum, along with Viagenie, Stealth Communications and CounterPath Solutions, today announced that a series of successful VoIP calls over IPv6 has been carried out, marking an important advancement in worldwide interoperability among VoIP technologies using IPv6.

The VoIP calls, connecting Viagenie in Canada and Consulintel in Spain, were conducted using the CounterPath eyeBeam(TM) softphone through the IPv6 version of Asterisk(R), ported by Viagenie, a consulting and R&D firm in advanced IP networking. The Asterisk-IPv6 server was located on Stealth Communications' Voice Peering Fabric (VPF) network.

Asterisk is the most popular and extensible open source telephone system in the world, offering flexibility, functionality and features not available in advanced, high-end (high-cost) proprietary business systems. Asterisk is a complete IP PBX (private branch exchange) for businesses, and can be downloaded for free.

"Asterisk-IPv6 shows the power of VoIPv6 by avoiding all issues regarding NAT traversal when using IPv4. The presence of NAT for VoIPv4 results in users issues, such as non-connecting calls, one-way audio, non-working DTMF. Asterisk-IPv6 solves all these issues and also brings, together with IPv6, true IP mobility, security and autoconfiguration of VoIPv6 phones," states Marc Blanchet, President of Viagenie.

"The IPv6 Forum and its IPv6 Ready Program are adding SIP into its test suite to promote SIP and IPv6 interoperability worldwide. This is another major milestone in demonstrating true end to end services," stresses Latif Ladid, IPv6 Forum President.

"EyeBeam implements the ICE standard from the IETF, providing a migration path from IPv4 to IPv6 networks. This series of calls demonstrates a successful test of IPv6 in a real network and represents an important step toward the widespread deployment of IPv6 technology," said Jason Fischl, CTO of CounterPath.

"The Voice Peering Fabric ENUM Registry and SRV Registry are fully IPv6 enabled. These registries map telephone numbers to Internet addresses, enabling companies globally to route VoIP phone calls among one another in a peer-to-peer fashion without touching the public telephony networks," said Shrihari Pandit, President & CEO of Stealth Communications. VPF is a distributed Ethernet network that functions as an exchange or meet-point for organizations around the world, carrying over one-hundred billion minutes annually.
