IPv6 is being introduced in part to solve the looming problem of a shortage of IPv4 addresses. Network address translation (NAT) widely used today will no longer be required under IPv6. Work is already underway in Australia to gear up for its widespread deployment.
According to Marc Blanchet, president of Viagenie. "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 auto configuration of VoIPv6 phones."
IPv6 Forum president, Latif Ladid, said: "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
Jason Fischl, CTO of CounterPath, claimed that: 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.
