IPv6
giqcass:
I don't know the details but Google is a big supporter of IPV6 so you can bet they support it. Windows has supported IPV6 since at least Vista but if any piece of hardware doesn't support it then you are stuck with IPV4 without a tunnel. So I don't believe the fact that the SIP spec supports IPV6 means our OBis do. If the Obi can't connect to an IPV6 address then it will still use IPV4 addressing for any protocol. At some point that could be translated to IPV6 before it reaches it's destination but that isn't the same as IPV6 support.
I consider the fact that OBI has not weighed in on this in any fashion to mean they don't support IPV6.
Shameless:
IPV6 has been in the SIP spec for a long time. I would be surprised if OBI doesn't handle it. But then does your router or modem or ISP all handle it, doubtful. So I suggest you don't worry about it for now.

I looked through everything just to end this debate. I'm on the pre-release firmware. The Obi does not have a setting for a default IPV6 gateway. That means it can't even make the first hop over IPV6. That means it cant do IPV6 period.
By the way my router and modem absolutely support IPV6. I made sure before I bought them.
Shameless:
Just to straighten things out a bit.
All SIP resolver software is supposed to do a DNS quiry for the ip address. If the resolver gets back an A record it is supposed to use the IP address from the A record, which is an IPV4 address. If it gets an AAAA record it is supposed to use the IPV6 address in the AAAA record. In this way the phone should handle both IPV4 and IPV6 records at the same time seamlessly, depending on what it gets back from the DNS quiry. Well, at least it's supposed to. This would mean that if you set up your own DNS server it will work either way. SIP standards are quite clear on this.

I'm 100% certain an Obi202 and 110 do not do IPv6. Why/How? No mention of IPv6 in any of the manuals, or in any of the configuration interfaces. And in case they just 'left it out,' I've been watching the Google feature (bottom of Gmail details > Activity on this account) that lists current past account connection activity. And all mine are IPv6 except what I determined -- via process of elimination - are the Obi connections.
A few weeks ago I learned Comcast has enabled IPv6 in my area, in so called dual stack mode (meaning IPv4 and IPv6 work natively on the same network, no 4x6 tunnels, no ISATAP). I spend a few hours figuring out how to configure the router for this (key point: stateless prefix delegation), and it all started working. Now any IPv6 capable adapter on any host on the home network gets it's own (actually multiple) IPv6 address and the individual application chooses which protocol to use.
I can confirm Google and almost all it's products seamlessly use IPv6, this includes GV, Gmail, search, YouTube, etc. Firefox and Chrome both have a nice simple add on that shows which protocol is used on any Web page.
It's a somewhat satisfying feeling seeing this work and knowing one is out ahead of the curve on it. I suppose that is a little bit of chest thumping.
