[asterisk-users] IPv6 support?
Hey, Just wondering if anyone can let me know what the status of IPv6 support for Asterisk is currently. I see that the branch where development was happening has gone away. I was trying: http://svn.digium.com/svn/asterisk/team/blanchet/v6 Has this branched moved to somewhere else?

There is no real design issue with IPV6. No more NAT, that's all. However, network connections and DNS lookup stuff has to be IPV6 aware, as well as configuration parsing (wherever IP adresses may be expected). There might then be possible to use some IPV6 specific stuff, but it's quite far away. Note that some time in the future I could be interested in it. Our network is almost fully IPV6 enabled, and we have full, native IPV6 peering. -- Nicolas Bougues Axialys Interactive ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

No more NAT, that's all. Oh, there is a lot of design issues if you consider a dual-IP network. * If you dial me from an IPv4 network and I'm on IPv6, we have to force media proxy (Like NAT today) * If you're on a IPv4 only network, dialling me and get an IPv6 address to my SIP proxy - what do you do? * If you're dialing through a SIp proxy and your SDP is IPv6 and your SIP contact is IPv4, what do we do? ...I'm just shooting from my hip, but IPv4-IPv6 together *will* cause a lot of NAT-like situations. And it will take quite a long time before anyone has an IPv6 only situation ;-) I agree, IPv6 only is quite simple, but even if that's the case, there's a lot of code changes. IP addresses are everywhere in the SIP channel... /Olle ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

Well, usually right now : - machines have both v4 and v6 stacks - machines have both v4 and v6 addresses In this setup, there wouldn't be any change for v4 stuff. And v6 stuff is not much more complicated (although there still might be problems, like, for instance, some VoIP protocol having syntax problems with v6 addresses). The idea of a v4 client and v6 server (or proxy, or whatever) looks a little bit odd to me. If such a thing was easy to do, the world would have embraced ipv6 quite some time ago. IPv4 machines can only talk to IPv4. IPv6 maps IPv4 addresses. So a machine with an IPv6 only stack could theoritically reach a v4 client through some gateway. And I agree, this would be quite a mess from the voip protocol stand point.

AW: [Asterisk-Users] IPv6 support
In the setup I'm looking now there are IPv4-only and IPv6-only SIP-clients (or UA's) but the Proxies (or servers) are v4 and v6 dual-stacked (to make things a bit easier). I think there will be a lot of IPv6-only SIP-clients (e.g. mobile clients and all the existing IPv4-NAT'ed networks) and a lot of IPv4-only old legacy SIP-clients. We have to find ways to deal with such setups. There are ways with IPv4/IPv6 NAT-PT but I think this is not the right way (a lot of DNS-problems). There seems to be a way with RTP-Proxies (thanks Olle for the link) but even this (if it works) seems not the right solution for the problem (it's still a kind of NAT who breaks the end-to-end idea). What do you think about a back-to-back-server between the IPv4 and the IPv6 world?

What do you think about a back-to-back-server between the IPv4 and the IPv6 world? IPv6-enabled Asterisk fits right in. I think the missing piece is how IPv4 clients now when to use a proxy or not. But with Asterisk, you can (like NAT today) force the media stream through Asterisk and let asterisk make the decision if it's possible to let the media stream bypass (SIP re-invite) asterisk. Also, you could configure this is SER, so SER forwards calls from mixed networks to ASterisk. Again, I would like to see someone looking into what it takes to IPv6 enable asterisk, both coding (making sure we have space for 128 bits IP address and mask) and configuration, (accepting IP addresses with : instead of . ). /O ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
