Almost every SMB network has ipv6 active on their network. They just don't realise it yet. Android, iOS, Windows Vista +, Mac OSX etc. Are all chattering away to each other over Link Local scope ipv6.

My last employer was amongst other things was a hosted PBX provider. As part of our normal run of the mill maintenance of the network we managed to ipv6 enable our core, client VRFs and Voice servers (Freeswitch rocks), we even got a snom handset to make a call over ipv6. The only thing stopping us from going to full production with the handsets in that mode was remotely restoring config onto it was only possible over ipv4.

However when a handset comes along that will work that way, everything will be ready. If you want to try SIP over ipv6 send an invite to sip.itslenny.com, Lenny will happily chat to you for hours over either ipv4 or ipv6.

Why not bother, hop in the water is fine. I've been swimming in ipv6 for years. Honestly you have spent more time bitching about ipv6, that it would take to actually just do it.

This is starting to remind me of the conversations I have with my children over homework...
