I'm a frequent listener to the VUC conference on fridays and tomorrow is a show that will be on IPv6 so I thought you might be interested in hearing it. From their website announcement: Olle Johansson will be joining the VUC conference to describe the state of the migration to IP v6 in VoIP-dom. Olle (@oej) needs no introduction. His company, Edvina was founded in 1987. Since then, theyve promoted open standards, for networking, for application integration and for software. Olle is a pillar of our community and an outspoken critic of all that stands in the way of progress in his areas of expertise. Proposed Issues on the discussion agenda - IPv6 how to get it into your network today - VoIP and IPv6 why is this a good marriage? - Experiences from Asterisk 1.8 IPv6 support - Living in a dual stack world - Dual stack considered bad for VoIP? - Implementations out there a call for help? Which devices used in the VUC community supports IPv6? Any experiences? - Setting up a VUC IPv6 testbed - Follow-up call planning monitoring the IPv6 migration process in the VUC community.
