James kindly set them up, checked they registered, and could at least try and make a call (no audio it seems), so I had a good starting point. He even gave me detailed notes, put the IPs in forward and reverse DNS and put labels on the phone for me. Pretty much exactly everything I could want.
Sadly not working, so I go to check the IP they actually have.
So I go in to the phone menu to check the IP setting. That screen says my IP is
[20, 0, 0, 0
Which is not that helpful.
Sadly they are not registering, not pinging and just basically not working at all.
[Yes, I have tried turning it off and back on again!]
Sounds like back to the drawing board already.
This display issue does rather highlight that issues with IPv6 are not really going to be that technical. I bet there are loads of niggles like this, somewhat like Y2K, which will be easily fixed when people find them, but just have not been through about.
And yes, I know snom are way behind on IPv6, but we have lots of people with Snoms, and they are generally quite nice phones, so trying to get the buggers working.
