Sure, but NAT64 doesn't let SIP phones on an IPv6-only network talk to SIP phones on an IP4-only network.


Right, that is why we have SBC / b2bue for the cases we want to work.


Ok, so you concede that NAT64 requires yet another device at the edge to make the SIP phones work...


We have agreed to disagree on the value of this before.  Sorry your not so popular protocol is going the way of EGP 
.... it's just not fit for the evolving internet and will be subject to natural deselction. I am sure you will 
disagree with that and insist every end user must always support ipv4 because rtmfp is top of mind for so many users 
.... but we can leave it at that ....please



...and we'll agree to disagree on this one (RTMFP)... and users will just be ok with BitTorrent and Skype not working 
on the v6-only + NAT64 networks you're building, I suppose?

Uh, BitTorrent works just fine for me on IPv6.
