[Asterisk-Users] Known SIP - NAT Solutions?

[Jon Pounder]

When situations like this arise all the time, why is there such a delay in 
getting ipv6 rolled out when it solves all these problems ?

I realize no one acting alone can roll it out in any sort of meaningful 
way, but the solution has already been around over 10 years, just not 
getting used.
