You are turning ON IPv6.  You are not turning OFF IPv4.   Turning
on IPv6 has no impact on IPv4 only equipment.   You can continue
to use the VoIP hardware in house for the next 20 years.   If you
are using VoIP hardware to talk to the rest of the world CGN's are
going to make a big mess for you.

And you can run that IPv4 cloud over 4in4 tunnels or 4in6 tunnels.
When CGNs start being deployed you will want to use the 4in6 tunnels
as establishing the 4in4 tunnel will be a pain and may not work.
