'Work' has some ongoing projects to add IPv6 support to some of our
VoIP products, but it is non-trivial and there is little commercial
pressure to complete it quickly.

Not the least of the issues is that it is much more difficult to write
a small trivial IPv6 implementation to run on an embedded system.
(The IPv4 implementation on the DSPs doing voice only needed to support
UDP, the hardware modifies the MAC address on inbound packets based
on the port numbers - everything else goes to a ppc using the same IP
address. The same tricks can't be used for IPv6.)
