Many networks are migrating from IPv4 to IPv6. What can you do if still have H.323 endpoints that only support IPv4 ?

The GNU Gatekeeper can translate IPv4 into IPv6 calls and vice versa.
You can use one GnuGk to IPv6 enable all of your existing IPv4 endpoints.

All you have to do is enable IPv6 in your configuration and GnuGk will automatically
detect the connection type of your endpoints and convert the call.

All it takes is one switch in your config:

[Gatekeeper::Main]
EnableIPv6=1 

This report considers the transition from IPv4 to IPv6 alongside the use of network technologies to prolong IPv4 use in the face of depletion of further IPv4 protocol addresses.
