H.323 Video Conferencing with GNU Gatekeeper has been improved with the new released announced by Jan Willamowius, Founder of the GNU Gatekeeper Project.

A new major release of the GNu Gatekeeper has been anounced. This new version “has many new features that will allow even your legacy endpoints to move to a new age of H.323 audio and video communications.”

New features:
– full traversal zone support (gatekeeper-to-gatekeeper H.460.18/.19)
Now you can place one GnuGk behind a firewall and let it tunnel out the calls for all other devices behind the firewall eg. to a VCS or to another GnuGk.
This was probably the most request feature in the past.

– full IPv6 support (incl. IPv4-IPv6 proxying)
With the proxy function, you can let GnuGk manage a network of IPv6 endpoints and connect them to the IPv4 network or make legacy endpoints reachable for IPv6 calls.

– RTP multiplexing (all calls to and from devices supporting H.460.19 will only use 2 sockets total)

– rewrite destination IPs into aliases

– ENUM, SRV and RDS routing policies extended for LRQs, in case the calling gatekeeper isn’t able to do this

– notifications when GnuGk opens listen ports
This allows you to update firewall rules on the fly, so you only have the minimum amount of ports open.

– improved H.235 password authentication with neighbors

– massive performance improvement when (re-)loading large numbers of GW rewrites

– interop fixes for Polycom m100 and Sorenson endpoints

– fixes in the underlying libraries so *BSD systems can get the latest GnuGk features

– a few bug fixes

The project provides executables for Linux (32 and 64 bit), Windows, MacOS X, FreeBSD, OpenBSD, NetBSD and Solaris.
