GNU Gatekeeper 4.0 available

I am pleased to announce the release of GNU Gatekeeper 4.0.

It is now available from http://www.gnugk.org/h323download.html.

This release includes source code suitable for Linux, Windows, MacOS X,
FreeBSD, NetBSD, OpenBSD and Solaris and executables for Linux.

GnuGk 4.0 includes many new features as well as some important bug
fixes, but remains fully compatible with your previous configuration
files.

Whats new ?
  • rewrite of the H.235 password authentication - much better interoperability and much more secure (it is high time to get ride of MD5 based authentication!)
  • IP authentication for all RAS and Q.931 messages
  • important IPv6 updates and fixes
  • support for TCS0 call transfers ("reroute") that can be initiated from applications
  • better NAT traversal support for unregistered endpoints
  • better blocking of spam calls using SQLAuth
  • per endpoint codec filtering
  • DisplayIE rewriting
  • more secure handling of status port passwords (only hash stored)
  • important fix for ODBC database driver
  • CalledPartyNumber IE rewriting for better Polycom interoperability
  • bug fixes

Some of the new 4.0 features are discussed in more detail this post:
