OpenH323 Gatekeeper - The GNU Gatekeeper
The GNU Gatekeeper (GnuGk) is a full featured H.323 gatekeeper,
available freely under GPL license.
It forms the basis for a free IP telephony (VOIP) or video conferencing system.
Please read the manual (especially the tutorial) and the FAQ for general information
what a gatekeeper does or take a look at some
VOIP and H.323 books to get into the subject.

It is being used commercially by many organizations to provide VOIP or conferencing services.
we provide executables for Linux, Windows, MacOS X, Solaris, FreeBSD, OpenBSD and NetBSD
can run as a Windows service

database drivers for ODBC, MySQL, PostgreSQL, SQLite and Firebird
flexible call routing
number rewriting (calling and called)
support for NAT traversal (H.460.18/H.460.19, H.460.23/H.460.24 or own method)
full H.323 proxy
TCP interface to applications
CTI functions (eg. VOIP call-center, call transfers)
gatekeeper clustering support (neighbors, parent/child, alternates)
H.235 security
graphical user interface
it's free, including source code
There are also lots of ideas for new features.
