OpenH323 Gatekeeper includes Radius and database support and many VOIP routing functions.

OpenH323 Gatekeeper forms the basis for a free IP telephony system (VOIP).The GNU Gatekeeper is very stable and it is being used commercially by many organizations to provide VOIP services.

Here are some key features of "OpenH323 Gatekeeper":

· executables for Mac OS X, Linux, Windows, FreeBSD and Solaris
· can be run as a Windows service
· accounting and call authorization via SQL database, Radius, file or external application
· flexible call routing
· number rewriting (calling and called)
· support for NAT traversal
· 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
