GNU Gatekeeper

GNU Gatekeeper

GNU Gatekeeper (GnuGk) is a feature-rich, open-source project that implements an H.323 gatekeeper.

A H.323 gatekeeper controls all H.323 clients (endpoints like MS Netmeeting) in his zone. Its most important function is address translation between symbolic alias addresses and IP addresses. This way you can call someone instead of knowing which IP address s/he currently works on. It is an integral part of most useful internet telephony installations that are based on the H.323 standard.

This software allows users, among other things, to register devices, make calls, perform AAA (Authentication, Authorization and Auditing), manage config at runtime and traverse NAT.
