The
OpenH323 project aims to create a full featured, interoperable, Open
Source implementation of the ITU-T
H.323 teleconferencing protocol that can be used by personal developers
and commercial users without charge.
OpenH323 development is
coordinated by Quicknet
Technologies Inc. but is open to any interested party. Commercial
and private use of the OpenH323 code, including use in commercial
products and resale, is encouraged through use of the MPL (Mozilla Public
license).

Getting Started
See the FAQ
for the aims and targets of this project and a general introduction.
Join the mailing
list, or download the code. If you want to
develop code with OpenH323, then read on how
to join the project, and what you will need. A public
CVS archive of all OpenH323 code is also available
Here is a list of people and companies who have
contributed resources and web space to OpenH323 as well as those
working on associated projects. If can think of anyone who should be be
listed here, please contact us at webmaster@openh323.org
We are compiling a list of
H.323 clients and other H.323 applications. Please e-mail
us if you have any additions or changes.
