OpenH323

The OpenH323 project had as its goal the development of a full featured, open source (MPL) implementation of the H.323 Voice over IP protocol. The code was written in C++ and, through the development effort of numerous people around the world, supported a broad subset of the H.323 protocol. The software has since been integrated into a number of open source and commercial software products.

The project was forked into two new projects in October 2007. Each of these projects has a different focus:

• The Open Phone Abstraction Library (OPAL) project continued the architectural development of OpenH323 with the goal of integrating additional VoIP protocols such as SIP and IAX2 changing the API considerably.
• The H323Plus project continued the expansion of the support for H.323 as well as support for existing OpenH323 applications.
