OpenH323

From Wikipedia, the free encyclopedia

The OpenH323 project goal is developing a full featured, open source (MPL) implementation of the H.323 Voice over IP protocol. The code is written in C++ and, through the development effort of numerous people around the world, fully supports the H.323 protocol. The software has been integrated into a number of open source and commercial software products.

[edit] The implementation of VoIP protocols:

PWLib - a multi-platform C++ class library. Programs based on PWLib can run on both Microsoft Widows and Unix/Linux. The library contains both the “basic” classes (strings, arrays, lists) and the higher-level functionality (networking, multi-threading).
OpenH323 – a library for the development of H.323 applications. It uses PWLib for platform independence. The library has its own ASN.1 parser that generates the classes for encoding and decoding of the protocol messages used in H.323.

[edit] Sample network phones implementations:

OhPhone: Command-line phone
OpenPhone: GUI for OpenH323

The openh323.org web site contains out-of-date information and a very old version of the code (see http://www.voxgratia.org/docs/faq.html#1_4 for more information). New releases can be found at http://www.voxgratia.org/.
