OVERVIEW
The "asterisk-oh323" package adds H.323 support to the
ASTERISK
soft PBX. This is
achieved by interfacing the OpenH323 library
to ASTERISK through an appropriate channel driver (loadable ASTERISK module).
The package provides the channel driver as well as a wrapper,
in a shared library form, which incarnates the bridge between the C++
implementation of the OpenH323 library and the C implemented ASTERISK.
This software is still under development and improvement towards a stable
and full featured software, but it works without many problems.
In the current state asterisk-oh323 is able to initiate/receive calls
to/from H.323 endpoints. It has been successfully tested with all the H.323
terminals offered by the OpenH323 site (ohphone, openphone), Gnomemeeting,
Microsoft Netmeeting, various Cisco routers, Snom phones and many software H.323 IP phones.
Part of this work was supported by the IST-2001-34447 AVPACK EU R&D Project.

DOWNLOADS
From here you can download
the latest version for Asterisk STABLE and
the latest version for Asterisk HEAD
(all versions are available here).
The package requires the PWLib and OpenH323 libraries
from the OpenH323 site (see Links).
Detailed instructions on how to build this package and how to
use it, can be found in the included README file.
Local copies of the OpenH323/PWLib libraries that we have used for the
development of the software can be downloaded from here.
We recommend to download and install these libraries.
Also, various Asterisk-related utilities can be found
here.
Please use the bugtracker to report discovered bugs,
to request features or
contribute patches and/or documentation.
