This siproxd release introduces dynamically loadable plug-ins. The API consists of 3 mandatory functions that a plug-in has to implement. A plugin can take control at every important point of the processing. Siproxd now builds with libosip2-3.1.x - some function names have been renamed.

Libosip2-3.1.x contains some changes in function names (MD5 related functions). This causes siproxd-0.7.0 compilation to fail. The next release of siproxd will include detection of what set of MD5 functions is present and compile properly again. Meanwhile please use the latest siproxd snapshot or a version of libosip2 that is pre 3.1.

Anyone familiar with CYGWIN, GNU libltdl (dlopen wrapper for GNU libtool) and willing to donate some hours to the community, listen up. I'm looking for someone that would like to investigate (and get working) the new Plugin API with CYGWIN environment. Please contact me via my Sourceforge mail account (can also be just a patch and explanation what I did wrong in my ignorance to the "other" OS).

Siproxd will get a new plugin API. Plugins will be dynamic loadable libraries that are loaded during runtime. What plugins are loaded and the load order are given in the siproxd configuration file. This will make it easier for those of you that want to add new functionality to siproxd. So go ahead and have a look at it (check the current snapshot).
Your imagination is the limit. Register SIP call records in a database, a simple costing/billing plugin, CID masquerading - just to mention a few ideas.

Minor changes and some fixes are included in the 0.6.1 release.

Note: This is the last release supporting libosip2-2.x.x.

With the next release of siproxd (0.7.0) we will switch to the new version 3 of libosip2. Siproxd 0.7.0 is functionally equivalent to 0.6.1 with the only difference of using the new libosip2 version.

If you can, upgrade directly to siproxd 0.7.0 with the new libosip2 library. If for some reason you cannot yet update your libosip2 use siproxd-0.6.1.

Happy new year! For those of you that have finished the party and are looking for some fun - download the snapshot supporting version 3 of libosip2. First you need to install the new libosip2 version (3.x.x), then ./configure and build the snapshot. Note that you can install version 3 of libosip2 to a different location (in parallel to version 2) and tell ./configure where to look for the header and library files:

$ ./configure --with-libosip-prefix=/opt/libosip2-3/

This will expect the header files in /opt/libosip2-3/include/ and library files in /opt/libosip2-3/lib/.
Please report any issues/bugs/problems you find.

During Q1 (likely end of Janary) in 2008 a new major release of sipropxd will be made public that switches from libosip2 version 2 to version 3 (libosip2-3.x.x). With this release (0.7.0), previous versions of libosip2 will no longer be supported.
In parallel, siproxd 0.6.1 will be released which still uses the old libosip2 version 2 but will be functionally equivalent to siproxd 0.7.0. This provides the chance for a smooth switch to the new libosip2 version.

No, we are not dead. After quite some time finally siproxd-0.6.0 is officially released. It includes a number of new features and bugfixes that should give enough motivation to upgrade.

Just to name a few of them:
- Includes RTCP support and a de-jitter feature
- Keep failed DNS attempts in cache for 10 minutes
- Does now masquerade the User-agent header (by configurable string).
- Support for adding ;rport to Via headers (RFC3581)

voipnow.org has as quiet nice overview of VoIP applications and resources that are available.
"74 Open Source VoIP Apps & Resources" covers the H.323, SIP, IAX and RTP protocols and include clients, libraries, gatekeepers, and any other open source resource available for those specific protocols plus PBX and IVR platforms.

This new major release of libosip2 has some basic changes in its data structures. This causes compiling siproxd with this release of libosip2 to fail. For now it is recommended to stick with a 2.x.x version of libosip2, like 2.2.2, the latest version of that major release.

This release basically contains the 64 bit code corrections and some minor fixes. 64-bit users should look for the 0.5.13 release.

Binaries for the on(e)-disk-router fli4l are available here. The binaries are provided "as is" and have not yet been tested.

Note: The TAR archive only contains the siproxd binary itself and not the full OPT_SIP package.
