OpenSER 1.2.3 Released

On the 20th of December 2007, a patch release for old 1.2 stable series was released as 1.2.3. Those running 1.2 branch and have no time or interest to upgrade to 1.3 branch (first stable release in this branch was out on the 13th of December 2007 as 1.3.0) should upgrade to 1.2.3, as it provides higher grade of stability.

The config file is full-compatible with any previous version in 1.2 branch, so the upgrade from 1.2.2 to 1.2.3 shall go smooth.

OpenSER v1.3.0 Released

On the 13th of December, 2007, OpenSER reached the milestone of version 1.3.0.

There are many new modules, lot of enhancements in functionality and robustness. The migration from series 1.2.x to 1.3.0 should be pretty easy, check:

Fall Boston 2007 Follow Up

Another major VoIP event just ended. Time spent there was too short, or I was too busy in those few hours I could roam freely to get the real pulse of the show. The next day was full for me with the OpenSER Admin Training Session and BoF.

Those interested in the materials, follow next link and download the slides from the course of BoF session:

Beside OpenSER-dedicated day on the 1st of November, I attended the "Asterisk & OpenSER: A balanced network strategy", part of the Digium Asterisk World, and I was pleased to see large interest in using the two applications together. It is clear to more and more people that the two are completing each other, not competing. The efforts to make the integration easier show now the results.

As usual, several active members from the community showed up, being nice to associate names with faces and chat a bit.

OpenSER BoF at VoN Fall Boston 2007

Along with the OpenSER admin training session, the project has the opportunity to show its presence in the market within 1h15 session, just after the lunch on the 1st of November, starting with 12:45.

The panelists are:

Alan Crosswell, Senior Director - Network Infrastructure, Columbia University
Daniel-Constantin Mierla, Co-Founder OpenSER
James Body, Director - Networks, Truphone
Jim Dalton, CEO, TransNexus
Norman Brandinger, President, GOES.com
Xavier Casajuana, CEO, VozTelecom - OIGAA

I will do a short update of the project status, where we are and what should make you move to upcoming 1.3 release as soon as it is released. Alan will share his experience in using OpenSER and Open Source to build the VoIP communication platform in one of the most famous Universities in IT, James will continue his story with OpenSER and Mobile VoIP, while Jim comes to present the OpenSER and OSP, a true solution for peering. Norman, old OpenSER folk, very active in the community, will speak about what is keeping him connected to the project and how the project helps his business. Xavier is just to speak about his latest VoIP innovation, OIGAA, where O is from OpenSER ( ;-) )

OpenSER Admin Course at VoN Boston 2007

Last minute arrangements allowed to host one day of OpenSER Admin Training session within VoN Fall Boston, Nov 1, 2007. Despite of late notice, I hope that those interested in the topic can make it to the event. The course is covering hot topics as scalability, HA and security.

Berkely DB Support

Courtesy of William Quan, of CISCO Systems, a new DB module has been submitted to the trunk that incorporates the Berkeley DB into Kamailio (OpenSER). This module depends on Berkeley DB, which is a high-performance embedded DB kernel.

The Berkeley DB offers a couple of architectures:
1. Concurrent Data Store (CDS)
2. Transaction Data Store

This module uses the CDS model. One of the main differences between these architectures is DB recovery and robustness (Please refer to the Berkeley DB for full details). In a nutshell, the onus of recovery is on the application (e.g. openser). This modules contains a recovery program utils/db_berkeley/bdb_recover that can be used to recover DB files.

Like other DB modules, the DB must be created before Kamailio (OpenSER) can be started. The standard openserdbctl script can be used to create the DB once the Berkeley DB is installed.


See the readme file for db_berkely module and the news at kamailio (openser) site.

Freezing in one week for 1.3 release

Time to prepare a new major release for OpenSER is approaching. In about one week the code will be frozen, as we plan to have next major release 1.3 out in November-December time frame.

It is the time to do the commits of the features you want in 1.3. To list what other important changes happened in this respect within last weeks:
- refurbishment of the pseudo-variables allowing to access AVPs and headers with a dynamic index
- "while" statement allowing to iterate through the AVPs/headers
- usage of special processes in nathelper to send keepalive NAT pings, improving a lot the scalability
