ClueCon'07 was a remarkable VoIP developer event, one of the best I attended so far. The commercial aspect was low profile, a lot of speeches focusing on the technical aspects. Very interesting were the group meetings of developers, discussing interoperability issues and collaboration mechanisms.
My speech was a general presentation of OpenSER, going to tech stuff as well. Because of many requests, I gave the second presentation Thursday morning, showing real configuration examples of OpenSER, from the simplest one, to more advanced, exemplifying with voipuser.org config. I went through load balancer, presence server, registrar or redirect servers, Perl application example.
Among interesting things there: nice demos from Truphone, FreeSWITCH updates, Ruby library for Asterisk AGI (simple way to create advanced dialing plan), voice transformation and liar detection :-) , Jingle discussion panel.
The slides from my first presentation are at:

VoN Europe 2007
The last VoN in Europe provided another great chance to meet people around the project, learn about latest trends in VoIP and discuss latest businesses in the area.
OpenSER had itself one hour session in the main theater of VoN Exhibition, giving opportunity to present a summary of the project, the status of WeSIP application server, FMC solutions based on OpenSER, as well as the strong bullets brought by 1.2.x release.
The VoN seemed quite this time, some noise around P2PSIP and peering, a lot of FMC discussions, less and less IMS interest. Despite that, we had very nice meetings with VoIPUser friends and open source VoIP developers.
Slides from OpenSER BoF and photos from the event to be made available soon.

OpenSER Advanced Programming Course 2007
Between the 4th and 6th of June 2007, INRIA, the IT research institute of France, hosted in Paris the first edition of OpenSER Advanced Programming Course. The teachers were myself and Bogdan-Andrei Iancu.
We focused on the internals of OpenSER application, touching delicate subjects as memory manager, locking system, data lumps, pseudo-variables, module development a.s.o. The three days were a good opportunity to discuss also about future plans, what should be nice to have, where is the current bottle neck. All agreed that some work in interfacing with database has to be done, maybe some efforts to make parts of script reloading, lumps applying, and, if possible, some asynchronous processing in regard to TCP and DNS.
The attendants span several countries: Australia, Austria, Brazil, Germany, Italy, UK, Romania, Sweden, and, of course, France.

OpenSER at LinuxTag 2007
The full four days at LinuxTag in Berlin, Germany, were an opportunity to meet old folks from the FhG FOKUS Institute, were our trip in VoIP started back in 2001-2002.
The show itself was pretty well organized, with high quality exhibition booths and good presentation. You could see the German style around, even for Open Source, everything has to be perfect.
The VoIP was quite poor represented there, in our corner we were colleagues only with Asterisk, bringing a lot of questions like: "What is the difference between?". We met several OpenSER friends, some time was spent with the squad from SunCC compiler, trying to fix some issues encountering when using this tool with some architecture specific code on Linux.
Next year, the event will be taking place on the same location, allowing more time for advertising. As a plan, will be trial of VoIPing the exhibition infrastructure, so that you can get a device and listen the speeches from your booth or while spinning around.
Some pictures will be posted soon.

eLiberatica - Romanian Open Source Conference
I managed finally to attend eLiberatica, due to some traveling there were some doubts around, and I am glad I did it. So far, Romania was a country where the Open Source still was considered geeks world, not suitable for business. That's mainly because of poor implications of authorities and the usual aggressive attitude of the big players in IT on local market.
Personally I hope, with this event, more eyes turned to Open Source, opening the way of deeper analysis that will conduct to a better understanding of the concept and the maturity of such applications. I have attended many events where the audience was asked " Who is using Open Source?" gathering like 10-15% or hands up, while the question " Who is using Firefox/Mozilla?" got at least 40%.
Open Source VoIP is pretty well represented by Romanians, OpenSER and Yate being worldwide relevant applications in this field. My presentation was focused on the Romanian contribution to OpenSER so far, exposing as well a solution to implement a ITSP using only Open Source applications. This does not mean won't cost you anything, but is lot of money saving and flexibility there.
In the hope that recently constituted ROSDEV (Romanian Open Source Development) group and events like eLiberatica will increase the level of Romanian contributions to Open Source, I will like to give the appropriate credits to Lucian Saviuc who managed to organize a very successful first editions of eLiberatica, gathering well known representatives of important projects in Open Source: MySQL, eZ, PHP, Mozilla, Gnome, Apache.
The event was located in the beautiful city of Brasov, in the middle of Carpathian mountains, about 30km away of Dracula Castle, who, I'm sure :-), enjoyed the event and attendants.
Presentation is available here.
