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.

OpenSER 1.3.0 campaign started
As OpenSER community got used, after about one month since a major release, the campaign for the next major release begins. For the roadmap, an initial IRC meeting happened on the 20th April (see summary and roadmap draft).
However, meanwhile quite a lot of brand new code was pushed on public SVN. SIMPLE-XMPP Presence gateway came to light via pua_xmpp module, to complete the IM gateway. Another interesting addition in Presence side is the Shared Line Appearance (SLA/BLA), very useful when trying to accomplish a signaling PBX (pua_bla).
Furthermore, perlvdb (perl virtual database) module allows any kind of data source mapped over DB API, opening new possibilities, like LDAP authorization and authentication. The list ends now with cfgutils, a new module to gather interesting utilities for configuration file (e.g., random value, sleep).
Besides that, tracker has several other modules submitted by third party contributors, waiting the review before the admission to SVN: auth_identity - SIP identity authentication; auth_avp - AVP-based authentication; auth_ldap - LDAP-based authentication; benchmark - small module to perform benchmarking from configuration file

Advanced OpenSER Programming Course
First Advanced OpenSER Programming Course will take place in Paris, hosted by INRIA, June 4-6, 2007
Following some discussions started during first OpenSER Summit, we are happy to announce that first Advanced Programming Course will happen very soon. Courtesy of INRIA (many thanks to Philippe Sultan) we have the room and a good connected location. There will be three full days of deep analysis and survey of internal architecture and structures, best practices to add new features, optimizations and OpenSER's specific components (memory manager, locking system, ...).
The course is dedicated to people willing to develop OpenSER extensions. It will be a class of 14 persons. The participation fee will be just to cover the logistic required for this event, estimated to be about 150-200Euro per person, for the full course (mainly is subject of how many participants will be registered).

OpenSER 1.2.0 - Perfomance Tests
We took the time to do some performance tests for two of the most important components of OpenSER 1.2.0: transaction module (tm module) and user location (registrar and usrloc modules).
The results show the capacity that can be handled by the two components, which should move the concern that they are bottle neck in a VoIP system. The numbers are higher than what one would want to deploy in real life within only one physic VoIP server.
TM got performance of processing over 28 millions complete calls per hour while user location can handle registration coming from over 4 millions phones with an average of 10min for expiration time. Testing server was an ordinary desktop, Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz, 1GB of memory, 100Mbs Ethernet card.

OpenSER v1.2.0 Released
News from:
http://www.openser.org/mos/view/News/NewsItem/OpenSER-v1.2.0-Released/
After about 8 months since the last major release, with about 6.5 months of development and 1.5 of extensive testing, OpenSER version 1.2.0 is out. This version brings a lot of new features and improvements to existing code. Can be defined as the biggest improvement between releases so far. Configuration script has new directives while some of the old one were removed or replaced with a new form.
Dokuwiki page has been created to track these changes and to ease the migration:
http://openser.org/dokuwiki/doku.php/install:1.1.x-to-1.2.x
The range of use cases was largely increased, important achievements toward SIP Application Server were added by seas and perl modules, which allow writing Java SIP Servlet extensions and Perl Applications for OpenSER. Meanwhile, the old core components were substantially improved, using OpenSER as SIP proxy, registrar or simple router for load balancing or least cost routing being more flexible and faster.
We would like to thank for the work, suggestions and contributions to this release to all people supporting the project.

OpenSER - Summary of 2007
2007 was a year full of achievements and events for OpenSER. We had a major release in summer (1.1.0), and a continuous increase in features set and robustness. What was new in 1.1.0 was summarized in release news:
http://www.openser.org/index.php?option=com_content&task=view&id=47&Itemid=68
Since then we went though many milestones. We had the first OpenSER summit where we were able to meet many folks from the lists, have nice chats and present interesting VoIP solutions based on OpenSER.
http://www.openser.org/index.php?option=com_content&task=view&id=57&Itemid=71
A very important statistic is the number of new modules and features introduced in current development version after 1.1.0:
- domainpolicy - policies to connect federations
- imc - instant messaging conferencing
- mi_fifo and mi_xmlrpc - FIFO and XMLRPC transports for the new management interface (MI)
- perl - embed perl programming in configuration file
- presence - SIMPLE Presence Server implementation
- pua, pua_mi, pua_usrloc - presence user agent client implementations for user location records and management interface
- seas - connector to SIP Application Server - WeSIP - Java SIP Servlet Application Server (http://www.wesip.eu)
- snmpstats - SNMP (Simple Network Management Interface) interface to OpenSER statistics
- sst - SIP session timer support
- xmpp - transparent SIP-XMPP gateway
Documentation and news about all these:
http://www.openser.org/docs/modules/1.2.x/
http://www.openser.org/index.php?option=com_content&task=blogsection&id=2&Itemid=9
A lot of other significant improvements and addons were included in existing code (management interface, fetch database support, postgres, usrloc, dialog, enum, acc modules polishing), openser web administrator was developed. There is not very long time to the next release, along with few pending new features, the next period will be allocated to core components like timers, dns and configuration file flexibility. By end of January we should approach a new testing phase.
This year the OpenSER community collaboration exploded, dokuwiki has lot of content, many tutorials were submitted, new developers and many modules sponsored by companies, mailing lists and web forum are places to get reliable information about OpenSER...
We want to thank to all of you (developers, contributors with patches, tools and documentation, testers and OpenSER users) for supporting the project. 2006 was a very good year for OpenSER and 2007 looks very challenging.
