Updates of NAT Traversal Solutions for OPENSER

There were lot of development efforts in the two options available for NAT traversal with OPENSER.

Mediaproxy relesed next generation version: v2.0. More details at:

Rtpproxy brings lately lot of new stuff, information is available at the dedicated site:

Very interesting approach of “451 CAOE Theory” related to European Football Championship 2008. They are going to analyze the presence of Open Source in the countries paying there, selecting the winner based on best performances with Open Source. More details at:

Romania is playing there and the Open Source part of the game happened.

Typically, some comments were out of the scope, just to label them only like this. Indeed, it is lot to do with respect to Open Source in Romania.

I got in touch with Open Source in my first University year. It can be an excuse that after communist regime it took some time to put the country on the right movement, but it still happens now, people get in touch with Linux at University, if they follow software programming. Otherwise, Open Source, Linux mainly, is like a Morgana, rumors that exists, but nobody tells something about it in the educational system.

As there are many Open Source applications running now on Windows, lot of people are not aware they use Open Source — case of Firefox or Open Office.

ROSDEV and eLiberatica are Romanian events that try to promote Open Source and I hope they will succeed. But will take time. As long as the educational system does not produce a minimal knowledge about Linux and other Open Source applications, the local business cannot afford trainings. I am not talking about IT companies, but about the rest which represents more then 90%. I can say that all I do privately with my laptop or as business with ASIPTO and Kamailio (OpenSER) is 99% Open Source, that is insignificant at country level.

I am dreaming to the moment when going to Travel agency, administrative offices, a.s.o. I will see a Linux Desktop running … for sure I will blog it …

Approaching OPENSER v1.4

The time for a new major release is approaching. Last minute discussions about some lately introduced code keeps the situation a bit unclear for the moment regarding the release day.

However, this post tries to underline the new features and important aspects that happened during last development cycle.

There are six new modules:
- db_oracle - database driver to connect directly to Oracle servers
- dialplan - regular expression based dialplan management
- nat_traversal - helper for nat traversal
- peering - RADIUS based peering
- ratelimit - call rate control module
- userblacklist - user based blacklisting

Lot of other new features and refurbishing in existing modules such as carrierroute, dispatcher, dialog, mediaproxy, msilo, cfgutils, pdt, textops.

Review of the DB API, fixup functions, new transformations and pseudo-variables are some of the core updates.

Related to this cycle, worth to mention the first OPENSER Devel Guide, a free, electronic book available at:

http://www.asipto.com/pub/openser-devel-guide/

and first printed book about OPENSER:

Building Telephony Systems With OPENSER.

I encourage everyone to start testing the upcoming OPENSER 1.4. Will be a big step forward.

OPENSER Dinner, Berlin - remarks

What can I say first, great beer! Although, since I have been there last time, the place has changed the name, still nice and good quality.

The talks focused a bit on the two events taking place in Berlin, the AsteriskTag and the LinuxTag. Part ot SUN/OpenSolaris team joined us -- some one there worked hard in the past to make OPENSER compiling on OpenSolaris with the native compiler. Thanks.

As the VoN show in Amsterdam was canceled, this was the last social event in this cycle. I returned to work at ASIPTO, preparing for a new major release.

AsteriskTag and LinuxTag 2008 - week in Berlin

I covered a bit about AsteriskTag2008 and LinuxTag2008 at:

http://www.asipto.com/index.php/2008/06/04/remarks-asterisktag-and-linuxtag-2008/

There you can find links to some photos and the slides I presented in the first day of AsteriskTag.

I had no photos from the OPENSER dinner in Berlin, on the 28th, but I will post about soon.

OPENSER Dinner, Vienna - remarks

Very good restaurant - delicious food and local made beer - credits for selection goes to Andreas Granig. Located in the old part, in the city center, the place was somehow protected by the tourists crowd, offering a quite atmosphere.

As we got two visitors from Bratislava, Slovakia, the discussions went global wise. A hot topic (I guess not only there) was the cancellation of VoN show in Amsterdam. What will be the meeting place from now on for the VoIP guys as the VoN disappeared? Who knows, lot and lot of discussions and opinions here and there on the web forums and mailing lists...

Personally I got an update regarding WiMAX, deploying phase started in some countries. Although I know there are still many issues, the pressure of production environments will give more confidence and attract investors and creation of new or better products and solutions for this technology.

And of course, answering many times, again and again, it is VoIP in that dark castle in Transilvania, only SIP, SIP, SIP (I think is actually lower case :-) )...

Interview: Mysql and Openser

I have found an interesting interview by MySQL with Juha Heinanen, developer and management board member of Kamailio (OpenSER) Project. Targeting the carrier grade deployments, the key components approached are the MySQL cluster and Kamailio (OpenSER), to leverage reliable and distributed storage system for routing large volume of VoIP calls.

See the interview here.
