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.

CERF 2008

The biggest IT show in Romania, CERF2008, took place last week at ROMEXPO facilities in Bucharest. I arrived late on Saturday from Barcelona (some pictures here), so I could pay a visit in the last day of the event.

It looked a bit smaller for me than last year. I was focused on communications technologies, and, apart of the big mobile operators and telco here (Romtelecom, Vodafone, Orange, Cosmote) having large exhibition area, very noisy, advertising latest services, giving gifts a.s.o., the companies came with interesting solutions and hardware to demo and present.

I could find several distributors for the major VoIP vendors, especially for phones and SOHO routers: Zyxel, Snom, Polycom, Linksys, DrayTek, Siemens. I can say I was satisfied by the show, comparing with last years, the Open Source seems more popular, the companies offering VoIP solutions, although they might be from other vendors, they do know about Asterisk or Kamailio (OpenSER).

Bacelona, Barcelona

Third time in Barcelona, same good atmosphere and food. The weather was nice in the first days, ending with heavy raining on Friday afternoon and Saturday.

The training was organized by and hosted by Of course, enjoying Olle ( just one week after the class in Orlando, we got to the usual: setting the infrastructure from scratch in the class Monday morning, leaving everything clean on Friday afternoon.

In between, we had yet another challenging week – no class is similar with the previous one – new inquires from the students, other issues brought to discussion, new labs to be solved. We agreed that we do learn a lot, as people coming to the class use Asterisk and Kamailio (OpenSER) is rather different use cases and they face situations we would have never thought.

We were very closed to Sagrada Familia, having nice surroundings for evening walks and dinners. On the 6th we went to Kamailio (OpenSER) Social Networking Event. A new post here and couple of photos on will reflect that evening.

Oracle Support

Courtesy of Iouri Kharon, a new developer, the development branch of OPENSER includes now native support for connecting to ORACLE databases. Previously possible via UNIXODBC driver, the new module named db_oracle brings more flexibility when using this powerful database server.

The readme of the module is available at:

The module will be include in next major release 1.4.0.

Trip in Florida

Starting with 19th of April, I spent almost twoo weeks in Florida. Arriving 2 days before the SIP Masterclass in Orlando held together with Olle E. Johansson allowed accommodation with the time zone. Also, we had the time to do the shoppings for the course.

First Sunday we headed to Cape Canaveral to visit the NASA Space center. Having my sister a researcher and PhD in Astro-Physics (blogging in Romanian about this at, I have been pretty much in touch with this field. However, the center is impressive, movies about the history of astronautics and the trips in space, rockets and shuttles at real size, the assembly room, launch pads, a.s.o.

Monday to Friday was mostly about the course, with people from USA, Columbia, Peru and Canada, enjoying very much discussion about real world deployments and issues. During an evening, we had a quick tour at Universal Studio, another big attraction of Orlando.

Once course finished, without visiting the Disney World (next time…), I moved to Miami and spent 3 challenging days with friends, including one BBQ on the beach.

I left Florida for going to Bucharest for one and a half day before flying to Barcelona for another SIP Masterclass hosted by
