It is one month till the start of Kamailio World 2015, time has passed very fast since we announced the event, accelerated by April filled with many public holidays.
The first draft of the schedule is now available, as usual, expect many speakers to tune the content of their presentation along the way to the day of the talk, to surprise the audience with challenging concepts and visions.
At this edition we were pleasely surprised by the number of submissions, but it was an extremely hard task to select the sessions. To accommodate as much as possible, we are introducing the lightning talks, two of 10 minutes each, to give the opportunity to present shortly about interesting ideas or updates of applications used in Kamailio and VoIP eco-system.
We are very grateful to our sponsors, which made possible to bring again a consistent number of speakers, ensuring first class quality content for the entire event.
In about 4 weeks, we will be ready to welcome you in the beautiful city center of Berlin. Don’t miss the opportunity to attend this event, it is unique across Europe, bringing open source and real time communications industry together, bridging flexibility innovation with telecommunication businesses. It is now the right time to register!
The development (aka master) branch of Kamailio now enter the pre-release phase for version 4.3.0. No new features are allowed to be pushed to GIT master branch until we create a dedicated branch for 4.3 (expected to be in about 4 weeks or so).
The focus moves now on testing the code, to get it in a stable, rock solid state at the time of release. We hope to get many people from the community involved in testing. If you want to get involved and need assistance about what and how to do it, please don’t hesitate to write to mailing lists. The first step is to get Kamailio installed from sources, details at:
It is now about one month and a half till the start of Kamailio World Conference 2015. Continuing with the same event structure like in 2014, the afternoon of the first day, the 27th of May, is filled with several technical workshops. These sessions are intended to give a more hands-on perspective on the subjects, with deeper technical content.
Last year, Sipwise showed how to deploy sip:provide CE – the open source out of the box IP Telephony Operator Platform – in a matter of minutes and customize it to fit better your needs. This year, Daniel Grotti, a long time SIP and Kamailio fellow, is going to show how to enable WebRTC for sip:provider CE in order to bridge the communication between the web world and the classic SIP phones. Few other typical use cases will be approached during the session.
Carsten Bock, from NG Voice, is returning with another tutorial to show more of what can be done with Kamailio for IMS and VoLTE deployments. Besides the tutorial, the plan is to have a VoLTE testbed on site for the duration of the entire event, so the participants can test with their own devices.
After presenting at the past editions the concept and the development of CGRateS, a carrier grade open source CDR rating engine, Dan Bogos is now coming with a hands-on session about how to integrate it with Kamailio for prepaid and postpaid billing.
Ability to troubleshoot SIP routing and analyze the flows on the wire is one of the core elements required for VoIP engineers. Lorenzo Mangani, one of the co-founders of Homer SIP Capture project, is going to deliver a session on how to use existing open source tools (including Homer and sipgrep, but not limited to) to make the SIP troubleshooting process easier.
All together are providing an amazing amount of knowledge from the people with first hand experience, those that built the systems. It is a unique opportunity at Kamailio World to get face to face to interact with such people.
The content of conference days is filled with other very interesting sessions, including as well valuable technical details, presenting scalable and secure architectures or other products that can be used to complete the VoIP platforms with new features. Right now you can see details for a sections of presentations in the Schedule page.
Eloy Coto Pereiro has published recently another blog post that can be useful in the case one needs to cache content of custom database tables in Kamailio’s memory via htable module. The article uses Postgresql as database server, but same mechanism can be used for other database servers.
Kamailio SIP Server v4.2.4stable is out – a minor release including fixes in code and documentation since v4.2.3 – configuration file and database compatibility is preserved.
Kamailio (former OpenSER) v4.2.4 is based on the latest version of GIT branch 4.2, therefore those running previous 4.2.x versions are advised to upgrade. There is no change that has to be done to configuration file or database structure comparing with older v4.2.x.
