Kamailio World 2015 – The Workshops

April 15th, 2015

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.

workshops

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.

Be sure you don’t miss Kamailio World Conference 2015, during May 27-29, in Berlin, Germany – it is the open source real time communications event in Europe!

See you in Berlin!

From SQL Tables to Kamailio Hash Tables

April 9th, 2015

kamailio-tricksEloy 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.

You can read the article at:

Using caching is a good way to improve the performances and htable is a very flexible mechanism in Kamailio configuration file, with plenty of options to tune the caching rules.

Enjoy!

Roadmap to Kamailio v4.3.0

March 30th, 2015

Kamailio 4.3The next major release of Kamailio is going to be version 4.3.0.

The plan to release it was sketched during the last IRC devel meeting. The current proposal is to publish the new version by the beginning of June 2015. Given there has to be at least one month of testing, these are our milestones:

  • Freezing the development: Wednesday, April 22, 2015
    After this, only bug fixing will happen in the development branch.
  • The week starting May 18th: If testing goes smooth, then the 4.3 branch in our GIT platform will be created
    At this point, new features can be added to the development branch again.
  • Test more in beta phase, prepare packaging, etc. and release after 2-3 weeks: One of the days between June 4 and 11

Other suggestions or adjustments are welcome! Send them to mailing list for further discussions!
