Creating A C++ Based Module In Kamailio

Luis Martin Gil from has published a blog detailing how to create a new module for Kamailio using C++. Although Kamailio is written in C, sometimes C++ can be a more convenient programming language for a module, especially if it needs to link against an external C++ library. Another useful benefit can be the ability to use existing unit testing frameworks. These and other benefits are detailed in the article published at:
It is a very good reading, no matter you want to use C++ or C for extending Kamailio.
A couple of years ago, Luis has authored the ndb_cassandra module for Kamailio and has contributed to other modules along the years.
Should you be the author or just be aware of any online tutorial about Kamailio that worth sharing with the community, just contact us. We will be more than happy to publish a news about it.
Meanwhile, we hope to see many of you at the next Kamailio World Conference, May 6-8, 2019, in Berlin, Germany!

Besides bringing a consistent group for distinguished speakers, with every edition we aim to improve the interaction between all the participants. From the first edition of the event we had the VUC Visions panel and Dangerous Demos, along with the cocktail party for social networking. At the previous edition we introduced the Ask Me Anything session with Kamailio core developers.
In 2019, we are adding two new sessions to offer even more chances that the participants know each other and network between them, opening the doors for partnerships and collaboration. These are:
  • Your Deployment On Stage – 5 Minutes 5 Slides – the session is coordinated by Markus Monka, head of IT infrastructure at In this session any participant can come in the front of the others and speak about how they use Kamailio or what they are offering in the VoIP/RTC space. Think of it as a quick exposure, letting the others notice your presence so they can approach during the breaks or social networking event for further discussions. Time is limited, the proposals will be accepted in the order they are received. You can contact us starting now and get your 5min — use the web form for it. Important note: this session is not for accepted speakers, but for the registered attendees.
  • Berlin City Tour By Boat – with special credits to for sponsoring it, this new social networking event during the evening of May 6, 2019, aims to offer a relaxing time combine sightseeing in the beautiful city center of Berlin with enjoying a few drinks, overall enabling more chances to chat between us.
Looking forward to meeting many of you in Berlin at Kamailio World Conference 2019! You still have the chance to secure your seat now at the early registration fee:

Kamailio Exporter For Prometheus In Golang

Via social media media, I noticed a nice article about a Kamailio exporter for Prometheus written in Golang:
So I thought sharing it further via Kamailio’s website. Lately I noticed an increase of interest on using Prometheus, hopefully this exporter tool will help others inside our community.
As a matter of fact, one of the submissions for the next Kamailio World Conference (May 608, 2019, in Berlin) is about using Prometheus with Kamailio for visualising statistics and other metrics via Grafana dashboards (to avoid any confusions, it is not from the author of the linked article in this text). The schedule of the event is expected to be published in the near future, meanwhile you can view a selection of accepted speakers. Early bird registration is still open, if you want to benefit of the discounted access, hurry up to register!
Thanks for flying Kamailio!
