Merry Christmas and Happy Holidays!

Passing the 15 years of development marker for Kamailio project few months ago, we are now approaching the end of 2016. A long list of people devoted a lot of time in sustaining the project with resources for development, support and advertising. So this is a good moment to thank and greet them, everyone involved in Kamailio project, old and new friends, developers, contributors, the engaged and warm community members.
We are very close to the moment of freezing the version 5.0.0, a new major milestone in the project evolution, with a restructured source code tree, cleaner and slimmer code base, a new flexible configuration file framework that allows building SIP routing script in embedded languages such as Lua and Python, a.s.o. – all making a very solid foundation for developing next releases! Good premises to expect a lot of new stuff in 2017!
The 5th edition of Kamailio World Conference, the project’s annual event, is scheduled for May 8-10, 2017, in Berlin, Germany. We look forward to meeting many of the community members there!

Kamailio - MI Code To Be Removed

Management Interface (MI), the old line-based text protocol interface to interact with Kamailio is going to be removed in the near future. It was declared obsolete several years ago, when we introduced the RPC interface. With upcoming version 5.0 already having the code source tree restructured, this step makes a better and slimmer foundation for next generation of releases.
The default configuration file is now shipping with jsonrpcs module and kamctl tool is using the RPC interface via jsonrpcs. The command line parameters for kamctl should be the same like for the past releases, but the output is now in jsonrpc format.
The RPC interface is implemented by the following modules:
  • ctl – binary rpc protocol – with transport layers for FIFO file, unix sockets and IP sockets (both datagram and stream). It is the module used by the kamcmd tool.
  • jsonrpcs – jsonrpc protocol – with transport layers for FIFO file, unix and IP sockets (datagram) and HTTP via xhttp module. It is the module used by kamctl and kamcli tools.
  • xmlrpc – xmlrpc protocol – with transport layer for HTTP
If you were using mi_fifo or mi_datagram modules, then you can switch to jsonrpcs module (it offers the transports for the two mi modules). If you were using mi_xmlrpc, then you can switch to xmlrpc module.
Thanks for flying Kamailio!

Kamailio - Source Code Tree Restructured

Today – Dec 7, 2016 – the source code tree of Kamailio project was restructured into a slim and clean root folder. This was done in order to better handle various components and make it easier to get into the source. You can browse it online at:
Here is a summary with the new locations:
  • src/main.c – the main c file of kamailio application
  • src/core/ – contains the source code for the core, including the subfolders for sip parser, memory manager and other core components
  • src/lib/ – contains the internal libraries
  • src/modules/ – contains the modules
  • utils/ – contains the tools used to operate kamailio such as kamctl and kamcmd
  • etc/ – configuration files
  • doc/ – resources for building documentations and core tutorials
  • pkg/ – packaging specs
  • misc/ – contains related resources, such as config examples, additional tools and scripts, vim syntax highlighting files, …
  • test/ – components related to testing
The Makefiles for building the application are in src/, with a new root folder Makefile that does target forwarding to src/. You should be able to use the same make commands inside root folder as well as inside src/.
The kamailio binary is built in src/ directory.
For example, next are the commands to build and run kamailio from source code tree, with debug mode logging to terminal:
git clone https://github.com/kamailio/kamailio
cd kamailio
make all
./src/kamailio -f etc/kamailio.cfg -L src/modules/ -E -e -ddd
While some small adjustments may still be done, we hope that the new structure is going to make the long term management and development of the project smoother.
Thank you for flying Kamailio!

Snappy Kamailio – TADHack Global 2016 Winner

Coordinated by its founder Alan Quayle, with the help of many local teams across the world, TADHack Global 2016 edition was organized during October 14-16 in over 30 cities, counting over 2600 registrations that resulted in over 170 hacks. It is probably one of the largest hackathons recorded so far, maybe even the largest, anyhow, for sure in the telecom world.
tadhack-2016-global
One of the cities involved in the hackfest was Berlin, the local event was hosted by VoIP Labs, being managed by Dennis P. Kersten. On a rainy weekend, a bunch of VoIP enthusiasts met, paired and started hacking with various telecom APIs offered by the event sponsors. The results were amazing, 4 completed hacks, all of them winning at least one prize, 3 of them being awarded TADHack global prizes — the details about all winners can be found at:
One of the global winning hacks, awarded by Canonical/Ubuntu, was named “Snappy Kamailio” done by Daniel-Constantin Mierla, the co-founder of Kamailio project. The title of the hack is not related to the behaviour of the application, as one could imagine, but to the rather new packaging system known as ‘snap’. Here is the definition of a snap taken from the snapcraft.io:
A snap is a fancy zip file containing an application together with its dependencies, and a description of how it should safely be run on your system, especially the different ways it should talk to other software.
Most importantly snaps are designed to be secure, sandboxed, containerised applications isolated from the underlying system and from other applications. Snaps allow the safe installation of apps from any vendor on mission critical devices and desktops.
Aiming to ease the deployment of applications across different Linux-based systems, wrapped with proper layers of security, the snaps concept look very promising.
Daniel’s remarks on the TADHAck event and its outcome:
“”I am glad that I could participate to the TADHack Global 2016, the local event in Berlin made it easier in a rather busy period of traveling, huge credits to Alan and Dennis for making it possible.
As for the hack, what Canonical/Ubuntu was offering during the hackfest was a perfect fit for me – a Linux/Ubuntu cloud infrastructure to meet the needs of scaling deployments and RTC platforms. As one of core developers of Kamailio SIP server project, I wanted to do something using it, that, after all, can also be useful for our community.
Cloud, virtualization, containers — all very hot concepts these days. But snaps target to be even slimmer, still avoiding annoying issues such as broken dependencies and different versions of libraries on different distributions. I heard about them, but never got the time to play with. TADHack global offered the chance that I didn’t want to miss. The hack-intense environment and discussions with other people around helped to clarify some doubts (hey Torsten, Dominik, Dennis).
Once I started to build snaps and test them running, I realized that the sandboxed snap restricts some privileges that Kamailio uses when running on Linux, such as creating raw UDP sockets. With a bunch of patches after many try-and-errors, I was able to get the stock Kamailio from our github.com repositorybuilt and run as a snap.
It felt that the participation to the TADHack was fruitful already. The prize announced few days later came as a very pleasant complement awarded by Canonical/Ubuntu.
Now I am looking forward to get new versions of Kamailio snaps with a more specific target functionality, such as a load balancer, SIP registrar, a.s.o. Let’s see how far I can go till the TAD Summit, Nov 15-16, 2016, in Lisbon, Portugal, where I will participate and show the Snappy Kamailio and the evolution after the hackfest. If you are in telecom or real time communications looking for future transformations of the market, it’s an event you should definitely attend!””
