New Kamailio module – app_lua_sr

Fri, 05/31/2019 - 13:25
A new module named app_lua_sr has been pushed to git master branch. It collects the functions that correspond to the Lua srlibrary, previously exported from app_lua module:The Lua sr library is the old way of exposing Kamailio API to Lua scripting. With the introduction of KEMI in Kamailio v5.0, the KSR library has been exported to Lua, with a larger set of functions, therefore over the time app_lua_sr will be deprecated and removed. Splitting the code from app_lua that is no longer needed for KEMI is the first step in this process.If you are using sr library in your Lua script, consider to migrate to KEMI alternatives offered by KSR library. For now you can still keep your old Lua script with sr library, requiring following updates to kamailio.cfg:# old config
loadmodule "app_lua.so"
modparam("app_lua", "register", "sl")
 
# new config
loadmodule "app_lua.so"
loadmodule "app_lua_sr.so"
modparam("app_lua_sr", "register", "sl")If you find a function available in Lua sr library but not in Lua KSR library, contact us via mailing lists or open an issue on github tracker.Thanks for flying Kamailio!

Kamailio – Updates To Command Line Arguments

Fri, 05/17/2019 - 13:23
Recently, a series of commits focused on updating the command line arguments for Kamailio. With an increased popularity of deploying Kamailio in containerised environments, the flexibility of using command line arguments when starting the SIP server can simplify the orchestration.For long time, Kamailio accepted only arguments with short name (single character argument name), so one of these new additions was the option to handle arguments with long name, opening the door to add a lot more variants.The list of command line arguments is printed by running ‘kamailio -h‘, with the version built from the latest Git master branch, these are:# kamailio -h

version: kamailio 5.3.0-dev5 (x86_64/darwin) 104147-dirty
Usage: kamailio [options]
Options:
-a mode Auto aliases mode: enable with yes or on,
disable with no or off
--alias=val Add an alias, the value has to be '[proto:]hostname[:port]'
(like for 'alias' global parameter)
-A define Add config pre-processor define (e.g., -A WITH_AUTH,
-A 'FLT_ACC=1', -A 'DEFVAL="str-val"')
-b nr Maximum receive buffer size which will not be exceeded by
auto-probing procedure even if OS allows
-c Check configuration file for syntax errors
-d Debugging mode (multiple -d increase the level)
-D Control how daemonize is done:
-D..do not fork (almost) anyway;
-DD..do not daemonize creator;
-DDD..daemonize (default)
-e Log messages printed in terminal colors (requires -E)
-E Log to stderr
-f file Configuration file (default: /tmp/kamailio-dev/etc/kamailio/kamailio.cfg)
-g gid Change gid (group id)
-G file Create a pgid file
-h This help message
--help Long option for `-h`
-I Print more internal compile flags and options
-K Turn on "via:" host checking when forwarding replies
-l address Listen on the specified address/interface (multiple -l
mean listening on more addresses). The address format is
[proto:]addr_lst[:port][/advaddr],
where proto=udp|tcp|tls|sctp,
addr_lst= addr|(addr, addr_lst),
addr=host|ip_address|interface_name and
advaddr=addr[:port] (advertised address).
E.g: -l localhost, -l udp:127.0.0.1:5080, -l eth0:5062,
-l udp:127.0.0.1:5080/1.2.3.4:5060,
-l "sctp:(eth0)", -l "(eth0, eth1, 127.0.0.1):5065".
The default behaviour is to listen on all the interfaces.
-L path Modules search path (default: /tmp/kamailio-dev/lib64/kamailio/modules)
-m nr Size of shared memory allocated in Megabytes
-M nr Size of private memory allocated, in Megabytes
-n processes Number of child processes to fork per interface
(default: 8)
-N Number of tcp child processes (default: equal to `-n')
-O nr Script optimization level (debugging option)
-P file Create a pid file
-Q Number of sctp child processes (default: equal to `-n')
-r Use dns to check if is necessary to add a "received="
field to a via
-R Same as `-r` but use reverse dns;
(to use both use `-rR`)
--server-id=num set the value for server_id
--subst=exp set a subst preprocessor directive
--substdef=exp set a substdef preprocessor directive
--substdefs=exp set a substdefs preprocessor directive
-S disable sctp
-t dir Chroot to "dir"
-T Disable tcp
-u uid Change uid (user id)
-v Version number
--version Long option for `-v`
-V Alternative for `-v`
-x name Specify internal manager for shared memory (shm)
- can be: fm, qm or tlsf
-X name Specify internal manager for private memory (pkg)
- if omitted, the one for shm is used
-Y dir Runtime dir path
-w dir Change the working directory to "dir" (default: "/")
-W type poll method (depending on support in OS, it can be: poll,
epoll_lt, epoll_et, sigio_rt, select, kqueue, /dev/poll)Among the latest argument additions:
  • add domain aliases with –alias
  • set advertised address to listen sockets speficied with -l socket/advertise
  • set server id with –server-id
  • set a subst, substdef or substdefs preprocessor expression with –subst, –substdef or –substdefs
Couple of more will be added in the future, aiming to make it easier to control Kamailio from command line. If you have suggestions, do not hesitate to propose them to sr-users mailing list.Thanks for flying Kamailio!

Creating A C++ Based Module In Kamailio

Fri, 03/29/2019 - 21:00
Luis Martin Gil from zaleos.net 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!

Kamailio – Open Source Excellence Award At SimCon 2019

Sat, 02/09/2019 - 21:47
We are delighted to announce that Kamailio project was awarded the “Open Source Excellence” prize at SimCon 2019, ceremony hosted by Rachel Riley (twitter – wikipedia) and Simon Woodhead (twitter).From their announcement:Kamailio were awarded ‘Open Source Excellence’, a key reason being the superb management of the project. Kamailio is used within huge networks and really is the secret weapon of many modern telcos. It is open source and, in the judges’ opinion, one of the best run projects around.This recognizes the enormous effort made over more than 15 years by the development team and the community to keep Kamailio at the top of open source SIP/VoIP server applications, with a well defined development process and project organizing procedures.With key targets such as flexibility, robustness, security and scalability, Kamailio continued to bring constantly a consistent set of new features with each major release (19 of them, from SER 0.8.x to Kamailio 5.2.x) and consolidated the trust in being a reliable application that can be used from start-ups to large established telcos and mobile operators.It is actually a double celebration, because Fred Posner (twitter), one of our most prominent community members and advocate, was also awarded — citing: a genuine ‘Pre-Posthumous Legend’, a selfless, long standing contributor and supporter of the open-source community who has never sought the limelight.Thank you SimCon for the award and Simwood for supporting the project for so many years!We look forward to Kamailio World Conference 2019 and hoping to meet many of you there!Thanks for flying Kamailio!

Fosdem 2019 Remarks

Wed, 02/06/2019 - 23:30
Fact that open source development is huge nowadays couldn’t be felt better than at Fosdem 2019, practically during the first day was almost impossible to move around even on the corridors. It is irrelevant to say that I gave up quickly in the morning trying to attend any session, after failing to find seats in two of the rooms I wanted to get in.Therefore the first day resumed to hallways, expo areas and cafeterias, meeting and chatting mainly with fellow Kamailians and VoIP/RTC folks. I got also the chance to see again and catch up with couple of other projects and organizations, among them: FSFE, OSI, SFC, the main Linux distros, Fossasia or GSoC.Back to real time communications, being again being again part of organizing team for the DevRoom and the lounge…The lounge was available during the both days, as usual filled with many XMPP projects and devs, joined by the Matrix.org team. The SIP/VoIP folks were never attracted by the lounge during all these years, but we always had a stronger presence in the DevRoom.The RTC DevRoom took place in building H, with a fair large space accommodating about 150 seats, allowing us to run smooth during the day. I haven’t done much on Sunday apart of helping around and chatting with folks just outside.Henning gave a presentation on what’s new lately on Kamailio project. Asterisk, Matrix, Homer SIP Capture, reSIProcate and CGRateS had their usual presentations as well and WebRTC was also a relevant stake of the day. A new comer this year was the sip3.io project, another SIP capture and troubleshooting tool. Of course, some presentations were about XMPP, open source devs doing a lot of cool stuff with that protocol as well.On Saturday, we had our informal developers meeting about Kamailio, among participants, besides myself (Daniel-Constantin Mierla), there were Henning Westerholt, Federico Cabiddu, Alexandr Dubovikov and Dragos Oancea. Four were also at the developers meetup in Dusseldorf and we agreed that was something very productive and we should do it again. Couple of ideas were discussed about short term development, more to be announced via mailing lists.The top of the event was as usual the dinner, done by Kamailio project every Fosdem edition since 2009 (see who was there 10 years ago). Like in the past few years, we were joined by other VoIP devs participating in the DevRoom, being nearly 40 participants (to give few more names: James Body, Tim Panton, Dan Jenkins, Daniel Pocock, Joachim Vanheuverzwijn). Lot of fun and interesting discussions!Big thanks to Voxbone.com for sponsoring it and to Torrey Searle for helping to organize the dinner!And to attract more of you to contribute to open source (and Kamailio), I have to mention that I got one of the most amazing gifts in more than 17 years of OSS development: home made Belgian chocolate truffles, amazing taste (thanks Joachim/Zoiper)!Till the next Fosdem, I am looking forward to meeting many of you at the next Kamailio World Conference, May 6-8, 2019, in Berlin, Germany! Registration is open!Thanks for flying Kamailio!
