Merry Christmas and Happy Holidays!

Here we are again approaching another end of the year, the 17th since the project was started. More than ever, the year of 2017 has been full of activity, both development and community interactions. We had two major releases, 5.0 in February and 5.1 few weeks ago in December – likely the year that brought most of new features ready for production from the history of the project. We are grateful to all developers and community members that contributed to all these efforts!

The 5th edition of Kamailio World happened in the spring of 2017, now we prepare for the 6th edition during May 14-16, 2018, in Berlin, Germany. We look forward to meeting many of the community members there!

Merry Christmas and Happy Winter Holidays!

Santa is flying Kamailio!

Kamailio v5.1.0 Released

December 11, 2017: Kamailio v5.1.0 is out –  a new major release, bringing new features and improvements added during about eigth months of development and more than one and a half month of testing.

In short, this major release brings 9 new modules and enhancements to more than 50 existing modules, plus components of the core and internal libraries as well as exported functions to embedded interpreters (KEMI framework) from more than 100 modules. Detailed release notes are available at:

• https://www.kamailio.org/w/kamailio-v5-1-0-release-notes/

This is the second major release in the series of 5.x.y versions. Besides adding plenty of new features, a lot of development was directed to export existing config functions to KEMI framework, most of them being now available to be used inside scripts executed by embedded interpreters, respectively by Lua, Python, JavaScript and Squirrel.

Enjoy SIP routing in a secure, flexible and easier way with Kamailio v5.1.0!

Thank you for flying Kamailio and looking forward to meeting you at Kamailio World Conference 2018!

Dispatcher Latency Stats Monitoring With Statsd

Julien Chavanton shared via Kamailio sr-users mailing list a Python script that helps monitoring dispatcher latency stats with statsd.

Latency stats for dispatcher were added by Julien during the development cycle of Kamailio 5.1 (this is the next major release to be out in about one week).

The sample script is attached, it will post data to statsd and is working in cron

The feature can be enabled :

You have to enable the latency stats in dispatcher via the module parameter ds_ping_latency_stats:

• https://www.kamailio.org/docs/modules/devel/modules/dispatcher.html#dispatcher.p.ds_ping_latency_stats

This is one use case of this feature, another one will be to load balance based on congestion detected on latency, a follow up on using it is planned for the future.

The Python script is:

#!/usr/bin/python
import subprocess
from time import sleep
import time

# URI: sip:10.10.1.1:5060
#0 FLAGS: AP
#1 PRIORITY: 12
#2 LATENCY: {
#3      AVG: 30.529000
#4      STD: 4.849000
#5      EST: 30.999000
#6      MAX: 1270
#7      TIMEOUT: 0

def server_stats(ip):
   idx = -1
   for line in dlist.splitlines():
      if idx == 5:
         est_latency = line.strip()
      if idx == 7:
         timeout = line.strip()
      if idx >= 0:
         idx = idx + 1
      if line.find("URI: sip:{}".format(ip)) > 0:
         idx = 0

   if timeout[:9] == "TIMEOUT: ":
      timeout_count = timeout[9:]
      cmd = "echo \"fastlink.timeout.{}:{}|g\" | nc -w 1 -u 127.0.0.1 8125".format(ip, timeout_count)
      subprocess.call(cmd, shell=True)
      print(cmd)
   if est_latency[:5] == "EST: ":
      latency = est_latency[5:]
      cmd = "echo \"fastlink.latency.{}:{}|g\" | nc -w 1 -u 127.0.0.1 8125".format(ip, latency)
      subprocess.call(cmd, shell=True)
      print("est latency:{}".format(latency))

servers = ["10.40.5.175", "10.40.2.233", "10.40.1.103"]
interval = 10
it = 0
while it < 6:
# while 1:
   ts = time.time()
   print("[{}]now:{}".format(it,ts))
   next_ts = ts + 10
   it = it + 1
   dlist = subprocess.check_output(["/usr/bin/docker","exec","kamailio","kamcmd","dispatcher.list"])
   for ip in servers:
      print(ip)
      server_stats(ip)
   ts = time.time()
   print("sleeping:{}".format(next_ts - ts))
   wait_ts = next_ts - ts;
   if wait_ts < 0:
      wait_ts = 7
   sleep(wait_ts)

Kamailio Git Branch 5.1 Created

The GIT branch 5.1 for Kamailio project has just been created, it will host the release series v5.1.x. To get this branch from GIT, you can use:

 git clone https://github.com/kamailio/kamailio.git kamailio
 cd kamailio
 git checkout -b 5.1 origin/5.1

Hopefully in two-three weeks time frame the full release of Kamailio v5.1.0 will be out.

From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 5.1. No new features can get in branch 5.1. Enhancements to documentation or helping tools, as well as kemi exports are still allowed. If you are not sure about doing or not a backport, ask on sr-dev mailing list.

The master branch can now get new features, which will be part of the future 5.2.x release series.

Thanks for flying Kamailio!

ClueCon Weekly With Fred Posner

FreeSwitch project is running a weekly video conferencing call for many years now, named ClueCon Weekly. Kamailio project has been present several times in the past.

The edition from Wednesday, Nov 8, 2017, has Fred Posner as a guest. Long time Kamailio community member and advocate, Fred invites you to attend the session and be part of the discussions about Kamailio and FreeSwitch, how to use them together for building modern real time communication systems.

How to connect to the conference call is detailed at:

• https://freeswitch.org/confluence/display/FREESWITCH/ClueCon+Weekly+Conference+call

For video you need an WebRTC capable browser, but there are good options to connect only for audio, via SIP or even from PSTN or mobile phone — very convenient ways to listen while still working.

Thanks for flying Kamailio!

OSS IRIS Broadcast Project Launched

Olle E. Johansson, a very long time community member and developer of Kamailio, has announced the launch of IRIS Broadcast Project, an open source radio broadcast software:

• https://irisbroadcast.org

“”IRIS Broadcast is a project founded in Sweden to publish Open Source software for professional radio broadcast.

Our solutions are based on the EBU and IETF standards and are built for national public radio to manage our external contribution platform.””

Olle had a related presentation at Kamailio World Conference 2017 (video), talking about using Kamailio in radio bradcasting industry.

The code of IRIS project is published on Github at:

• https://github.com/IrisBroadcast

It includes the repository that shows how to configure Kamailio to use it as part of IRIS project:

• https://github.com/IrisBroadcast/connect

With the inevitable phaseout of ISDN lines in the next years, SIP has been more and more adopted in the broadcasting industry, allowing open source RTC software to enter easier into this market.

Wishing all the best to IRIS project and looking forward to more usage of Kamailio beyond IP telephony.

Thanks for flying Kamailio!

AstriCon 2017 Remarks

The 2017 edition of AstriCon was very intense, or at least it was for me (Daniel-Constantin Mierla, Asipto) and the Kamailio presence at the event. Three days without any time to rest!

Before summarising the event from personal perspective, I want to give credits to the people that helped at Kamailio booth and around. Big thanks to Fred Posner (The Palner Group, LOD), he did the heavy lifting on all booth logistics, from preparing required things in advance, setting up the space, banners and rollups, stickers, a.s.o. Of course, Yeni from DreamDayCakes baked again the famous Kamailio and Asterisk cookies, very delicious bits that people could taste at our booth.

Carsten Bock from NG-Voice was there with his Kamailio-VoLTE demos and devices. Torrey Searle’s giveaways from Voxbone were very popular again. Alex Balashov from Evariste Systems ensured that anyone in doubt understands properly the role of Kamailio in a VoIP network and the benefits of using it along with PBX systems. Joran Vinzens from Sipgate completed our team, being around as we needed.

It was a great time to catch up with many friends, VoIP projects and companies in the expo area, sharing the space with Dan Bogos from CGRateS project, chatting with the guys from Obihai, IssabelPBX, FreeSwitch, Janus WebRTC Gateway, Simwood, Bicom, Homer Sipcapture, Telnyx, Greenfield…

There were four presentations by the people at the booth — I, Carsten, Fred and Joran had talks on Wednesday or Thursday. On Tuesday, I, Fred and Torrey participated to AstriDevCon, as always a very good full day session with technical debates, with Mathew Friedrikson and Matt Jordan coordinating and talking about what’s expected next in Asterisk.

Close to the end of the event on Thursday, it was the open source project management panel, with me among the panelists. Being completely warmed up and with some pressure from James Body, I also did the Dangerous Demos, where the Ubuntu Phone decided to reboot as I was on stage, leading me towards the Riskiest Demo Prize (aka Crash & Burn). Carsten and Torrey did dangerous demos as well, with Carsten being the runner up on one of the tracks, which secured him a nice prize as well.

Kamailio related presentations will be collected at:

• https://www.kamailio.org/events/2017-AstriCon/

I expect that recordings of the sessions will become available in the near future from the organizers of Astricon.

During the breaks and evenings, I enjoyed amazing time with friends and kamailians around the world. It’s no time to bore with people such as James Body, Simon Woodhead, Susanne Bowen, David Duffett, Nir Simionovich, Lorenzo Miniero … and many others that I miss to remember at this moment…

Definitely it was one of the best AstriCon ever, credits to Digium and the organizing team! Kamailio had a great time there, see you at the next editions!

Thanks for flying Kamailio!

Development For Kamailio v5.1 Series Is Frozen

A short note to mark the freezing of development for Kamailio v5.1 series.

For few weeks, no new features will be pushed in the master branch. Once the branch 5.1 is created (expected to happen in 3-4 weeks from now), the master branch becomes again open for new feature. Meanwhile the focus is going to be on testing current code.

Work on related tools (e.g., kamctl) or documentation can still be done as well as getting the new modules in 5.1 in good shape, plus adding exports to kemi interface (which should not interfere with old code).

The entire testing phase is expected to be 4 to 6 weeks, then the release of v5.1.0 – likely by end of November should be out.

What is new in current master branch comparing with previous stable series (v5.0.x) will be collected at:

• https://www.kamailio.org/wiki/features/new-in-devel

Changes required to do the update from v5.0.x will be made available at:

• https://www.kamailio.org/wiki/install/upgrade/stable-to-devel

Helping with testing is always very appreciated, should you find any problem in current master branch, just open an issue on bug tracker from:

• https://github.com/kamailio/kamailio

Thanks for flying Kamailio!

Freezing Development For Kamailio v5.1

The development of new features for next major release, Kamailio v5.1, is going to be frozen on Monday, October 16, 2017. The master branch received plenty of new features since the release of v5.0, which was out by end of February 2017.

Next release will bring at least 7 new modules (although we are expecting one or more to make it in during next days). Not really up to date, the list of new features is collected in the wiki page at:

• https://www.kamailio.org/wiki/features/new-in-devel

After the freeze date, we start the testing phase, which is expected to last for 4 to 6 weeks, then we will have the first release in the 5.1 series, respectively the version 5.1.0.

Shall you have plans to include new features in v5.1, it is time to hurry up and have the commit or pull request ready by end of next Monday.

Thanks for flying Kamailio!

AstriCon 2017

Kamailio is going to be present at AstriCon 2017, the Asterisk User Conference and Exhibition organized by Digium, to take place in Orlando, FL, USA, during October 3-5, 2017.

Carsten Bock, Daniel-Constantin Mierla, Fred Posner and Jöran Vinzens will have presentations about Kamailio (see the schedule here). Besides the conference sessions, Kamailio project has a booth the expo area, be sure you stop by for a chat and some cool demos of using Kamailio alone or together with Asterisk.

We expect a consistent group of people from the Kamailio community, the event being a great chance to meet with many world wide friends, especially the North American kamailians.

Looking forward to meeting many of you in Orlando by beginning of October!

Thanks for flying Kamailio!

Next Kamailio IRC Devel Meeting

To sync properly for the next major release of Kamailio (v5.1.0) and ongoing development, we propose an IRC devel meeting for next week, on Wednesday, Sep 27, 2017. An alternative would be the following day, Sep 28, or if there are many devs that want to attend and cannot do it these days, we can look at another date. Just propose new day and time via sr-dev mailing list.

The meeting is going to be held as usual in the #kamailio channel on freenode.net IRC network.

A wiki page was created to collect the topics that are wanted to be discussed:

• https://www.kamailio.org/wiki/devel/irc-meetings/2017b

Fell free to add there or reply to the mailing list with what you think it is relevant to discuss.
