LeanDUS at sipgate, May 26, 2015

May 19th, 2015

sipgate, one of the oldest supporters of SER/Kamailio project, with Marcus Hunger member of project’s management team, is hosting the LeanDUS meetup on the evening of May 26, 2015, an event free to attend. Special guest is Matt Jordan, the lead developer of Asterisk Project.

Many sipgate VoIP engineers will attend the event, like Marcus or Sebastian Damm, therefore you can get more details about how Kamailio is used for their VoIP service.

Sebastian comes also to Kamailio World Conference to talk about SIP and IPv6, how to use Kamailio to build a VoIP bridge between IPv4 and IPv4. Matt Jordan will be also in Berlin to give the latest updates about Asterisk project.

New Module: Erlang

May 11th, 2015

Before freezing the development for next major release – Kamailio v4.3.0 – several modules and other relevant additions were pushed in a rather short period of time to git repository. Now, we are trying to look briefly at few of them in a series of posts in order to let everyone know about them.

First to talk about it is the erlang module, contributed by Seudin Kasumovic of Bicom Systems. Erlang is a functional programming language tightly related to telecom environment, with built-in support for concurrency, distribution and fault tolerance

The module enables interaction of Kamailio with Erlang nodes, allowing to send and receive Erlang messages as well as RPC calls between each other. You can read more about it at:

Seudin will also present at Kamailio World Conference how this module can be used and its benefits for scalability and reliability.

Kamailio v4.3 – Development Frozen

April 23rd, 2015

Kamailio Development NewsThe development (aka master) branch of Kamailio now enter the pre-release phase for version 4.3.0. No new features are allowed to be pushed to GIT master branch until we create a dedicated branch for 4.3 (expected to be in about 4 weeks or so).

The focus moves now on testing the code, to get it in a stable, rock solid state at the time of release. We hope to get many people from the community involved in testing. If you want to get involved and need assistance about what and how to do it, please don’t hesitate to write to mailing lists. The first step is to get Kamailio installed from sources, details at:

Stay tuned for updates to the wiki pages with guidelines for migration from 4.2 to 4.3 as well as what is new in version 4.3.

The release of v4.3.0 is expected to be out few weeks after Kamailio World Conference — more or less about mid of June 2015.

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!

Secure your participation and register now!

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!
