Kamailio Development Workshop, July 9-10, 2014, Paris, France

Want to learn more about the inside of Kamailio? Next Kamailio Development Workshop takes place in Paris, France, during July 9-10, 2014.

The coordinator of the workshop is Daniel-Constantin Mierla, co-founder of Kamailio project, the entire event being organized by Asipto, Germany and Orange, France.

The goal of the event is to present how to write your own extension in C code for Kamailio SIP Server. Note that it is not a training for VoIP administrators looking to learn how to configure and operate Kamailio-based SIP-VoIP platforms.

During the two days in the workshop, following topics will be approached:

• internal architecture
• SIP parser
• memory manager
• locking manager
• database API
• config file language interpreter
• RPC interface
• pseudo-variables and transformations framework
• internal libraries
• module interface – write your own extensions in C as modules
• documentation docbook format

In other words, main outcome of the workshop is developing on site a sample module that exports new parameters, functions, RPC commands, pseudo-variables, deals with locks, private and shared memory, accesses SIP message attributes and updates SIP message content, a.s.o.

The price per attendee is 240 Euro.

Number of seats to the workshop is limited and access will be granted in first come first served fashion. Registrations or requests for more details has to be done via email at:

registration [at] kamailio.org

A social networking dinner is planned for the evening of July 9, open for everyone willing to join, no matter of participation to the workshop. More details about this event will be published in the near future.

Kamailio 2013 Awards

Here we are, the 7th edition of Kamailio Awards granted for the activity during the previous year, respectively 2013. The ceremony follows the same rule, two winners per category.

With two major releases across 2013, respectively v4.0.x and v4.1.x, and having our first dedicated conference for Kamailio project, making the decisions for these awards was harder than ever so far.

Ladies and gentlemen, next are the categories and the winners!

Blogging

• Kristian Kielhofner - blog.krisk.org - a veteran in VoIP, with consistent activity over the years in Asterisk, FreeSwitch and Kamailio, Kristian wrote many good technical articles, even inspiring the development of gzcompress module in Kamailio
• Jose Luis Verdeguer - blog.pepelux.org - (Spanish) a comprehensive tutorial about creating a SIP honeypot with Kamailio. Jose is involved in securecall.org, a project aiming to provide a service for secure communications

Related Projects

• baresip - an open source, bsd licenses, full SIP stack and soft phone, able to handle signalling over IPv4/IPv6 UDP, TCP and TLS, with support for ICE, TURN as well as audio and video. The project is developed by Alfred E. Heggestad, who did many contributions to SER and Kamailio over the time
• lumicall - an open source Android softphone targeting to provide similar experience to proprietary Viber service, using your own SIP server or the one hosted by the project. The main developer is Daniel Pocock, a person with vast activity in open source real time communication projects and a promotor of Kamailio

Technical Support

• Daniel Tryba (pocos.nl) - very active on mailing lists, he has been assisting many people to sort out SIP routing issues with Kamailio
• Vitaliy Aleksandrov (wildix.com) - involved in users and developer forums, he provided many patches approaching quite complex corner cases for TCP and WebSocket extensions

New Contributions

• rtpproxy-ng - by Richard Fuchs (sipwise.com) - the new generation of the module controlling the RTP relay application, typically used for NAT traversal. The control protocol reuses bencode format, allowing to extend it easier. The main target is usage together with mediaproxy-ng from Sipwise, a replacement for old RTPProxy, which also has the capability of encrypting/decrypting RTP streams to allow classic SIP phones to communicated with WebRTP endpoints (afaik, SDES implemented (but deprecated by IETF, still supported by some versions of web browsers) and DTLS on the way)
• mohqueue - by Robert Boisvert - rather interesting new module, allowing to use Kamailio for building call queues. A media server is needed only for playing music on hold, Kamailio taking care of queue management. Now your turn to build thousands of queues and blog about!

Developer Remarks

• Camille Oudot, Orange France - he joined the development team, helping to improve and maintain the large set of IMS related modules
• Victor Seva, Sipwise, Austria - one of the most active developers during past years, touching various areas such as core, debugger, app_lua, registrar and usrloc, documentation and packaging

Advocating

• Alan Duric - on of the pioneers in VoIP and co-founder of Telio in Norway, involved in many ventures related to real time communications, Alan was supporting and using our project from the early years of SIP Express Router
• Victor Pascual Avila - involved quite a lot in standardisation groups, Victor keeps referring to Kamailio for many new specifications we have implemented, such as SIP over WebSocket for WebRTC, at the events he participate across the world and via webrtchacks.com blog

Products and Services

• Bezeq - the main telecom company in Israel - if you ever thought that Kamailio has limitations on what one can do with it, approach Uri Shacked from Bezeq and see how he designed an IVR system using Asterisk as simple DTMF detector and Kamailio doing the business logic for the IVR menu
• Voxbone - the international DID provider based in Belgium - had the courtesy of contributing back to Kamailio project the module for handing SIP-I/SIP-T message, via Torrey Searle who became a registered developer of our project

Business Initiatives

• Gonicus, Germany - gonicus.de - a company focusing on using open source technologies, deploying IP telephony systems to large enterprises
• 2600hz, USA - 2600hz.com - offering a hosted PBX service relying on Kazoo platform (which combines Kamailio and FreeSwitch), recently including mobile network integration, thus a straightforward way to become MVNO in USA

Events

• AstriCon - celebrating 10 years of existence, AstriCon 2013 gave the chance for many Kamailio developers and users to meet last autumn in Atlanta. It was really a great show, with presentations related to Kamailio from Peter Dunkley, Klaus Darilion and Daniel-Constantin Mierla (aka me), surrounded by friends such as Fred Posner, Alex Balashov, Olle E. Johansson, Torrey Searle, Randy Resnick and the entire Asterisk crew
• Kamailio World - it was our first edition of a dedicated event for Kamailio project, touching technical aspects and the business environment around it. With participants from across 5 continents, our expectations were exceeded and we are looking forward to the second edition to happen soon in Berlin, during April 2-4, an edition already with more confirmed participants and content

Academic Environment

• University of the Aegean, Karlovassi, Greece - www.aegean.gr - involving Kamailio in academic activities, such as the article A Privacy-Preserving Entropy-Driven Framework for Tracing DoS Attacks in VoIP (pdf), presented at International Conference on Availability, Reliability and Security (ARES Conference)
• University of Florida, Gainesville - www.ufl.edu - involving Kamailio in academic activities, such as the article A Distributed IP-Based Telecommunication System Using SIP, published in International Journal of Computer Networks & Communications

Friends of Kamailio

• Dan York - with a long record related to VoIP security, he does and extensive work at Internet Society in promoting new, better and more secure technologies for real time communications, such as IPv6, TLS/encryption, DNSSec. Dan constantly advertised Kamailio at world wide events and online articles about implementations of those specifications .
• David Duffett - running Telespeak UK and acting as Community Manager for Asterisk, David has been always highlighting the benefits of using Kamailio and Asterisk together as complement applications to get the best of what can be deployed for specific needs of large real time communication platforms.

Definitely 2013 wasn't with bad luck for Kamailio at all and 2014 looks very well so far -- keep an eye on the project for getting latest news and updates on development and events world wide where you have have the chance to meet other kamailians.

This is it for 2013. If you want to check the previous turn of awards, visit:
