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
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
