ClueCon 2019 – 15 Years Challenge

What is ClueCon?

ClueCon is a conference for developers by developers: an annual technology conference held every summer for the last 14 years, hosted by the team behind the FreeSWITCH open source project. Our primary focus is to gather various open source projects to discuss WebRTC, VoIP, open-source software, telecommunications, AI and IoT. We sit at the intersection of communication and technology and we’re passionate about all things technical. We love to learn and we love to have fun; our conference truly is for developers by developers. The event takes place in Chicago, IL, USA,  5th – 8th of August, 2019.

We’ve celebrated many open source projects over the years, including Kamailio, FreeSWITCH, Asterisk, FusionPBX and many more! Kamailio is often represented at ClueCon and works closely with FreeSWITCH as a critical part that allows you to route sip messages to FreeSWITCH or multiple FreeSWITCH instances. In fact, You can see Daniel-Constantin Mierla, co-founder of Kamailio, speak at ClueCon this year! He will be speaking on versatile SIP routing with Kamailio embedded scripting languages.

He says that “nowadays an RTC platform is no longer only about dispatching SIP packets between telephones. Integration with orchestrations tools, cloud and container technologies, or interaction with external systems play a key role for scalability, reliability and innovation.” He will “highlight the powerful embedded scripting framework available now in Kamailio, enabling use of Lua, Python, JavaScript or Ruby for even more flexibility and rapid development of new VoIP services, while preserving the same high capacity of SIP messages processing and routing.”

Fred Posner is also presenting about why using Kamailio in large VoIP deployments. You can learn more about ClueCon here and save $500 on registration using the special code: OPENSOURCE

ClueCon 15 years ago:

Which came first: the chicken or the egg? ClueCon or FreeSWITCH? In this case, ClueCon takes the cake starting one year before FreeSWITCH was publicly released. ClueCon was founded way back in the good old days of 2005, by an aspiring team of Asterisk software developers who wanted to push the envelope. Their quest was to gather all of the open source projects into one place. Before ClueCon, there was no conference that covered everything about open source telephony, so their event created an opportunity for many different projects to come together and share what they were up to.

Many people from around the world attended the first ClueCon talking everything telephony and enjoying the chance to bounce crazy ideas off of each other. From these conversations, the team figured out what they needed to do to get FreeSWITCH really going and it was finally presented to the public at the second annual ClueCon! ClueCon started rolling after this, and it only evolved over time.

We would be lying if we said that everything about our first conference was perfect, but it definitely had a lot of character! The team had never organized a large event before but they did their best to create an environment that was fun and packed full of industry knowledge. The first ClueCon wasn’t flashy but it was certainly a success (someone even brought a keg and it stayed right in the middle of the conference room all week!) While our conference has certainly evolved, we still carry that same sense of character and family from the first conference with us today.

ClueCon Today:

We are so excited to celebrate our 15th ClueCon anniversary! Our quindecennial if you will. While we started our focus on open source telephony and VoIP 15 years ago, we’ve now evolved into adding WebRTC, IoT, maker, SignalWire, and everything else cool about doing development to the discussion. Every year for 15 years, the core members of the FreeSWITCH team still produce and oversee the conference with the original goal in mind: to blend a diverse collection of open source projects, speakers and technological presentations that continue to inspire the way forward.

ClueCon is a place for discovery, development and expansion and our audience has only grown since we started. You’ll find everyone from one man companies figuring out how to make something out of the technology they have, to CEOs and big sponsors that use open source, and all the way to venture capitalist groups. That’s the joy of ClueCon: everyone comes together to collaborate. We’ve created a space for developers to work through problems together and to share the projects they are passionate about.

Our attendees have told us our conference is like taking a college course all in one week – learning a lot during the day and socializing a lot in the evening. We love to have FUN and nobody knows developers like we do! We’ve even added a popular hack-a-thon event (the CoderGames) that challenges our attendees to techie and not so techie games.

We like to think that we’ve carried the original vision of ClueCon throughout the years and only made it better. Of course, we don’t put on the conference for ourselves, we do it for you, so feel free to let us know what you’d love to see done in the future on our slack channel at! If you’re interested in registering for ClueCon, you can do so here at the lowest price we’ve ever had at $799!

We won’t have keg sitting in the middle of someone’s talk…but we will have an open bar at the Gigabit Reception on Tuesday!
