You’ll love ClueCon if…
You’re a new business startup or existing technical company looking to get development teams up to speed on the technology they need to succeed in VoIP and Telephony.
You’re a developer working with an open source VoIP project.
You’re someone who loves the idea of connecting computers to telephones.
You’re dealing with high-density telephony.
You’re interested in integrating conference calling and PSTN with HTML5 and WebRTC.
ClueCon is a conference for developers, by developers. An annual technology conference hosted by the team behind the FreeSWITCH open source project. Our primary focus is to gather various open source projects related to voice over IP, open source software and hardware, Telecommunications, WebRTC, and AI advancements. We sit at the intersection of communication and technology and we love all things technical. Open source projects that have been represented over the years include FreeSWITCH, Kamailio, Asterisk, OpenSIPS, FusionPBX, Janus, HOMER, and many more!
ClueCon was founded over a decade ago in 2005 by an aspiring team of Asterisk software developers who wanted to push the envelope, and set out to gather all of the open source projects into one place. They shared their wisdom and made open source communication a disruptive force in the industry. By the second year, that same team of developers, inspired by the first ClueCon, created a brand new open source communication application known today as FreeSWITCH. Every year 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 technology presentations that continue to inspire the way forward.
ClueCon offers something for everyone, from a software developer playing with new ideas to the CEO of a technology company looking to take advantage of real-time communication. We begin the week with the Coder Games, devoted to coding and building technology. The following three days are packed with presentations by technology leaders from around the world covering all aspects of WebRTC, IoT, and Telephony. The motto of ClueCon is “a conference for developers by developers.” We take that to heart, making sure we have a comfortable setting and lots of opportunities for networking and sharing ideas. ClueCon is like no other conference, so come join us this year and become part of the ClueCon family!
Are you interested in learning more about FreeSWITCH? Why not come meet the developers in person? In addition to all the other great activities, attending ClueCon is the best way to gain traction with FreeSWITCH! This year at ClueCon, in addition to several FreeSWITCH related presentations, we will also have a FreeSWITCH Round Table, hosted by the core FreeSWITCH team. This includes presentations, a Q&A on Packaging, Development and Deployment Strategies and more!

“The spirit of the conference, the people, the whole setup – it’s unique, it’s very special, and one of my favorite conferences.”
