The dream of every aspiring VoIP / WebRTC / Telecom Engineer is “to get a clue.” Getting a clue never comes easy and takes years of hard work and dedication. For over 15 years the ClueCon Technology Developers Conference has been dedicated to helping the FreeSWITCH team and other software engineers “get a clue.”

ClueCon is where it all began. The idea of FreeSWITCH was thought up at the first ClueCon in 2005; the plan was born based on the ideas that were bounced around during that first 3 day conference. The core members of the team worked hard for the next 12 months, and FreeSWITCH was presented for the first time at ClueCon 2006.

The ClueCon conference was started in 2005 and over the years has grown with help from our sponsors, attendees and the members of the open-source community. Previously, ClueCon has been held in Chicago, Illinois, the hub for the annual conference, taking advantage of the many first-rate hotels that the city has to offer. Due to COVID-19, ClueCon has moved our 2020 conference entirely digital.

Coder Games:

The Coder Games are ClueCon’s version of a hackathon with a few surprises thrown in. We invite our attendees to participate in several fun challenges for people of all technical skills. The Coder Games are a great way to meet people in a relaxed environment: try your hand at building popsicle stick contraptions or dig into some API’s!

Yes, anyone who is attending ClueCon can sign up for the Coder Games.

We encourage all forms of participation! Feel free to park in the Coder Games virtual room and observe, assist, eat a snack, or get some work done. We also have a few demo events which are always fun to watch.

We encourage everyone to participate  in the Coder Games and do not have an official registration: just hop in and participate! You can either speak with a team leader for help, or follow the written instructions on the table. When you submit a challenge to the judges you are officially eligible to win a prize. However, when you register for ClueCon, it is helpful to check whether or not you will be attending the Coder Games so that we can better plan for the event.

You can participate in as many or as few challenges as your heart desires. You can even combine challenges to receive a super secret bonus prize.

We accept solo entries as well as teams of all sizes. If you need help finding a teammate, contact a team leader and they will help find you a partner.

We provide a plethora of materials to work with, but it’s not against the rules to Amazon Prime a thing or two.
