A Guide to ClueCon’s Evening Events

ClueCon has a lot going on every day: educational presentations, workshops, hands-on hack-a-thon challenges. So each night of the conference, we’ve carved out time for networking and fun to unwind, relax, and get to know your peers.

After a long day of presentations or building engineering marvels, join the FreeSWITCH founders, the developers who maintain the project, the ClueCon team, and others in the community for some food, drinks, and games. 

When you’re purchasing your ClueCon tickets and wondering whether to check ‘yes’ or ‘no’ on your sign up form for each evening event, this guide will give you some insight on what exactly those events are. Here’s a brief overview of the 2022 evening activities for you to consider when registering for this year’s conference.

Monday Night: Dinner at Melnick’s

We start the week off easy. After a day of hacking and building at the Coder Games, we’re off site from the hotel for a classic Chicago dinner at Jake Melnick’s Corner Tap. Join us for an evening of Chicago wings, barbecue, and drinks. We’ll spend a couple of hours enjoying some good food, good company, and relaxing before the week to come. Who knows? We might even keep the festivities going after dinner.

Tuesday Night: The Gigabit Reception

Every year, the Gigabit Reception is high energy and highly anticipated. This is our annual party where everyone has the chance to get together and mingle with all the other attendees, speakers, and sponsors, and we wouldn’t recommend missing it. With Halloween just around the corner, we even added a costume party to this year’s event! There will be food, there will be drinks, there will be games, and there will be music. Bring your favorite instrument, because the annual Jam Session always features Anthony Minessale on guitar and any other willing musicians who want to join. And if you aren’t a particularly skilled musician, don’t worry…  ClueCon karaoke will feature the rest of us who just want to have a good time.

Wednesday Night: Poker Night

Last year we hosted our first ever ClueCon Poker Night, and it was such a success that we’re bringing it back around for a second time. The tournament will be sponsored by and World Poker Tour Champion Phil Gordon. Let your competitive side out a little! If you haven’t played much poker before, don’t worry – this event is beginner-friendly. Anybody could be the winner. Flex your poker skills or just enjoy some drinks and watch the drama unfold. If you win a game, you might even get some cool prizes.

We hope to see you there!

ClueCon 2021 Wrap-up

Thank you to everyone who attended ClueCon TGI2021, our first hybrid ClueCon! Whether you attended in person or online, we appreciate you joining us for this hybrid event experiment. This new format allowed for those attending online to interact with those in person and vice versa, which was a ClueCon first. If you have any feedback about your experience, you can fill out this quick survey to share it with us so we can make ClueCon even better next year. Though the format was a little different this year, ClueCon followed its traditional lineup of events throughout the week. Monday kicked off with the Coder Games, our annual hack-a-thon that includes several challenges for developers and non-developers alike. Attendees built boats, engineered bridges, and played trivia with virtual attendees to win an exciting array of prizes.
A beautiful boat styled as a chariot.
The presentations started on Tuesday after the release of FreeSWITCH v1.10.7! In FreeSWITCH founder Anthony Minessale’s keynote, he addressed how we made the hybrid event happen by using the video technology built over the years on the back of FreeSWITCH, and how we try to make life easier for developers, including the devotion to open source that fuels ClueCon each year. Videos of all the ClueCon presentations and workshops will be available soon – subscribe to the FreeSWITCH YouTube channel so you don’t miss out! The annual Gigabit Reception took place Tuesday evening as well, but this year, with a spooky twist! After a long day of presentations, attendees put on their Halloween costumes, grabbed their favorite drinks, sang karaoke, and played games. Virtual attendees were able to pop in and hang out with us in the lounge too!

Wednesday included more presentations, a Kamailio workshop led by Daniel-Constantin Mierla, some seriously Dangerous Demos, and a FreeSWITCH roundtable until the evening, when attendees participated in a poker tournament thanks to the sponsorship of Phil Gordon and The week wrapped up on Thursday with a few more presentations, a HOMER workshop led by Lorenzo Mangani, and our Grand Prize giveaway of a custom engraved MacBook Pro.

We want to give a warm thank you to all our sponsors and speakers who made ClueCon possible in what was a difficult and uncertain year. With social distancing measures in place, like our bigger venue with spaced out seating, and the option to attend online, we hoped to keep everyone comfortable and safe as we reconnected with the FreeSWITCH community. Overall, this ClueCon was a successful first hybrid event and we had a ton of fun getting back together in person at last. If you miss ClueCon like we do, or you’re suffering from moderate to severe FOMO, consider joining us October 17th-20th in 2022!

4. The Gigabit Reception

Most conferences worth their salt have a reception – a chance for the attendees that make up the community to mingle. The Gigabit Reception is the annual party that happens on Tuesday evening during ClueCon. This is one of my favorite events. After a long day of absorbing the vast knowledge that the speakers will share, partaking in prize drawings (at least 3-4 each day!), stuffing yourself with a delicious Chicago lunch and visiting with our amazing sponsors, it’s always great to relax, listen to music, play video games, and unwind.

This year will be one of the most amazing receptions of all time. Equal to the Met Gala in grandeur, the who’s who of ClueCon and FreeSWITCH will dazzle you with their presence. With Halloween just around the corner, we even added a costume party to the event. There will be a little bit of something for everybody – board games, drinks, hors d’oeuvres, and more.

The most exciting parts of the Gigabit Reception are the Mario Kart tournament, karaoke, and Anthony Minessale’s annual guitar jam session. Whether you’re joining us in person or online this year, you can hang out with fellow community members, jam out, wear a costume, and have a blast at this highly-anticipated networking event!

3. Registration

The registration desk holds a special place in my heart. I first came to ClueCon to hang out with a friend, knowing nothing about open source telecom, and was asked to help out on the first day of the conference. It was love at first sight. The small area that was made up of a metric ton of cardboard boxes was transformed into the beautiful check-in setup that is the first impression for each attendee upon arrival.

Working at the registration desk is fast paced and busy those first couple days, but the best thing about it is meeting all of the attendees we will be spending time with that week, and revisiting with all of the attendees who come back year after year. ClueCon attendees are the glue that holds ClueCon together and they are the reason we have a conference every year. Without them there would be no ClueCon!

When you get off the elevator, you will immediately be surrounded by fellow community members, and have the chance to mingle at the meet and greet at registration. This year we will also have color-coded lanyards you can use to indicate your comfort level for social distancing practices. And of course, there will be plenty of masks and hand sanitizer available to keep everyone safe and healthy.

2. Meet the Creators of FreeSWITCH and the Founders of Cluecon

Anthony Minessale, Brian West, and Michael Jerris are the brilliant minds behind the FreeSWITCH open source project. I have grown very fond of these three. They saw a need in the world, and they set out to fill that need – while making it free to everyone. This mission that led to the creation of FreeSWITCH will always be at the heart of ClueCon.

The three of them met a few years before the first ClueCon, and it was the first ClueCon that would lead to the founding of FreeSWITCH itself. Unlike today’s videoconferencing-centric world, back then humans were drawn to meeting in person. In 2005, they hosted the very first ClueCon, and instead of a well-organized tech conference, it was more like inviting 50 friends to get together. Located at the Best Western near the airport in Chicago, it was not nearly as lavish as it is today. The traditional nightly activities were the same, although the parties included kegs they could not finish (but hey, bonus beer during the conference the next morning… I don’t know if it was a good idea. But I’m sure it was fun.)

Come to ClueCon and meet the founders! When you do, ask them about the SWAT team at the first ClueCon. Stories galore!

1. A chance to see my Binders in person… You never even realized this was missing from your life.

I can go on for hours about all the details that go into planning a ClueCon. From all the logistical organizing with the hotel, to minutiae like labeling the raffle tickets, to drafting schedule after schedule, the almighty binder contains all the information we need to survive the week. Over the years we have learned that not all hotels have the immense capacity for internet that we need; that not all hotels can produce the audio and video levels that we need; that during a global pandemic it is important to have a great virtual platform to use to integrate those who can’t be with us in person. So we have used our own technology and resources to accomplish all of this and more.

These endless details cannot be kept in any one person’s head, so I have about 20 lovely binders that keep all of ClueCon safe in the hands of all the organizers. These binders are my brain and without them I dont think ClueCon would be as successful as it is. Yes, I said it: the binders are the single most important aspect of running a great conference. They help run the conference like a well-oiled machine.

I might have said it before about attendees… but binders are the glue holding ClueCon together.
