About OpenSIPS Summit

Bridging people, bridging technologies, bridging experiences

OpenSIPS is one of the most used Open Source SIP Servers in the world. It's routing millions of calls across the globe each day. It has been 100% Open Source and has been backed by a robust community for over 15 years.

Back to the class - for the 8th edition, after 2 years of online editions, the community decided for the beautiful city of Athens as a place to engage and learn about all the newest developments in OpenSIPS. Although the lineup of speakers and topics change with each year, all those attending walk away having captured important knowledge and insight into how OpenSIPS can be, and is being, used in some of the top companies in UCaaS and RTC. Experiencing first hand presentations on complex end-user deployments, high throughput infrastructure components, and the latest improvements to OpenSIPS is undoubtedly a "can't miss" experience for employees of carriers, telcos or ITSPs.

The OpenSIPS community is full of experts, developers, VoIP architects, and pioneers from all over the world! These same people are not only looking to share their knowledge with attendees, but also learn and gain knowledge from them as well. As an attendee, you can expect a melting pot of discussions ranging from new & emerging technology to sharing real world experiences and brainstorming on new trends. It is THE place for building bridges in the Open-Source VoIP & RTC ecosystem.

As the popularity of OpenSIPS grows and it becomes a de facto part of deployments, you will find conference attendees are drawn from many areas of business both technical and non-technical. They include CTOs, Lead Engineers and Technical decision makers from small, medium and large enterprises, corporations and organizations worldwide.

Their topics are not OpenSIPS centric, but also tackling other softwares, projects or technologies. After all conferencing session is a massive knowledge transfer, in terms of news, experience and solutions, from speakers to audience.

Frequently Asked Questions

I'm not a Developer. Is this for me?
Absolutely! Our conference is based on technical and telecom subjects, but with its absolutely laid back atmosphere it attempts to bring together and aggregate newcomers, intermediates and experts to exchange experience. Some developers will come to network, while other participants come to learn and we make sure there's always something for everyone.
Quite the opposite! Everyone is welcome at the Summit to learn, teach or exchange their experiences. Our content will provide you with plenty of reasoning, use-cases technical and otherwise, and material to learn more about OpenSIPS and its key features and strengths. Be warned though, as you might make a few friends in the process!
