With this sessions I am aiming to share some of my experiences and couple of nice tricks, which hopefully would be interesting and useful to the community, especially for new comers, but not only. They can be directly related to technical aspects of building VoIP systems with Kamailio and RTPEngine, such as SBCes, or to the social side of the open source community interactions. |
| 15:30-16:00 ♦ Coffee Break |
| 16:00-16:30 ♦ What The Fuzz! Or Why You Should Really Fuzz Your RTC Code |
| Lorenzo Miniero, Co-Founder Meetecho, Italy |
| In the past few months, fuzzing has become a hot topic within the context of RTC projects. In fact, while in principle this is not strictly speaking a new or innovative approach (past Kamailio editions, and the latest one in particular, have already been home to some excellent talks on SIP fuzzing, for instance), its application to RTC projects, and WebRTC in particular, has always been limited up until very recently, when a blog post on Google’s Project Zero highlighted several key vulnerabilities in known and widespread multimedia applications. This sparked the interest, among WebRTC developers, on fuzzing their applications as well. Considering how complex the whole suite of WebRTC protocols is (ICE, DTLS, SRTP, RTP/RTCP, data channels, and even codec-specific payload access), there are several aspects that go beyond pure signalling and require dedicated considerations.
This talk will address some of the efforts most projects have taken in that direction, with a few additional details on how we tackled that in our Janus WebRTC server in particular. It will describe the process we followed with practical examples, and how we applied the same concepts to different protocols (RTP, RTCP, codec-specific payloads and SDP in particular) in order to make the implementation as robust as possible. Some considerations will also be provided on the steps we took to integrate fuzzing as part of the whole development process, on other fuzzing techniques that might be used, and on how this pattern could be deployed in existing scalable infrastructures to execute tests in a distributed way thanks to frameworks like OSS-Fuzz. |

| 13:30-14:00 ♦ Voice Over RTP != Video Over RTP |
| Tim Panton, CTO at |pipe|, UK |
| Many in the audience come from a VoIP (where V=Voice) background. Users however expect Video in their services and whilst both use the (S)RTP protocol on the wire, there are huge practical differences between carrying voice and video. This talk describes the painful lessons I learnt when adding WebRTC Video to an existing technology stack. Hopefully this will make the transition easier for others. There will (of course) be demos and droids. |
| 14:00-14:30 ♦ Advanced SIP: Communicating With Humans |
| Fred Posner, Owner The Palner Group, USA |

| 14:30-15:00 ♦ Building Your New Native Softphone With Web Technologies |
| Dan Jenkins, Founder of Nimble Ape, UK |
| Building native apps is a costly business; both in development time as well as developer costs. Web oriented web developers cost less than “pure” native developers for many reasons – but modern day web development techniques allow us to move super fast in development cycles. Want a new custom softphone for your VoIP business and don’t want to white-label an existing solution? Then you’re stuck building something that can handle all of Android and iOS’s nuances with integration into iOS’s CallKit and Android’s Connection Service as well as giving the user the best quality audio and call set up times experienced. The answer is to build your native app with Web Technologies using WebRTC and all of the libraries that bridge the gap between Web and Native. I’ll show you how those two worlds join and some of the things we have to think about. |
| 15:00-15:30 ♦ Designing A Scalable Billing System Using Blockchain Technology |

| 17:00-17:30 ♦ Making Kamailio More Inclusive And Easier To Adopt |
| Mack Hendricks, Founder dSIPRouter Project, USA |
| When the work on dSIPRouter started, the goal was (and still is) to create a UI that would make installing and configuring Kamailio much easier. We wanted to provide a prescriptive way to use Kamailio and as people became more comfortable they would use the Kamailio.cfg file we provide as a basis to create more sophisticated use cases or they would move to using Kamailio directly. In this session, I will give your an overview of the dSIPRouter project and walk you thru how people are learning Kamailio using this project and how carriers are using this project to help expedite scaling out their environment. |
| 17:30-17:55 ♦ Replication Mechanisms For Multi-Node Kamailio Platforms |
| Daniel-Constantin Mierla, Co-Founder Kamailio, Germany |
| Kamailio offers several mechanisms to replicate data and states between different nodes in a VoIP platform. One can choose from low lever TM based replication functions, to PubSub architecture, database layer mirroring or going with the all-in-one solution DMQ (distributed message queue) with node auto discovery. This presentation shows all of them, when one suits better than the others and what are the aspects to be taken in consideration for various use cases, such as replication for user location, active calls or in memory hash tables. |
| 17:55-18:00 ♦ End of Event – Closing Remarks |
