Presented by Nikola Pachedzhiev ZOIPER
Introducing the HEPIC stack.

Presented by Lorenzo Mangani QXIP/SIPCAPTURE
Exploring the capturing capabilities of OpenSIPS 2.3 in terms of non-SIP traffic with Homer6 - collecting data from transport layer (TLS/WSS), from REST query level, from Management Interface level. A complex set of data, with the ability of correlating all the information around the SIP calls, that proves to be a holly grail when comes to operating and troubleshooting SIP platforms.

Presented by Ionut Ionita OpenSIPS
Unlike other industries, the VoIP and RTC ecosystem lacks an accessible network for threat intelligence, leaving many Operators on their own reinventing the security wheel. It’s time for our Community to secure itself with a real-time trusted, voluntary, federated Pub/Sub Exchange, instantly exposing Attackers, Abusers and new Threats, acting as an open and distributed Lock natively integrated at the core of our favorite stacks.

Presented by Alexandr Dubovikov QXIP/SIPCAPTURE
SIP-I trunks are the cost effective replacements for the traditional SS7 interconnections. And now, OpenSIPS 2.3 helps in integrating the SIP-I trunks with the end-user devices by performing the SIP-I to SIP conversion and ISUP manipulation.

Presented by Razvan Crainea OpenSIPS
We are still using ISUP for our interconnect to several carriers and providers. Unfortunately we depended on log files for debugging. For all of our SIP traffic we use homer for debugging and monitoring so we knew there is a better way. Thanks to the integration of ISUP into homer we now have a single debugging and tracing tool for our developers and customer support. In my talk I'll give an overview of how it looks and how we use it.
Presented by Jöran Vinzens SIPGATE
An interactive guide to configuring the latest version of OpenSIPS to allow you to make WebRTC based calls.
Presented by Peter Kelly SourceVOX

Together with it’s 2.3 release, OpenSIPS introduces integration for CGRateS processing directly within OpenSIPS script, thus simplifying a task which for long was considered as “last mile” - billing for SIP proxied requests. In this talk Dan will reveal details regarding integration mechanism as well as discussing advanced use cases available now directly in your OpenSIPS scripts. CGRateS is a battle-tested Online Charging System with support for both prepaid and postpaid billing modes.
Presented by Dan Christian Bogos CGrates

The Round Tables are open discussions around given topics - usually new or interesting subjects . Each tables has its own topic and the discussion is moderated by a person with advance knowledge and experience on the topic. People should join to a Round Table either to share, either to learn the latest news and tricks on the discussed topic. Such discussion are a real melting pot of the real-life experiences.
    Available topics :
  • OpenSIPS as SBC
  • WebRTC
  • SIP Security
  • SIP-I integration
  • Front-ending to Class5 clusters
  • Capturing with Homer
  • CDR handling
Interesting ideas must be backed up by practices - the Interactive Demos are 100% practical lessons, in from of the monitors, on how to installed, configure and run certain setups. Everything is A to Z explained and then shown in realtime, to the audience. Why is it interactive? The participants will have the opportunity to see for real how things are done, they can ask questions and debate aspects related to the demo case.

How to achieve accurate load balancing and optimal resource usage when routing calls over a cluster of FreeSWITCH servers. The key is to get access to realtime feedback from FreeSWTICH to understand the full load context of it, in terms of channels and CPU usage.
Presented by Liviu Chircu OpenSIPS Project
In the realm of real time communications and messaging, what are some of the attributes of a modern software stack? From the perspective of a telecommunications operator and US CLEC, this presentation will cover topics such as containerization, test-driven development, continuous integration plus deployment, logging and introspection, service registry and discovery, and load testing, and how these minimize dev-ops response latencies. Understanding the problems addressed strategically by a modern software stack provides the foundations for building tactical responses to dev-ops challenges.

Presented by Iñaki Baz Castillo
Janus is an open source, general purpose, WebRTC server. It was conceived as a modular architecture, and different plugins can implement a different logic on the WebRTC media it manages. While so far only a single plugin existed to handle SIP gatewaying, based on the Sofia library, two new plugins are in the works to provide the same functionality in different ways and for different needs. This talk will address the different approaches that can be followed to have WebRTC and SIP co-exist, depending on the developers' requirements.
