OpenSIPS 2.3 version is built around the integration concept - the OpenSIPS ability to integrate and work together in all possible means with other projects, protocols, systems or concepts. Understanding the integration capabilities of OpenSIPS 2.3 will unveil a powerful tool for building SIP systems.

Presented by Bogdan-Andrei Iancu OpenSIPS Project
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
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 Project
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 Project
Veteran entrepreneur Suzanne Bowen and veteran developer Bogdan Iancu share POVs, stories and advice on Accessibility, Community, Opportunity, Profitability, and Scalability in relation to communications technology past, present and future. Interactivity among participants will be welcome.

Presented by Suzanne Bowen & Bogdan-Andrei Iancu DIDX.NET
Migrating a telephone system based on 16 stations Ericsson MD110 to VoIP has not been easy. There are services to deploy, feature to replicate and, above all, be able to make co-operate two networks based on different technologies without creating inefficiencies. I would just tell you how I did it.

Presented by Michele Pinassi UNISI
At Jitsi, we believe every video chat should look and sound amazing, between two people or 200. Whether you want to build your own massively multi-user video conference client, or use ours, all our tools are 100% free, open source, and WebRTC compatible. In this presentation we'll dive into how Jitsi Meet works and how we bridged the gap with SIP video devices, in a really innovative way.

Presented by Saúl Ibarra Corretgé Atlassian
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 William King Flowroute
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.

Presented by Lorenzo Miniero Meetecho
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.

Prensented by Jöran Vinzens SIPGATE
Growing your FreeSWITCH platform beyond the single machine: differences between single domain case and multi tenant case.

Presented by Giovanni Maruzzelli OpenTelecom
Talk about mediasoup, a powerful WebRTC SFU for Node.js. Live demo included.

Presented by Iñaki Baz Castillo Mediasoup
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.
    Our small army of demo gurus will show you:
  • Deploying a full WebRTC solution with OpenSIPS
  • Adding Homer Capturing for OpenSIPS
  • Using CGRates to rate your calls
  • Improving Balancing to a FreeSWITCH cluster
  • Implementing Push Notification with OpenSIPS
  • Enabling Fraud Detection for your customers
A one day training focused on OpenSIPS frontending for a FreeSWITCH cluster. Starting from a basic configuration, the training will walk you and teach you how to address certain aspects related to frontending a Class5 FS cluster with OpenSIPS:
  • performing mid-registration on OpenSIPS
  • load-balancing calls to FreeSWITCH with realtime load feedback
  • perform fault detection and re-routing for the FreeSWITCH cluster
  • handling special cases as Call Transfer or Conferencing
  • routing outbound calls to carrier (with failover)
  • monitoring and tracing with Homer
  • Students are required to bring their own laptop - as work material, they will receive a virtual machine holding the setup, ready to be used.
