Getting started with SIP Express Media Server SIP app server and SBC - workshopstefansayer
How to configure a SEMS instance for offering common media services such as announcements, voicemail, audio conferencing and IVR menus, and how to use the powerful and flexible SBC application, the "Swiss Army Knife of call stateful SIP processing".
A quick introduction to Kamailio - the leading Open Source SIP server (based on OpenSER and SER). Kamailio is quite different than Asterisk, FreeSwitch and many other VoIP platforms - why is that and how do you start getting your head around Kamailio?
Presentation done at Kamailio World 2014, Berlin, Germanu - several methods to do asynchronous SIP routing via Kamailio configuration file. Blend modules such as tm, tmx, mqueue, rtimer, async, evapi, etc. to suspend routing of current SIP request and resume that once processing of additional tasks has finished.
Homer - Workshop at Kamailio World 2017Giacomo Vacca
Homer is an Open Source tool for real-time analysis and monitoring of VoIP and RTC platforms. It supports all the major OSS voice platforms, it's modular, easy to install and scales to carrier-grade infrastructures. Homer goes beyond collecting and correlating signalling and logs, and can also capture RTCP reports, QoS reports, and other events. Through an ElasticSearch endpoint, Homer supports BigData analysis of traffic.
This workshop focuses on the deployment of a multi-node Homer framework with various approaches: bash installers, Docker containers, Puppet.
We'll see how to configure Kamailio, FreeSWITCH (including the ESL interface), RTPEngine, Janus gateway (Events API), to collect signalling, RTCP reports, app-specific events and have them correlated and presented in a user-friendly GUI.
For advanced users, we'll present the installation of captagent, the standalone capture agent, hepgen.js to generate test traffic, and a Wireshark dissector to have full visibility of data flows.
Considerable improvements can be achieved by automating the integration of Kamailio-based projects: automated builds, tests and deployments save time and increase reliability. This presentation focuses on common practices to automate the build of Kamailio (and RTPEngine) on various distributions and deploy them, together with their configuration, on testing and production environments.
Docker plays an important role in providing flexible, clean building environments and keep the process reproducible. We’ll see how Jenkins can orchestrate the builds with Docker slaves, and perform the deployments with a combination of platform-specific packages, Fabric, Puppet and Ansible.
netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.
iptables is a user-space application program that allows a system administrator to configure the tables provided by the Linux kernel firewall (implemented as different netfilter modules) and the chains and rules it stores.
Many systems use iptables/netfilter, Linux's native packet filtering/mangling framework since Linux 2.4, be it home routers or sophisticated cloud network stacks.
In this session, we will talk about the netfilter framework and its facilities, explain how basic filtering and mangling use-cases are implemented using iptables, and introduce some less common but powerful extensions of iptables.

The Art of the Pitch: WordPress Relationships and SalesLaura Byrne
Clients don’t know what they don’t know. What web solutions are right for them? How does WordPress come into the picture? How do you make sure you understand scope and timeline? What do you do if sometime changes?
All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
