Presentation done at Astricon 2013, Atlanta, USA - a look at Kamailio and SIP proxy server concept from the perspective of a media server and PBX such as Asterisk
Kamailio combined with Asterisk creates and incredibly robust and durable VoIP framework. With scalability and security, adding Kamailio to an asterisk deployment makes sense and saves money.
Kamailio is the leading Open Source SIP Server - a SIP proxy, registrar, location server, presence server, IMS server and much more. Find out more by viewing this quick presentation! (Updated June 2014)
Asterisk is an Open Source PBX - but how does it support larger installations? Can you scale it up to thousands of users, with hundreds of simultaneous calls? What about failover, backups and the famous blinking lamps? Olle Johansson goes through various models and describes where some of his current projects with strange names - Pinefrog, Pinana, Pinetree and Bufo fits into this picture.

Using Asterisk and Kamailio for Reliable, Scalable and Secure Communication S...Fred Posner
Presentation from AsteriskWorld 2017 at ITEXPO. Discussion of how I started with Asterisk and Kamailio as well as how to build Reliability, Scalability, and Security into your telephony platform.
Introduction to Kamailio (TADSummit 2020 Asia)Fred Posner
Quick introduction to Kamailio, the open source SIP server (https://www.kamailio.org).
Kamailio® (successor of former OpenSER and SER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second. Kamailio can be used to build large platforms for VoIP and realtime communications – presence, WebRTC, Instant messaging and other applications. Moreover, it can be easily used for scaling up SIP-to-PSTN gateways, PBX systems or media servers like Asterisk™, FreeSWITCH™ or SEMS.
SIP servers on embedded systems: Powering SoHo communicationsRADVISION Ltd.
Increasing number of small offices/home offices (SoHo) migrate to VoIP communication based on commodity appliances that provide the connectivity solution.
The appliance is in many cases a combination of:
* Residential gateway (RGW)
* Integrated access device (IAD)
* Key-system/ small PBX
* SIP firewall / GW
In some cases it even can be as part of a set-top box.
All the above is based on SIP server technology that is tailored to embedded devices. This technology involves significant business potential as well as technology challenges that will be elaborated on the webinar.

Presented at RailsConf 2007, this presentation introduces the Telegraph plugin for briding Asterisk and Rails.
Telegraph brings the beauty of Rails programming to the VoIP world. It reshapes the mess of the Asterisk API into MVC cleanliness allowing the rapid development of Rails based voice and web applications.
SUMMARY :
We all have the contradictory feeling to deliver not-so-bad projects, with no-so-bad performances.
But what really is an perfectly optimized project ?
For you : optimized PHP code & SQL queries
For your boss : the customer who never complains
For the customer : own experience on his workstation
For the business : who really know and care ?
For end-user : who can really know the end-user experience (could be millions of users) ?
Without losing interest on technical aspects (PHP, MySql, Solr, Varnish, CDN, etc.) & softwares (new relic, jmeter, etc.), this presentation will send a feedback from real projects to :
How to integrate performances within the project scope ?
What & how to measure & collect smart metrics ?
Enlarge the scope : from your dev workstation to the end-user… in china !

Open Source Telecom Software Landscape by Alan QuayleAlan Quayle
There are tens of successful Open Source Telecom Software projects, with vibrant communities supporting them. Asterisk, the most successful and longest running is 20 years old. We heard from them earlier in the agenda.
We’ll review the many other projects to help people understand the depth, breadth and rapidly evolving nature of these projects. As we’ll as some of the new projects like Drachtio.org, and used recently at TADHack-mini Orlando Online 2020, for the hack SMB Reschedule.
We’ll also review the results from an anonymous survey of open source telecom software. Comparing the different projects, the preferred application areas of the projects, common issues and solutions, sharing where the industry sees these projects in 5 years’ time.
Kamailio 5.0 allows writing full routing logic in Lua scripting language, opening the door for easy integration with external services and increasing the flexibility of optimizing SIP routing.
Dangerous demo at TAD Summit 2016, in Lisbon. Running Kamailio on Ubuntu Phone, turning it into a SIP routing platform for large number of requests per second. The demo was done by stressing with sipp at a rate of 2000req/sec while audience was able to make calls between them.
Fosdem 2016, Brussels, Belgium
A developer perspective of the components in the C code that impact the performances of the signaling servers, applied for Kamailio (https://www.kamailio.org), reflecting how they can be tuned from configuration file to increase the capacity of a SIP server.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
