Do Androids Dream of Making VoIP Calls

In a quantum AI world, how will we (or our AIs) communicate? Which Science fiction communication devices are becoming a reality.

James Tagg is a serial entrepreneur, physicist, and award-winning author. He was one of the original inventors of the touchscreen now found on all mobile phones. He founded Truphone, the world’s first global mobile network, making the first VoIP call on a mobile phone and developing the eSIM. During COVID-19, he built a quantum computer in his garage, which explores ‘the measurement problem’ allowing faster quantum computers to be built. He is currently the Chief Architect for World Mobile a Web3 mobile carrier launching in the USA. His first book, Are the Androids Dreaming Yet? Explores the limits of Artificial Intelligence and the differences between humans and computers.

Kamailio as a SIP Application Server

Kamailio is well known for its scalability and flexibility for SIP routing, but is that all? What else it can do? This presentation shows some of the SIP application server features that can be run with Kamailio, such as instant messaging conferencing, MSRP, XCAP and presence services, gatewaying to social media, basic media server, DIAMETER router or SMS center.

Daniel co-founded Kamailio in June 2005, aiming to build a solid SIP server project where openness to community and contributions has an important role, previously being core developer of SIP Express Router (SER) from its early beginning in 2002. He has a Master’s degree in Computer Science and Engineering from the Polytechnics University of Bucharest and worked as a researcher in network communications at Fraunhofer Fokus Institute, Berlin, Germany. His activity is done at Asipto, a company targeting to offer and build reliable services and solutions that benefit at maximum from Kamailio’s flexibility and features.

Dynamic SIP Credentials

Learn how to use Kamailio to generate dynamic SIP credentials that expire after a certain amount of time. Engineers sometimes forget to remove SIP credentials of test carriers from a customers system after performing testing, and wouldn’t catch it until a fraud notification from the carrier or receive the monthly bill. Therefore, we created a RESTFUL endpoint called “/lease” and it creates a set of SIP credentials that are only active for a defined timeframe. Once, the timeframe is reached the credentials are automatically removed from Kamailio.  Using SIP dynamic credentials versus using long-lived credentials is more secure when building new environments and performing automated testing using CI/CD. Credentials are automatically removed once testing is complete.

He works with them to develop their idea and a Minimal Viable Product (MVP) with the desire to find a product-market fit.

Build 5G Stand Alone Private Network with Open Source

Mobile network technologies, for a long time, were known to be anything but affordable, especially for small companies and individuals. However, over the past few years, supported by software defined networks, the costs for radio access hardware went down. Allocation of testing spectrum licenses has been made more flexible and open source started also to play a relevant role, considerably lowering the entry barrier for research and development in the mobile networks space. This session presents how one can build an affordable 5G SA private network using open source only software, which then can be used for testing, prototyping and beyond.

Elena-Ramona Modroiu is a researcher at AV Chair of Technischen Universität (Technical University) Berlin, Germany, leading the research group for open source mobile technologies, focusing on leveraging open source to facilitate student’s access to complex RTC systems and to define next generation communication services. She has a master degree in Computer Science Engineering from Polytechnics University of Bucharest, Romania. She has been directly involved in a couple open source projects for more then two decades, among them: Kamailio SIP Server and Siremis.

From Texting to TikTok: Defining Digital Regulation

We’ve all heard the recent TikTok drama, the push to ban its use in the US. We’re not going to comment either way, but it does bring up the very controversial topic of digital regulation. TikTok is being questioned due to software and database ownership, should it raise concerns about national security?

Business texting is experiencing the drama of regulations, as well. The US mobile carriers decided to set up their own regulation authority, and it worked, they got a good portion of business to sign up with their registry or else they wouldn’t deliver 10DLC, or A2P business text messages. We all handed over our data, and content of our messages that would be sent from each specific phone number. It passed through a company-run registry that the US carriers deemed their official reputation authority, and if approved, it is then vetted again by the carriers, all before messages can be sent. Is this ok?

Tom Sheahan is CEO/Co-founder of Red Oxygen. As one of the visionaries of the A2P messaging space, Tom and Red Oxygen delivered the world’s first SMS through Outlook ’97 using Nokia 5110s before the CPaaS space existed. Tom has over 30 years of experience in the U.S. and Australian IT/Telecommunications industry.

Hepic Cloud: The Challenges of Building an RTC Architecture in Cloud & How it’s Going

Nowadays micro-services are seen as the only way to do an architecture, and in particular, Kubernetes is used to do everything. However, most of the time the complexity that comes along with such an architecture is not taken into consideration, compared to the service/product we are trying to deliver, especially in the RTC world having a super-dynamic architecture is a challenge on its own. Hepic Cloud – some mistakes were made when designing its architecture, to the point where we are now in Hepic Cloud version 2. After all the struggles to get here, we want to share lessons learned and how Hepic Cloud drastically simplifies your observability stack and allows you to focus on what’s important while we maintain everything else. And yes, AI is part of the equation.

Modernizing a Legacy VoIP Stack

Your VoIP stack is the engine of your business. It connects the calls. It makes the money. But, what do you do when it’s stale, old, and no one knows how it works?

Brandon started out working in technical support, but saw that there was a big gap of VoIP knowledge and development skills. Especially when it came to Asterisk and Freeswitch.
