Challenges of scaling and testing at scale WebRTC applications

As WebRTC continues to dramatically lower the barriers for building RTC services, many scenarios require an infrastructure able to scale to meet customer demands. Correctly estimating the capacity, optimizing quality and minimizing costs play a fundamental role in the success of many service providers. In this presentation I talk about the main challenges for scaling and testing at scale, with an example based on SignalWire client SDK.

Fleet Edge Voice has Freeswitch at its heart, allowing voice services with centrally provisioned numbering and high reliability with automatic fallback from GX to BGAN; a unique offering. Martyn will describe how Inmarsat uses Freeswitch features to provide on-ship calling and remote management from the shore.

Richard Fuchs – Sipwise

For the past 15 years Richard has been responsible for all things RTP at Sipwise, where he continues to be the main developer of RTPengine. He is entirely self-taught and uses his previous experience working in an ISP environment to combine his knowledge of network technologies with his knack for low-level software development to create high-performance and scalable open-source software, largely focused on real-time communication.

Fast kernel-level SFU with RTPengine

While RTPengine has traditionally been used mainly as a media proxy for one-to-one SIP calls, its latest versions include features that enable it to fork media to multiple destinations, allowing it to be used as SFU, conferencing service, SIPREC SRC, LI gateway, and more. These new features can be used in conjunction with its already existing feature set, which most notably include a custom Linux kernel module to facilitate high-performance and low-latency packet forwarding, as well as WebRTC bridging and audio transcoding.

How would you like your calls? On the rocks or STIR & SHAKEN?

It has become imperative to verify incoming calls to decipher the caller’s identity and verify that they are legitimate. In case the incoming calls are not verified for their credibility, scammers can camouflage their presence and prove a threat to the end-user. STIR/SHAKEN is a technology framework that assures that the identity of the user making call is trustworthy, earning the badge of reliability. In this session, learn more about how to incorporate STIR/SHAKEN in your strategy to emerge as a business winner and know how you can lower the risk of fraudsters.
