Behind the seemingly seamless experience of WebRTC is a sophisticated network of servers and protocols that manage real-time, peer-to-peer connections across browsers, native applications, and media servers. Setting up and maintaining these connections requires various steps, each essential for reliable and efficient communication. In this post, we’ll dive into two key components of this infrastructure: STUN (Session Traversal Utilities for NAT) and TURN (Traversal Using Relays around NAT) servers. We’ll explore their functions, how they

As part of a larger project, our team at WebRTC.ventures had the opportunity to develop a native Android SDK to expand SignalWire’s WebRTC capabilities beyond its existing React Native solution. This SDK provides a platform-specific implementation tailored to Android, allowing us to address mobile-specific challenges, such as handling variable network conditions and optimizing real-time performance.  In this post, we’ll share how we approached the project, from selecting Kotlin as the development language to overcoming technical

For developers building real-time voice applications like our team does at WebRTC.ventures, 2024 has been an exciting year. OpenAI's Realtime Audio API and open-source alternatives offer new and distinct approaches to integrating live voice capabilities. As WebRTC and real-time AI converge, the right choice depends on your application’s needs for latency, scalability, and control.  In this post, we'll compare OpenAI's multimodal API with open-source solutions, examining their architectures, integration complexity, customization options, and latency performance

This week, our partner Vonage hosted its Q4 2024 Video API Roadmap and Q&A session, announcing recent and upcoming updates to enhance security, performance, and user experience on their Video API platform and SDKs. These changes benefit businesses aiming to improve their video communication capabilities. In this post, we'll highlight key updates and their impact on companies building with Vonage or improving their existing WebRTC applications.

When I attended the CommCon London conference earlier this year, one of the speakers, Michał Śledź, invited us to join the RTC.ON conference. It was organized by his company, Software Mansion, and was going to happen in Krakow on September 11-13, 2024.  A few days after returning home, I sent a proposal to be a speaker at the conference. It was accepted!  A couple months later, I arrived in Krakow!  Here is my summary of

Session Initiation Protocol (SIP) and WebRTC are both essential technologies in the field of real-time communications, particularly for voice and video over IP. While they serve complementary roles, they operate differently and have distinct functionalities. In this post, we explore how to architect the integration of WebRTC and SIP using Multipoint Control Unit (MCU) and Selective Forwarding Unit (SFU), enabling businesses to modernize their communication infrastructure without abandoning existing systems. Understanding the Relationship Between SIP

On the October 16, 2024 episode of WebRTC Live, host Arin Sime welcomed Rob Pickering, CEO of Aplisay, to explore the fast-changing landscape of conversational AI and streaming speech.   Bonus Content Our regular monthly industry chat with Tsahi Levent-Levi. Watch Episode 95! https://youtube.com/live/0G_6rwJVTJU Key Insights ⚡ We’re slowly moving to more fluid, natural conversations with AI.

OpenAI's new Realtime API represents a significant advancement in AI-powered communication, enabling speech-to-speech conversations with near-instantaneous processing time. The API delivers natural voice interactions through six distinct voice presets, integrating seamlessly with real-time applications. A few months ago, we showed you how to build an AI-powered WebRTC application from scratch called Polybot.ai. Polly, as we like to call her, is a real-time language translation application using Large Language Models (LLMs). It allows business professionals, travelers,

As we continue to navigate the complexities of remote work and virtual interactions, the demand for seamless and engaging video conferencing experiences has never been greater. WebRTC has long been a key player in enabling real-time communication between participants, but recent advancements in Artificial Intelligence (AI) are taking these capabilities to new heights.  In this post, we'll explore the exciting ways AI is transforming WebRTC video conferencing applications—from media processing and transport to productivity-boosting features

The global shift to e-learning and online education during the pandemic fundamentally reshaped digital learning platforms and propelled the development of more sophisticated edtech solutions. Central to this transformation is WebRTC technology. Beyond browser-based video conferencing, WebRTC enables crucial educational features like real-time collaborative whiteboards through data channels, screen sharing for interactive demonstrations, adaptive video quality for varying network conditions, easy device switching for different learning environments, and native recording capabilities for session review. The

At WebRTC.ventures, testing is a crucial part of our development process. Whether it’s manual testing or automated testing, BrowserStack has become our go-to tool. In this post, I’ll share our experience on how BrowserStack makes testing more accessible, faster, and more efficient for our QA teams. What is BrowserStack? For those who may not be familiar with it, BrowserStack is a cloud-based testing platform that allows developers and QA teams to test applications across a

Systematically transcribing, summarizing, and analyzing contact center calls reveals critical data. This information can be used to improve efficiency, enhance the customer journey, uncover business trends, ensure compliance, and much more. With AI and ML, there's no reason for contact centers to operate 'in the dark.' To address this need, we've combined three powerful AWS services and built a data-driven dashboard that can be tailored to deliver actionable insights specific to your industry and operations.

What if your mobile app had direct access to data about the telecommunications network it’s running on? What would you do with additional data about things like the quality of your connection, and the device that your application is running on?  I’ve been hearing about the potential power of Network APIs for a while. Since our team at WebRTC.ventures builds web and mobile applications using live video and voice, this is very relevant to our

Media over QUIC is gaining momentum, AI in video is definitely here but not quite ready for real-time, and the WebRTC community continues to be vibrant. Those are just a few of my takeaways from the excellent RTC.ON conference that I attended in Krakow, Poland last week.  In the video below, I share some sights and sounds from the conference. Keep scrolling after that, as this post will go into more detail about the conference
