Building a Softphone for scale

Modern softphones have gone beyond user interfaces and SIP endpoints, becoming distributed, fault-tolerant communication systems designed for global scale. As organizations adopt hybrid Asterisk environments, there's a need for scalable softphone architectures connecting WebRTC, SIP, mobile, and AI platforms.

This session will use SIPERB as a case study to explore the challenges and patterns of building a large-scale softphone platform. We’ll examine the backend ecosystem, including SIP proxies and media relays, and explain why scalability and interoperability are crucial from the start.
You'll learn to build a reliable softphone for browsers and mobile devices, using modern WebRTC architectures to keep your Asterisk core lightweight and secure. We'll also demonstrate how a standards-based, event-driven architecture allows integration with platforms like WhatsApp and OpenAI for AI analysis and cross-platform communication.
