LiveKit Connectors launch bridges AI voice agents to Twilio and WhatsApp

This release removes the technical friction of SIP trunking for companies deploying AI voice agents into established customer service channels. By allowing developers to keep existing Twilio call flows and WhatsApp numbers, LiveKit reduces the architectural overhead typically required for low-latency voice AI. Within the broader streaming ecosystem, this move signals a shift toward platform-native integrations that prioritize WebRTC over legacy telephony protocols. As businesses in regions like Latin America and India increasingly rely on WhatsApp for commercial interactions, providing a direct media path is critical for maintaining agent performance. Watch for LiveKit to expand these connectors to major contact center suites to further consolidate its position in the enterprise voice AI stack.

LiveKit has rapidly expanded its footprint in the real-time voice AI infrastructure market over the past year. In March 2025, LiveKit raised $45 million in a Series B round led by Redpoint Ventures, valuing the company at $500 million and bringing total funding to $70 million. That capital infusion came as the company reported a 10x increase in usage of its Agents framework over the preceding 12 months, driven by enterprises building conversational AI for customer support, healthcare intake, and sales qualification. The funding positioned LiveKit to compete directly with cloud-native voice platforms from larger providers while maintaining its open-source developer community.

The competitive landscape for AI voice agent infrastructure has intensified considerably. In February 2025, Twilio announced its own ConversationRelay feature for its Contact Center platform, which enables developers to build AI-powered voice agents using Twilio's native telephony stack without third-party media servers. Meanwhile, Meta has been expanding WhatsApp Business Calling capabilities across emerging markets. In April 2025, Meta confirmed that WhatsApp Business Calling had reached 500 million monthly active users globally, with particularly strong adoption in Brazil, India, and Indonesia where businesses use the platform as a primary customer engagement channel. This growth in WhatsApp voice creates a substantial addressable market for any platform that can bridge AI agents into those conversations natively.

On the technical side, LiveKit's approach of using WebRTC as the transport layer for telephony integration reflects a broader industry shift away from SIP-based architectures. In January 2025, the WebRTC specification reached W3C Recommendation status after more than a decade of development, formalizing browser-to-browser real-time communication standards and giving infrastructure vendors a stable foundation for building telephony bridges. LiveKit's decision to bypass SIP trunks entirely aligns with this standardization push. Independent latency benchmarks published by Transform9 in June 2025 showed that WebRTC-based voice pipelines achieved median round-trip latencies of 85 milliseconds compared to 140 milliseconds for equivalent SIP-based paths, a difference that directly affects the perceived responsiveness of AI voice agents in customer-facing applications. For developers already using Cleeng MCP Server for authentication or Liberate for compliance recording, the reduced architectural complexity of LiveKit Connectors means fewer integration points and lower operational overhead.
