The telephony stack for the AI age

What if your next phone call with a customer-support bot felt as seamless as chatting with a human? In this session, we’ll explore how telephony needs to be reinvented for real-time AI—shifting from the classic “phone call + cloud server” model to an edge-optimized, AI-first infrastructure. We’ll dive into the technical blueprint of a new telephony stack that collocates speech recognition, large language models, and text-to-speech engines in global edge data centers—slashing round-trip latency and driving more natural, human-like conversations.

Expect a guided tour of key AI voice enhancements, from neural audio super-resolution (that can upscale low-fidelity PSTN calls on the fly) to advanced noise reduction techniques that enable accurate transcriptions even on spotty mobile networks. We’ll also address scalability: how to architect a serverless call-control layer that autoscales instantly for spiky workloads. Whether you’re working in conversational AI, contact centers, or next-gen virtual assistants, join us to see how the telephony stack of the AI age can deliver truly real-time, high-fidelity voice interactions—and why it might just change how we communicate forever.
