CallStorm is a short, dramatic demo of what an AI call center could look like if you built it from scratch on Cloudflare and gave it a voice with ElevenLabs. The idea is simple: Karen is furious because her overnight package never showed up. Marcus, an AI support agent, picks up the call, calms her down, checks the live tracking data, looks at policy, and fixes the issue on the spot with a replacement and a credit. The point of the demo is that it is not just a fake scripted animation. The call is orchestrated on Cloudflare, the tool calls are real, and the tracking response comes back as structured JSON in the UI while the conversation is happening. Under the hood, we used Cloudflare Workers, Durable Objects, the Agents SDK, Workers AI, D1, KV, and Queues to run the call flow and the tools. ElevenLabs handles the voices for Karen and Marcus. What makes the demo fun is that Marcus briefly breaks the fourth wall to explain the stack to the judges, then jumps straight back into handling Karen’s complaint.
