Synopsis

Node.js/Express template bridging Twilio Voice Media Streams to Deepgram's Voice Agent WebSocket API to build an AI phone agent. Demo use case is a pizza-shop order-status agent with function calling, barge-in support, and both inbound (TwiML webhook) and outbound (Twilio REST) call handling, using μ-law 8 kHz audio end-to-end.

Reasoning

Clears all disqualifiers: it's a real multi-component voice AI template with a clonable repo, not a single-vendor hello world (composes Twilio + Deepgram Voice Agent + OpenAI LLM) and not a marketing page. Schema-able and forkable are maxed out — repo, README, .env.example, exact model strings. Stack covers all five layers with named products. Outcome is concrete (pizza shop order status lookup) but the industry framing is demo-ish rather than a tightly-named vertical, so C3 lands at 3. Weighted total 4.6 → fit 5.
