Build a Santa Voice Agent 🎅 | Magical Christmas Surprise AI

Ever wished Santa would actually call you? In this tutorial, you’ll build a festive voice agent that dials real phone numbers and speaks in a Santa voice, using Retail AI, N8n, Twilio, and Eleven Labs. We go end-to-end: crafting conversational prompts, cloning Santa’s voice, wiring SIP trunking, and triggering inbound/outbound calls—all in minutes. The result is a production-ready agent with low latency, dynamic variables for personalization, and proper geo and auth settings so it works reliably across countries.

By the end, you can publish your agent, attach a webhook for programmatic calls, and even surprise friends with a personalized Santa greeting.

What you’ll learn:

Prompt design: role, task, flow, examples; making the AI speak first; adding dynamic variables like first_name.

11 Labs voice setup: finding a Santa voice ID and adding a custom voice.

Retail AI configuration: model selection, multilingual options, voicemail behavior, publishing versions.

Twilio setup: buying numbers, SIP trunking, termination/origination URIs, credential lists, geo-permissions.

Webhooks and curl: bearer auth with API keys, posting JSON payloads to trigger calls.

TIMESTAMPS:
00:00 — Santa call demo and intro. ​⁠
03:20 — Create agent in Retail AI: single‑prompt flow and examples. ​⁠
06:54 — Add Santa voice via ElevenLabs voice ID. ​⁠
08:00 — Configure model, language, and latency trade‑offs. ​⁠
08:55 — Real‑time vs custom voice; pick model (Gemini 2.5 Flash). ​⁠
12:02 — Twilio setup: buy number; Elastic SIP Trunking. ​⁠
14:06 — SIP Termination: URIs and credential list. ​⁠
15:56 — SIP Origination: inbound calls wired. ​⁠
20:12 — Inbound call working test. ​⁠
20:46 — Outbound call setup and dynamic variables. ​⁠
21:16 — Outbound call demo. ​⁠
21:41 — Common errors: payment, geo‑permissions, auth mismatch. ​⁠
22:21 — Geo‑permissions configuration across countries. ​⁠
24:00 — Webhook flow in n8n; bearer auth and API key. ​⁠
25:28 — HTTP POST body and passing dynamic variables (first_name). ​⁠
26:40 — Trigger with curl; live call fires. ​⁠
27:20 — Closing and next‑steps teaser. ​⁠
