Show and tell: dual-channel AI (Vapi phone + OpenAI web) on one CSV log

Twin-channel AI without two truths\n\nPhone (Vapi) and web chat (OpenAI) on the same brand should not drift.\n\nPattern I shipped:\n\n1. One master persona / knowledge attachment (versioned filenames)\n2. Two ingress webhooks → same append-only log\n3. Owner reply link after escalation\n4. Verified FAQ memory for prices, books, mission facts\n\nLive on elionmusic.com. Happy to walk through architecture with anyone building receptionist-style agents.\n\n*Want a dev friend who gets webhooks + email + cPanel?* Comment with your stack.
