Hey everyone 👋 I'm building an insurance receptionist assistant on VAPI with a Twilio number. I need help combining two features: My situation: Agent phone number is fetched dynamically from Salesforce via HTTP tool Different agent number for every caller — can't hardcode it What I need: Dynamic transfer number ✅ (working via transfer-destination-request webhook) Fallback plan if agent doesn't answer ❌ (breaks the transfer when added) What I've tried: Adding transferPlan + fallbackPlan to the webhook response → transfer fails immediately PATCH with hardcoded number + fallbackPlan → fallback works but loses dynamic number server as destination type → 400 Bad Request Placeholder in destination number field → rejected due to E.164 validation My question: Is there any way to have both a dynamic agent number AND a fallback plan work together in VAPI? Or is this a known limitation? Any help or workaround appreciated! 🙏
