Is there a way to reject a call before Twilio and VAPI answers it

app.post("/webhooks/vapi", (req, res) => {
  const spamNumbers = new Set(["+11234567890"]);
  const incomingNumber = req.body?.call?.from?.phoneNumber;
  if (incomingNumber && spamNumbers.has(incomingNumber)) {
    return res.json({ error: "Sorry, your number is blocked due to spam reports." });
  }
  // ...proceed with call
});
