So i posted some help about an hour ago asking if i can transfer calls with my vapi assistant and twilio. Number. Im a bit stuck with the api routing. I have this api call and when i try to send the call to my api or somewhere to transfer the function im having trouble getting it to work. I had it so when a person asks to speak to the front desk it calls my applicaiton and then it respons with twilio xml saying to dial the number but this did not work. Im a bit stuck at the moment and help help would be huge. curl --request POST \ --url https://api.vapi.ai/call/phone \ --header 'Content-Type: application/json' \ --data '{ "assistant": { "model": { "tools": [ { "type": "transferCall", "function": { "name": "Send-ToFrontDesk", "description": "Send the user to front desk." } } ], "model": "gpt-4o", "provider": "openai" }, "transcriber": { "provider": "deepgram" }, "firstMessage": "Hey", "metadata": { "message1": "Here is my text message" }, "serverUrl": "https://api.clientbase.so", "serverMessages": [ "end-of-call-report" ] }, "customer": { }, "phoneNumber": { }, "assistantOverrides": { "model": { "provider": "openai", "model": "gpt-4o" } }, "metadata": {} }'

1. yes my twilio api handle goes to vapi so when someone calls it starts with vapi. 2. nope i tried to respond to it with xml, this is my server route // New /dial endpoint to handle call transfer app.post('/dial', (req, res) => { console.log('Incoming /dial request'); console.log('Headers:', req.headers); console.log('Body:', req.body); const twiml = new twilio.twiml.VoiceResponse(); twiml.dial('+15865660231'); // Transfer the call to the specified number const twimlString = twiml.toString(); console.log('TwiML Response:', twimlString); res.type('text/xml'); res.send(twimlString); }); and this is the console log TwiML Response: +15865660231 https://cdn.discordapp.com/attachments/1248762647814606949/1248763598948536380/image.png?ex=6664d93a&is=666387ba&hm=d38be92b39d823e91e67aebd4dfbe079a8a993fbb023adce89cbc93c09fabd1a&
