I’m working on getting Twilio app-to-phone voice calls working.

Here’s my current flow.

• Client clicks the “Make Call” button on my website.
• My site sets up the Twilio device and calls const call = await twilioDevice.connect({ params });
• On my server, the endpoint specified in Twilio App-> Voice Configuration ->Request URL is hit. This endpoint is called “/make-calls” (This all seems to work as expected up to this point).
• My “make-calls” endpoint calls twilioClient.calls.create() and returns this xml to Twilio:

    <Response>
        <Connect/>
    </Response>

• There are no errors shown by Twilio, but in console.log on the client I see:

console.js:288 [TwilioVoice][Call] Received an error from the gateway:
ConnectionError: ConnectionError (31005): Error sent from gateway in
HANGUP
at Call._onHangup (call.js:291:23)
at PStream.emit (events.js:161:5)
at PStream._handleTransportMessage (pstream.js:148:10)
at WSTransport.emit (events.js:161:5)
at WSTransport._onSocketMessage (wstransport.js:156:18)

The client immediately hangs up the call. The callee’s phone rings, but no one is on the other end to talk to.

My server console.logs show that ‘/twiml’ endpoint is never hit, and neither is my ‘handle-amd-result’ endpoint.

What am I leaving out?

Here's the code from my "make-calls" endpoint:

console.log('-----')
console.log('/make-call. req?.body:', req?.body);

let nurseId = req?.body?.nurseId;
const navData = await getNavigatorData(nurseId);
const toNumber = navData?.phone_1;
let nurseName = navData?.name_first;
const twilioPhoneNumber = Meteor.settings.private.twilio.phoneNumber;
console.log('toNumber:', toNumber);


let xml = '';
const twilioClient = twilio(accountSid, authToken);
try {
    const call = await twilioClient.calls.create({
        url: `${baseUrl}twiml`,
        to: toNumber,
        from: twilioPhoneNumber,
        // twiml: twimlString,
        machineDetection: 'Enable',
        AsyncAmdStatusCallback: `${baseUrl}handle-amd-result`,
        statusCallbackEvent: ['initiated', 'ringing', 'answered', 'completed'],
        statusCallbackMethod: 'POST',
        machineDetectionTimeout: 30
    })

    let responseObject = {
        Response: {
            Connect: true,
            Play: true
        }
    }
    xml = xmlJs.js2xml(responseObject, xmlJsOptions);
    xml = "<Response>n" +
        "    <Connect/>n" +
        "</Response>"
    console.log('xml: ', xml)
    res.set('Content-Type', 'text/xml');
    res.status(200).send(xml);
} catch (err) {
    let responseObject = {
        Response: {
            Success: false,
            Message: 'Failed to initiate call',
            Error: err.message
        }
    }
    xml = "<?xml version="1.0" encoding="UTF-8"?>" + xmlJs.js2xml(responseObject, xmlJsOptions);
    res.set('Content-Type', 'text/xml');
    res.status(500).send(xml);
}
