I do not see any documentation in creating a conference call in twilio functions
You could start with something like this:
exports.handler = function(context, event, callback) {
// create response object (to return TwiML)
let response = new Twilio.twiml.VoiceResponse();
// dial a conference room
const dial = response.dial();
dial.conference('Some Room');
// for debug
console.log(response.toString());
// return conference TwiML
return callback(null, response);
};
This is similar with how a forward call Twilio function would be, but instead you "dial" a conference room, not a number.
Configure your Twilio number so it runs the function when a call comes in.
With the new Twilio functions interface, you'll need to create a service before you create a function. If you want to see the logs, you'll need to togle "Enable live logs" to see the console.log(response.toString());
.
You can get more inspiration from the docs for Node.js here: https://www.twilio.com/docs/voice/twiml/conference
