twilio-incident-response.md

A Twiml with the following content:

<?xml version="1.0" encoding="UTF-8"?>
      <Response>
        <Dial>
          <Number
            statusCallbackEvent="answered"
            statusCallback="https://crimson-hawk-9615.twil.io/update-status"
            statusCallbackMethod="POST"
          >
            (786) 528-8304
            (785) 528-8303
            (784) 528-8302
          </Number>
        </Dial>
      </Response>

And two functions:

One for the redirect SMS:

exports.handler = function(context, event, callback) {
    const twiml = new Twilio.twiml.MessagingResponse();

    twiml.message("At this time, MLH is only able to receive calls on this number. Please try calling the number or emailing incidents@mlh.io");
    callback(null, twiml);
};

And another for updating the other numbers that are also on call for one specific incident response number:

exports.handler = function(context, event, callback) {
  const attendant = event.To;
  const twilioNumber = event.ForwardedFrom
  const caller = event.Caller

  const phoneNumbers = [
    '+17865288304',
    '+17565288303',
    '+17465288302',
  ]

  const filteredNumbers = phoneNumbers.filter((phoneNumber) => {
    return !attendant.endsWith(phoneNumber)
  });

  const twilioClient = context.getTwilioClient();

  filteredNumbers.forEach((phoneNumber) => {
    twilioClient.messages.create({
      from: twilioNumber,
      to: phoneNumber,
      body: `Call from ${caller} answered by ${attendant}`,
    }, function(err, result) {
      callback();
    });
  })
};
