IVR JS Example (EMAIL)

This example demonstrates a IVR script using Vodia's Javascript IVR capabilities, incorporating TTS, DTMF collection, communication with an external application and automatically sends emails to customers based on their inputs.

Scenario:

Play a welcome message using Vodia's TTS.
Collect a 4-digit input from the user via DTMF.
Send the collected digits to an external application in JSON format.
If the JSON response includes an email address, send the details to that address and transfer to an Auto attendant '10'
If no email address is found, play the provided message and transfer the call to the destination specified in the JSON response.

'use strict';

call.say('Welcome to company ABC. Please enter your 4 digit customer number and we will email your details to the nominated email address.');

var digits = '';

call.dtmf(ondtmf);

function ondtmf(digit) {
  digits += digit;
  if (digits.length == 4) {
    send(digits);
    digits = '';
  }
}

function send(digits) {
  var body = JSON.stringify({
    customerCode: digits
  });

  var args = {
    method: 'POST',
    url: 'https://extenal_server/webhook',
    header: [ { name: 'Content-Type', value: 'application/json' } ],
    callback: callback
  };

  if (body) {
    args.body = body;
  }

  system.http(args);

  function callback(code, response, headers) {
    console.log('IVR response:' + response.toString());
    console.log('IVR response:' + code.toString());
    
    
      var res = JSON.parse(response);

      
      // If there's an email address in the response, send details
      if (res.email) {
        var emailArgs = {
          to: system.parseEmailAdr(res.email),
          from: { name: "Company ABC Support", adr: "support@companyabc.com" },
          subject: "Your Details requested",
          body: res.message
        };
        
        system.email(emailArgs);
        call.say("We have emailed your details requested.");
      }
      
      // If there's a transfer request, process it after a delay
      if (res.transfer) {
        call.say(res.message);
        setTimeout(function() {
          call.transfer(res.destination);
        }, 10000);
      }
      if (res.transfer == null) {
        setTimeout(function() {
          call.transfer('10');
        }, 5000);
      }

  }
}

The external application, in response to the JSON data sent by the Vodia PBX, should return a JSON object with specific fields.

{ "destination": "785","message": "Thanks Mr. Jones we could not find your email transfering you now", "transfer": "true" }

{ "email": "pbx@vodia.com","message": "Thanks Mr. Jones , your access code is 1234" }

tip

Use 'Connection': 'keep-alive' header in your response.
