Cloud service for outbound call messaging

Question

I would like to integrate a service as. Apart of our product signin that will call the user to give them a code.

I can generate codes as mp3 without issue but I don't know of a service that can place the call and then play the mp3 to the user.

Any thoughts or feedback on this sort of app need?

Highly recommend Twilio Cloud Communication, it can be used to send the code via SMS or by a phone call.

Using PHP as an example, here is how it would look -

Text Message

<?php
// Get the Twilio PHP Library from http://twilio.com/docs/libraries
require "Services/Twilio.php";

//Random Code
$code = rand(pow(10, 6-1), pow(10, 6)-1);

// Set your Twilio Account settings
$AccountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
$AuthToken = "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY";

//Initial Twilio instance
$client = new Services_Twilio($AccountSid, $AuthToken);

//Recipient number - must be +15555555555 format
$recipient = '+18882224444';
$caller_id = '+18008885555'; //Twilio phone number

//Send the message
$sms = $client->account->sms_messages->create(
    $caller_id,
    $recipient,
    "Your activation code is: $code"
);

Phone Call

<?php
// Get the Twilio PHP Library from http://twilio.com/docs/libraries
require "Services/Twilio.php";

// Set your Twilio Account settings
$AccountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
$AuthToken = "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY";

//Initial Twilio instance
$client = new Services_Twilio($AccountSid, $AuthToken);
$call = $client->account->calls->create(
    '9991231234', // From a valid Twilio number
    '8881231234', // Call this number

    //When the call is connected, code at this URL will be executed
    '/say-code.php'
);

say-code.php

<?php
// Get the Twilio PHP Library from http://twilio.com/docs/libraries
require "Services/Twilio.php";
// Random Code
$code = rand(pow(10, 6-1), pow(10, 6)-1);

// Generate TwiML - XML for Twilio
// This will execute when the caller is connected and use Text-To-Speech to
// play their activation code.
// You may also use an MP3 like so:
// $response->play('http://example.com/code.mp3');
$response = new Services_Twilio_Twiml();
$response->say("Your activation code is $code");
print $response;

There are a lot of other helper libraries out there to accomplish this with Twilio. Hope this helps!
