How do you place a phone call using tropo by sending xml to a tropo hosted script? This php script is supposed to use curl to post xml to another php script (hosted @ tropo). The tropo-hosted script is then supposed to use the xml to place a phone call. In the below example, the tropo debugger is receiving the correct information, since messages like this show up in the debugger:

customerName:Kent is added into the context of app instance : ApplicationInstance[http://hosting.tropo.com/107029/www/ExternalPhoneHelper.php , sas_2-14-sm25ogjh4vlab5tropo]

Here's the curl php script that sends the xml data to tropo:

$token = "mytoken";//removed actual token
$url = PhoneHelper::$TROPO_URL;
$xml = "
    <session>
        <token>" . $token . "</token>
        <var name=\"action\" value=\"create\"/>
        <var name=\"customerName\" value=\"Kent\" />
        <var name=\"numberToDial\" value=\"##########\" />
        <var name=\"msg\" value=\"XML Test\" />
     </session>";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
echo curl_error($ch);
echo $output;
curl_close($ch);

The receiving script is empty:

 <?php

 ?>

If the call() and say() methods should be used, how would I reference the posted xml to get numberToDial and msg?

Here is the debugger log:

It looks like there are a few points of confusion/issues here, so I am going to try my best to tackle them all for you. The first thing I wanted to discuss is that the XML post to the session API is totally optional, it is just one way that you can submit your 'token request' to start an outbound call. If you are having issues getting this to work, let's just skip it and try a 'plane jane' HTTP GET straight from the browser until you are most comfortable:

api.tropo.com/1.0/sessions?action=create&token=123456&customerName=Kent&numberToDial=4075551212&msg=XML%20Test

Now on to the script itself, I found your accountID (yep, I work at Voxeo Labs / Tropo :P ), and I noticed a few things. First off you misspelled the application startURL, I am almost certain you meant ExternalPhoneHelper.php, but you typed ExterMalPhoneHelper.php, so you need to fix this first. Now the second thing, your file is actually blank, with the exception of the PHP tags.

So if you want to make a call and say something you can use call(); with a say(); or you can just use the combo/shortcut message(); method within your Tropo script:

<?php
 message("Received office voice mail.", array("to" => "+14075550100"));
?>

Now on to the last question, How do you get your posted data in the Tropo application context? Well, the good news is that this is DEAD simple, we actually scope these as globals in your application, so the numberToDial query string parameter becomes $numberToDial, for example:

<?php
 message($msg, array("to" => "+".$numberToDial));
?>

I really hope this helps, and if you still find yourself running into trouble hit up our support team, or find us in IRC on freenode (#tropo). My handle is dyer, and I am often in the channel lurking ;)

Take care!

  • That was the solution I needed. I didn't realize that the XML vars were scoped as globals! all I had to do was this: Thanks for the help! – objectivesea Jan 03 '12 at 03:34
