Recording of forwarded phone calls possible?

[James]

Is it possible to record phone calls that have been forwarded?

Let's say I provision an 800 number with a call-to number to X. I want to record the conversations for up to a few weeks in case their is a dispute about the contents of the call.

Is that possible with VXML and Plum's system? I can't seem to figure it out.

Thanks much,

James

Hi,

Yes, it is possible to record IVR calls that have been "bridge transferred" to another number. Here is some sample IVR code to demonstrate how this works:

callrecording.php

Code: Select all

<?php
header("Content-type: text/xml");
echo("<?xml version=\"1.0\"?>\n");
?>

<vxml version="2.0">
<form>
    <property name="recordcall" value="true"/>
    <field name="targetnumber" type="digits">
      <prompt>
        What phone number would you like to dial?
      </prompt>
    </field>
    <transfer destexpr="targetnumber">
      <prompt>
        Transferring to
        <say-as type="acronym">
          <value expr="targetnumber"/>
        </say-as>.
      </prompt>
    </transfer>
    <block>
      <disconnect/>
    </block>
</form>
<catch event="connection.disconnect">
  <submit next="savecallrecording.php" namelist="callrecording" method="post"/>
</catch>
</vxml>

savecallrecording.php

Code: Select all

<?php
echo "<?xml version=\"1.0\" encoding=\"latin-1\"?>";
?>
<vxml version="2.0">
    <form>
        <block>
<?php
	if (isset($_FILES['callrecording']) && is_uploaded_file($_FILES['callrecording']['tmp_name'])) {
		move_uploaded_file($_FILES['callrecording']['tmp_name'],"temp.ul");
		$timestamp = time();
		$cmdline = `/usr/local/bin/sox -t ul -r 8000 temp.ul $timestamp.wav`;
		unlink("temp.ul");
		echo "<exit/>\n";
	} else {
		echo "<exit/>\n";
	}
?>
        </block>
    </form>
</vxml>

Hope this helps.

Thanks very much, but I'm not getting the recorded call.

I get the call transferred, but the there is no object posted.

Is there something I'm doing wrong, or is this feature not enabled with the test account?

Thanks much,

James

Hi James,

We noticed from your IVR code that you are not using the IVR property, recordcall, which is what allows you to record a transferred phone call. You must have this line of IVR code

Code: Select all

<property name="recordcall" value="true"/>

in there to allow you to do this.

Many thanks!

If you want to kickout a converted file from the default VXML recording using Windows, this string will work. Just download Sox for Windows from sourceforge. To make MP3's you need to install a codec.

Code: Select all

sox -S -c 1 -b 8 -t ul -r 8000 infile.wav outfile.wav
