Play audio message

Use this function to play an audio message previously loaded on the TVox system.

Ivr_play($val = array())

<?php

$audioFile = "audio_message";
$result = $this->Ivr_play(array($audioFile, 0));
if($result[0] == TVOX_IVR_CALLER_EXIT){
  $this->RightExitIVR();
}

?>

Make sure to replace audio_message with the message to played.

In the example on the right side we can see $result[0] == TVOX_IVR_CALLER_EXIT` that check if caller hangup the call and $this->RightExitIVR() close call statistics with correct values.

$val = array($audioFile, $canInterrupt)

Set call variable

Use this function to save value into call and popup variable

Ivr_setvar($val = array())

<?php

define("CUSTOMER_CODE", "CUSTOMER_CODE");
$this->Ivr_setvar(array(CUSTOMER_CODE, "value"));

?>

Make sure to replace value with the value to save.

$val = array($variableName, $variableValue)

}

?>
