BlindTransfer command

The BlindTransfer command is used to connect two phones together. If the connection is established, the phone which connected the phones together will leave the conversation.

Command example usage:

It is used when a line disconnects between a client and a member of the support staff. Then a CallChanged notification is sent and the client is blind transfered to another suppert staff member.

Parameters:

Parameter name Value Description Mandatory
CallId string value,
e.g. H2Wwb		 The call ID of the call you want to run the BlindTransfer command on. By default it is known from the CallChanged notification. No
TransferorParty string value
(caller or callee)		 The party member who will make the transfer. Yes
Target int value,
e.g. 1001		 The phone number you want to transfer the party member to. Yes
FinishedUrl string value,
http://yourdomain.com/process.php		 The ID, the caller, the callee and the duration of the call are sent to this URL. No

OzML simple example:

The callee is transferred to 1001. 

<?xml version="1.0"?>
<Response>
  <BlindTransfer TransferorParty="callee" Target="1001"></BlindTransfer>
</Response>

Detailed example:

1st it plays hello.wav from ContentStorage/Static directory in Ozeki Phone System install directory to all participants of the phone call.
Then says to all participants: "The callee will be transfered to number 1001."
Then it transfers the callee to 1001.

<?xml version="1.0"?>
<Response>
  <Play Party="all">hello.wav</Play>
  <Speak Party="all">The callee will be transfered to number 1001.</Speak>
  <BlindTransfer TransferorParty="callee" Target="1001" FinishedUrl="http://domain.com/proc.php">
  </BlindTransfer>
</Response>

You can see an example solution for processing the FinishedUrl parameter below. When the BlindTransfer is completed, this php file will be called. The application will log the details of the calls into a simple file, and send back an OzML response. 

<?php
	$receiveTime = date("c");
    $outString = "BlindTransfer Completed: ID = " .$_REQUEST['Id'].
                 ",Caller=" .$_REQUEST['Caller'].
                 ",Callee=" .$_REQUEST['Callee'].
                 ",Duration=" .$_REQUEST['Duration'].
                 ",Date=$receiveTime\r\n";
                
    file_put_contents('BlindTransferLog.txt', $outString , FILE_APPEND);
    
    print "<Response>";
        print "<Speak>Thank you for your call!</Speak>";
    print "</Response>";
?>

BlindTransfer command is used in OzML responses to this notification:

CallChanged, RecordCompleted
