I have vxml script for IOS with transfer element:

<form id="transfer_to_reception">

<transfer name="mycall" destexpr="'phone://400'" connecttimeout="60s" cisco-longpound ="true" bridge="true">
  <filled>
   <log> TRANSFERTORECEPTION :: Transfer to reception 400 </log>
   <assign name="mydur" expr="mycall$.duration"/>
   <if cond = "mycall == 'busy'">
    <log> TRANSFER ITEM :: Destination is busy</log>
    <prompt bargein="true">
     <audio src="4v01.wav"></audio>
    </prompt>

   <elseif cond = "mycall == 'noanswer'"/>
    <log> TRANSFER ITEM :: called party is not answering </log>

   <elseif cond = "mycall == 'near_end_disconnect'"/>
    <log> TRANSFER ITEM :: Calling party disconnected </log>

   <elseif cond = "mycall == 'far_end_disconnect'"/>
    <log> TRANSFER ITEM :: Called party disconnected </log>

   <elseif cond = "mycall == 'unknown'"/>
