    I am trying to send the following command to wireless phones:
     
    <CiscoIPPhoneExecute>
         <ExecuteItem Priority='0' URL='Play:chime.raw' />
    </CiscoIPPhoneExecute>
     
    The wireless phones we have are the 7921 and the 7925.
     
    The command above works very well on the 7960, which is on the same network and same TFTP server.
