These commands are used in responses to the Api Extension Control notifications coming from the phone system. If a client calls an api extension you can control it with these commands. These commands are written in OzML. To write an OzML command this is the standard form:
<command parameter="..."> 'parameter between the command nodes' </command>

An OzML response is always between <response> nodes:
<response> 'commands and parameter between the nodes' </response>

Example:

<Response>
  <Delay>1</Delay>
  <Speak>Congratulations, this is your first OzML Response command.</Speak>
  <Delay>2</Delay>
  <Speak>Have a nice day!</Speak>
</Response>
