Example 1: using val

<IVR>
  <Set var="amount" val="1234"/>
  <Speak voice="en-US-Standard-C">Hello, you have {{amount}} dollars in your account.</Speak>
</IVR>

Since in the above XML there is nothing else to be done, if notification of CallStatus=completed is enabled, you will receive a request containing this: Direction=inbound&To=05011112222From=090111122226&CallerName=09011112222&DomainName=brs.basix.ne.jp&CallUUID=c58ae32a-6f19-47ba-a402-6f3d031cb1ab&CallStatus=completed&var_amount=1234

Example 2: using expr

<IVR>
  <GetJSON var="user" url="https://somewhere.com/get_user?phone={{CallingNumber}}"/>
  <Set var="discount" expr="user.balance * 0.2"/>
  <Speak voice="en-US-Standard-C">Your discount will be {{discount}} dollars</Speak>
</IVR>
