Example

<?xml version="1.0"?>
<vxml version="2.0">
  <form>
    <block>
      <prompt bargein="false">
        You have to wait until the end of this sentence
        before you'll be able to interrupt the audio with DTMF.
      </prompt>
    </block>
    <field name="myfield">
      <grammar type="application/x-jsgf">
        ( 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | "#" | "*" )+
      </grammar>
      <prompt bargein="true">
        Now you can press any DTMF button and the prompt will
        be interrupted.
      </prompt>
      <filled>
        You entered <value expr="myfield"/>
      </filled>
    </field>
  </form>
</vxml>
