title: With Asterisk, how to make a call between 2 externals then hangup?
body: <p>My problem is the following.</p>
  
  <p>I want:</p>
  
  <ul>
  <li>to be called by A</li>
  <li>read a code from A (ex. <em>15334#</em>)</li>
  <li>retrieve the phone number of B from a database with the code readed from A</li>
  <li>call B</li>
  <li>once A is in communication with B, hangup after 3 seconds</li>
  </ul>
  
  <p>For now, it works, <strong>BUT when I hangup (after 3 seconds), communication between A and B is closed</strong>.</p>
  
  <p>A and B are external numbers.</p>
  
  <p><strong>How to hangup server without closing communication between A &amp; B?</strong></p>
  
  <p>Thanks a lot,</p>
