title: Asterisk change callerid after consultation call
body: <p>we use an Asterisk as telephone system and have the following issue:</p>
  
  <p>We have multiple phones and want to redirect a call after a consultation. </p>
  
  <p>We get a call from external number and Phone A answers the call. Than he makes a consultation call to Phone B. Phone B answers and talks with Phone A. In this moment the CallerID From Phone A is visible on the Display of Phone B. When Phone A hangs up the call with Phone B. The caller is connected now with Phone B. But on the Display of Phone B is not the CallerID from the external call, but the ID of Phone A. </p>
  
  <p>How I can change the CallerID on the Display of Phone B after Phone A hung up?</p>
  
  <p><strong>Update:</strong>
  A colleague find a solution, we add </p>
  
  <pre><code>sendrpid = pai
  </code></pre>
  
  <p>to the sip.conf in the general area. This solved this Problem.</p>
