title: pjsip iOS handling ip change during call
body: <p>I want to handle ip change form wifi to 4g and back during an ongoing call using pjsip on ios.<br>
  I have followed all the steps form pjsip website: <a href="https://trac.pjsip.org/repos/wiki/IPAddressChange" rel="nofollow">https://trac.pjsip.org/repos/wiki/IPAddressChange</a> and here I have found that the call is disconnected after the <code>pjsua_acc_set_registration(the_acc_id, PJ_FALSE);</code> is sent. 
  Also I don't figure it out how to send the re registration at point 4.</p>
  
  <blockquote>
    <p>"And finally, once unregistration in 2b) above is complete,
    re-register (with TCP)."</p>
  </blockquote>
  
  <p>Any advice, suggestion, link to any resource that will hell me solve the issue is well come.</p>
