    <p>I am not familiar with the IMS extensions, if nobody else comes
      with other suggestions, I recommend to set debug=3 in your
      kamailio configuration file and then look at the syslog, there
      should be a lot of DEBUG messages that may give more hints about
      what happens.</p>
    <p>Also, when sending Kamailio logs, do not make screen shots, just
      copy and paste them, it is easier to read as well as search in the
      source code for them by copy&paste.</p>
    <p>Cheers,<br>
