    <p>Hi Daniel,</p>
    I have read the warning, so I changed kamailio.cfg.customtt.tt2 and
    did <b>not</b> make a tags_header.customtt.tt2. This time with the
    $ct variable.<br>
    As [%logreq -%] is expanded to R=$ru ID=$ci UA='$ua' I added the <u>new</u>
    CT=$ct with escaped quotes and ; as terminator as specified:<br>
    <br>
    <tt>[% argv.service='proxy'; PROCESS
      '/etc/ngcp-config/templates/etc/kamailio/tags_header.tt2' -%]</tt><tt><br>
    </tt><tt>[% # Add here your customizations to parameters evaluated
      in file kamailio/tags_header.tt2 -%]</tt><tt><br>
    </tt><tt>logreq="R=$ru ID=$ci <b>CT=$ct</b> UA=\'$ua\'";</tt><tt><br>
    </tt><tt><br>
    </tt><tt>#!KAMAILIO</tt><br>
    <br>
    So I think exactly as specified, but no result, as the first log in
    the generated auth.cfg still is             <br>
    <tt>xlog("L_NOTICE", "Extracted caller info from PAI,
      subscriber=$var(realm_user)@$var(realm_domain) - </tt><tt><b>R=$ru
        ID=$ci UA='$ua'</b></tt><tt>\n");</tt><tt><br>
    </tt><br>
    I can also change constants.yml, or will this be overwritten by an
    upgrade?<br>
    <br>
    Regards,<br>
    <br>
    Henk<br>

      <tt>Hi,<br>
        have you read the ATTENTION warning at the beginning of
        tags_header.tt2 ?<br>
        You can find there how to change it.<br>
        <br>
        Also, please DO NOT change the IP= , but rather ADD a new

        <p>Hi Daniel,</p>
        <p>It looks I have to overwrite logreq from tag_header.tt2, but
          if I add the following line in kamailio.cfg.tt2 and build the
          configuration it does not have any effect:<br>
        </p>
        <p>logreq="R=$ru ID=$ci IP=$ct UA=\'$ua\'";<br>
        </p>
        Any advise on what to change exactly?<br>
        <br>

          <tt>Hi Henk,<br>
            you can either block the call by User Agent or you can print
            out the Contact header in the log, if you want.<br>
            You can use the "$ct" variable in the kamailio.cfg<br>
