    <tt>Hi Pete,<br>
      <br>
      Looking to the logs, I see only one line :<br>
      <br>
      Apr 21 09:58:56 dev01 /usr/local/opensips_2.2/sbin/opensips[4766]:
      DBG:uac_registrant:reg_tm_cback: tm [0x7f2ceb70b2f0] notification
      cb for FAKED_REPLY [408] reply at [1492761536]<br>
      <br>
      The "r</tt><tt><tt>eg_tm_cback" is the TM callback used to report
        back to the uac_registrant module the reply code for the sent
        REGISTER. And I see there a 408 timeout :-/ .....<br>
        <br>
        Even more, the "run_reg_tm_cback" function (that triggers the
        build of the auth hdr) does not show up logging anything (and
        there are some debug over there).<br>
        <br>
        So, are you sure that the 401 is actually received ? maybe the
        second REGISTER is actually a retransmission of the first one ?<br>
        <br>
      </tt>Best regards,<br>

                    <div>Hello,<br>
                      <br>
                    </div>
                    I am trying to use the uac_registrant module (2.2)
                    to register via TCP but when it recieves the 401 it
                    is not adding the Authorization header.<br>
                    <br>
                  </div>
                  It does work with UDP so I get:<br>
                  <br>
                </div>
                REGISTER -> 401 (with WWW-Authenticate) ->
                REGISTER (with Authorization) -> 200 OK<br>
                <br>
              </div>
              However when I tell it to use TCP it doesn't add the
              Authorization header:<br>
              <br>
              UPDATE registrant SET forced_socket = 'tcp:<a
                moz-do-not-send="true" href="http://1.2.3.4:5060"
                target="_blank">1.2.3.4:5060</a>';<br>
              <br>
            </div>
            REGISTER -> 401 (with WWW-Authenticate) -> REGISTER
            (no Authorization) -> 403 Forbidden<br>
            <br>
          </div>
          <div>I've included the debug log for the failing TCP REGSITER
            attempt: <a moz-do-not-send="true"
