      I have to admit you lost me somewhere on the way with what you
      want to do. But focusing on your final question "But when the uac

      registered?", the answer is

      <div dir="ltr">Hi,<br>
        <br>
        I followed pretty much the available tutorials for
        mid_registrar, but I can't figure out something:<br>
        <br>
        I have:<br>
        <br>
        loadmodule "registrar.so"<br>
        modparam("registrar", "attr_avp", "$avp(avp_json)")<br>
        modparam("registrar", "max_contacts", 1)<br>
        modparam("registrar", "tcp_persistent_flag",
        "TCP_PERSIST_DURATION")<br>
         <br>
        loadmodule "mid_registrar.so"<br>
        modparam("mid_registrar", "attr_avp", "$avp(avp_json)")<br>
        modparam("mid_registrar", "max_contacts", 1)<br>
        modparam("mid_registrar", "mode", 0)<br>
        modparam("mid_registrar", "tcp_persistent_flag",
        "TCP_PERSIST_REGISTRATIONS")<br>
        <br>
        and then:<br>
        <br>
          if (is_method("REGISTER")) {<br>
            $json(x) := "{}";<br>
        <br>
            python_exec("fn_lookup_account", "$rd|$socket_in(proto)");<br>
        <br>
            $avp(avp_json) = $json_compact(x);<br>
            mid_registrar_save("location");<br>
            switch ($retcode) {<br>
              case 1:<br>
                $du = $json(x/remote_dest);<br>
                $ru = $json(x/remote_uri);<br>
                route(relay);<br>
                break;<br>
              case 2:<br>
                xlog("L_INFO", "Absorb REGISTER!\n");<br>
                break;<br>
              default:<br>
                xlog("L_INFO", "Failed to save registration!\n");<br>
                break;<br>
            }<br>
        <br>
            exit;<br>
          }    <br>
        <br>
        <br>
        I do this because I want to store some configuration in the attr
        column that I don't want to retrieve every call.<br>
        <br>
        However, the mid_registrar example then continues with
        mid_registrar_lookup, and that works fine for calls originating
        from the main registrar going to the uac.<br>
        But when the uac starts a call, how do I validate the uac was
        previously registered?<br>
        <br>
        I tried with this below, but lookup doesn't work in this
        scenario.<br>
        <br>
        if (mid_registrar_lookup("location")) {<br>
          $json(x) := $avp(avp_json);<br>
          xlog("L_INFO", "$C(cs)$cfg_<a>file:$cfg_line$C(xx)</a> [$rm] Found
        mid_registrar_lookup from $si:$sp to $ru\n");<br>
        } else if (lookup("location")) {<br>
          $json(x) := $avp(avp_json);<br>
          xlog("L_INFO", "$C(cs)$cfg_<a>file:$cfg_line$C(xx)</a> [$rm] Found
        lookup from $si:$sp to $ru\n");<br>
        } else {<br>
          t_reply(404, "Not Found");<br>
          exit;<br>
        } <br>
        <br>
        <br>
        Thanks</div>
