        Maybe you should look into GRUU stuff ;).<br>
        <br>
        On the TCP error - even if you set the TCP persistence flag, the
        UAC may close the TCP conn -&gt; you end up in the same
        situation. What you can do is to prevent OpenSIPS to open TCP
        conns when routing to end-users - the idea is to have end-users
        connecting to OpenSIPS and not the other way around. See

            <div>Hi Bogdan,<br>
            </div>
            So I thought of doing this and I have another problem. Say
            if a device registered from IP 1.2.3.4, and then moved out
            to different network and re-registered from IP 4.3.2.1,
            there is a stale registration lying in opensips for the same
            device from 1.2.3.4.<br>
          </div>
          Now when I use TCP as transport, opensips waits till connect
          timed out on unreachable IPs before sending the call to
          registered contact and the following messages are logged in
          syslog:<br>
          ERROR:core:tcp_blocking_connect: timeout 10 s elapsed from 10
          s<br>
           ERROR:core:tcpconn_connect: tcp_blocking_connect failed<br>
           ERROR:core:tcp_send: connect failed<br>
           ERROR:tm:msg_send: tcp_send failed<br>
          <br>
        </div>
        <div>Looks like opensips tries to do a TCP connect first with
          all registered contacts before actually routing the call.<br>
        </div>
        <div>I do,<br>
          modparam(&quot;registrar&quot;, &quot;tcp_persistent_flag&quot;, &quot;TCP_PERSISTENT&quot;)<br>
          <br>
          if(is_method(&quot;REGISTER&quot;)) {<br>
          setflag(TCP_PERSISTENT);<br>
                  setbflag(30);<br>
                  if(!save(&quot;location&quot;, &quot;fc1&quot;)) {<br>
                          t_reply(&quot;500&quot;, &quot;Error while saving AOR&quot;);<br>

                              <div>Hi,<br>
                              </div>
                              I am trying to solve a problem of having
                              one registration per AOR per device. So
                              user 1234 can register from device A,
                              device B and device C. But the user 1234
                              should not have multiple contacts from
                              device A alone. <br>
                            </div>
                            At times when the device loses network,
                            proxy doesn&#39;t receive de-register and the
                            contact stays in opensips till its expiry
                            time. So the same device is thus capable of
                            creating multiple contacts. I could solve
                            this by using &quot;fc1&quot; flag while doing a
                            save(&quot;location&quot;) but I need multiple
                            registrations to be allowed from different
                            devices !!<br>
                          </div>
                          So is there a way where while doing a
                          save(&quot;location&quot;), I set some sort of device id
                          along with it such that I identify and
                          overwrite the existing contact only if the
                          registration comes from same device-id or else
                          add it up for parallel forking.<br>
                        </div>
                        Do let me know if I make sense here and there&#39;s
                        a solution to this. Thanks for any suggestions
                        and directions.<br>
                        <br>
                        Thanks,<br>
