[OpenSIPS-Users] sip message enters on bucle

Hi Bogdan,

        
Ok, now we known that is happening. But, is it logic? or is it a bug in 1.6.4.2 version?


           Curiously this does not happen with UDP signaling.

        

        Thanks.

        Regards.

    Jorge,

    

    the message is not looping, it is retransmitting - it is something
    different. OpenSIPS tries to open a new TCP conn to the destination
    (as there is no existing one), but it fails in timeout as you cannot
    open a TCP conn somewhere behind a NAT.

    

    Regards,

    Bogdan

        Hi Bogdan,

        

        Is correct, Z.Z.Z.Z:5062 is a public adress behind a NAT. I have
        found that opensips haven't this tcp connection, now this
        account has changed the public adress.

        

        But the sip messages keeps in the loop. It's like if Opensips is
        looking for a tcp connection that it hasn't.... ?¿

        

        Thanks.

        Regards.

          Hi Jorge,

          

          So opensips tries to send the BYE to Z.Z.Z.Z:5062 via TCP
          (guess based on Route hdrs), but nobody is listening on TCP -
          is this address pointing behind a NAT ? why is not accepting a
          new TCP connection.

          

          On the other side, what you can do is to reduce the timeout on
          TCP connection, so opensips will react sooner:

          Regards,

              Hi Bogdan,

              

              Exactly, is ready, OpenSIPS try to reach to destination
              but now the account 2105 haven't the location: 
              Z.Z.Z.Z:5062

              

              In fact, when OpenSIPS try to reach to there, it write in
              log:     (this account uses TLS signaling)

                Hi Jorge,

                

                It looks like Asterisk generates the BYEs and
                retransmits it because there is no reply coming back
                from opensips. Normally the BYE is end 2 end replied (so
                the other end device should generate the reply for BYE).

                But looking at the 477 reply you get from OpenSIPS, I
                suspect that OpenSIPS was trying to forward the BYE
                request (maybe via TCP), got blocked and failed at the
                end - this failure resulted in the 477 reply.

                

                Check the opensips logs to see error when processing the
                BYE.

                

                Regards,

                Bogdan

                   Hi,

                    

                    I have the follow VoIP platform;  OpenSIPS
                    1.6.4.2-tls + Mediaproxy 2.0 + a pair of Asterisks
                    1.4 (behind SER)

                    

                    It works fine but sometimes a sip message enters on
                    a loop. Asterisk sends 5 sip
                        messages at every
                        turn
