Hi Søren,

Thanks to all your support and info I found the problem. The fix is now 
available on GIT repo on all maintained versions.

Please update and confirm.

Hi Søren,

It seems that the callee route set is stored in db (see the 
b2b_entities table, the route1 field 
="<sip:XX.XX.XX.120;lr;ftag=a9ff31f61f2601c916f6044c2e20e16a-3c47;did=895.92039fc>")

Can you run the b2be_list MI command before and after the restart, to 
see if indeed, the callee route set is not properly restored ?

    Hi Søren,

    In the scenario with the restart, after the restart, the
    sequential requests generated by b2b is missing the Route header -
    and it is bypassing the proxy - can you ppst the DB records for
    b2b you have during the restart?

        Sure. I’ve attached the two files.

         (B2B server)

         (OpenSIPS Proxy)

         (SIP Client)

        My scenario:

                    <server>

        <id>server1</id>

                    </server>

                    <client>

                 </bridge>

            <state>1</state>

             </init>

        </scenario>

        I’m doing this because my SIP provider can’t handle multi
        dialogs, so if I first send a call to the sip client and if
        the call is unanswered I can’t redirect the call to voicemail
        since this will generate a new to_tag. And this can’t my SIP
        provider not handle. So therefore I need some B2B logic to
        make this happen for me.

        Hi Søren,

        Do you have an ngrep capture (taken from opensips b2b,
        covering all calls/legs involved in the scenario) showing the
        call with the B2B restarted ?

            Only if I reload the B2B the BYEs is sent directly to the
            client. – But the funny thing is this only happens if the
            client is receives a call.  If the client initialize the
            call everything works fine.

            With or without restarting the B2B isn;t the BYE sent by
            client to the B2B instance ?

                Hello there,

                I’ve some strange issues with the B2B module. – I use
                MySQL as backend, and if I reload OpenSIPS the BYE is
                sent directly to the client, and not my SIP proxy. My
                B2B and OpenSIPS is two difference servers.

                If I take a look in b2b_entities table I notice the
                contact1 field contains the IP address of the client.
                 But if I don’t reload the OpenSIPS the BYE will be
                sent correctly the my proxy, and then to the client.

                Now, my question is how can I make sure that B2B
                server will not try to communicate with the clients
                after a reload?

                loadmodule "b2b_entities.so"
