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?

Hi Bogdan-Andrei,

Sure. I've attached the two files.
 (B2B server)
 (OpenSIPS Proxy)
 (SIP Client)

My scenario:

<?xml version="1.0"?>
<scenario id="StofaB2B" name="MS start and end" param="2" type="script">
     <init>
         <bridge>
            <server>
                <id>server1</id>
            </server>
            <client>
                <id>client1</id>
                <type>message</type>
                <destination>
                    <value type="param">1</value>
                </destination>
            </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 ?

Hi Bogdan-Andrei,

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.

Hi Søren,

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?

My topology:
ISP -> B2B -> Proxy -> Client

My config:

loadmodule "b2b_entities.so"
loadmodule "b2b_logic.so"
modparam("b2b_logic", "script_scenario", "/etc/opensips/b2b.xml")
modparam("b2b_entities", "db_url", "mysql://opensips:XXX@XX.XX.XX.XX/b2b"<mailto:mysql://opensips:XXX@XX.XX.XX.XX/b2b>)
modparam("b2b_entities", "db_mode", 1)
modparam("b2b_logic", "db_mode", 1)
modparam("b2b_logic", "db_url", "mysql://opensips:XXX@XX.XX.XX.XX/b2b"<mailto:mysql://opensips:XXX@XX.XX.XX.XX/b2b>)
modparam("b2b_entities", "replication_mode", 1)
modparam("b2b_logic", "init_callid_hdr", "Init-CallID")

if (is_method("INVITE") && !has_totag()) {
b2b_init_request("B2B","sip:$tU at XX.XX.XX.XX"<mailto:sip:$tU at XX.XX.XX.XX>);
exit;
}
