[OpenSIPS-Users] Need to understand the seral forking logic of opensips .

[Sasmita Panda]

Hi ,

I know this is a very basic question . Still I need some clarification .

I have 2 contact for same number , When I place a call Openips give that to
1st if 1st contact reject the call with 486 busy , then opensips try the
same call to the 2nd contact without rejecting the call .

In the next call for same number , opensips tries to 2nd contact if that
rejects the call with 486 it wont try to the 1st contact again . Why is
this happening ?

route{

                        if (!serialize_branches(1)){
                                sl_send_reply("500","Unable to load
contacts");
                                exit;
                        }else{
                                if (next_branches()){
                                        t_on_failure("1");
                                }
                        }
}

failure_route[1] {

   if ( t_check_status("404|477|480|481|408|486|50[234]")){
         if (next_branches())
         {
                t_on_failure("1");
                route(1);
         }

    }
}

This is in my config file . i have gone through the doc
https://www.opensips.org/Documentation/Script-CoreFunctions-1-11#toc44
but not able to understand properly .

How can I print the internally stored branches on avp ?
