Re: [SR-Users] TR: Failure Mode

Hello,

the new trace shows a serial forking, with the first branch timing out, but the second branch is getting a 183 response, and that's all. It is not the same scenario you described. I need the full trace, from initial invite to the final response sent back to caller to see what is the winning response code.

Cheers, Daniel

Hello,

Yes I’m sure the second branch is launched from Branch Failure Route.

If you check the timer trace, you can see the second is send 4 seconds later than the first ( I set the tm_inv to 4 seconds )

But in the trace I sent you the “last” invite. The kamailio sent 4 invites.

I will send you the complete trace

Hello,

looking at the trace, the routing is parallel forking, because the two branches are sent out at the same time, it is no final response to the first branch before the second is sent out.

Are you sure you sent out the second branch from failure route? From the sip trace is doesn't seem so.

Can you get a ngrep trace captured on kamailio server for such
situation?

Also, can you paste the failure_route block here along with the
log messages from the syslog?

Cheers,
Daniel

    I think serial because the new branch is only created in case
    the first is timeout.

    Hello,

    are you doing parallel forking or serial forking?

    Cheers,
    Daniel

        Hello,



        Some help here is needed



        # auto-discard branches from previous serial forking leg

        modparam("tm", "failure_reply_mode", 3)



        I test a call with two branches.



        1^st branch received a 408 timeout error

        2nd branch received a 486 busy.



        Normally the failure route should be with the 486.



        NOTICE: <script>: Failure route -----2---1--408----



        We can see the 408 is the winning reply but I understood
        from the documentation that if

        Failure reply mode is “3” , the winning reply is always
        the reply from the last branch J



        It’s a problem because if  the 1^st is timeout (because
        down), the second is OK but callee is busy ; we don’t send
        the right reply to the caller
