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.

Cheers,
Daniel

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.

 

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