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
