Hello,
we have a problem of final reply code in case of 302 and then 486 busy.
This is our scenario:
A, B and C are subscribers.
A ----------> Kamailio ----------> B Kamailio <---302---- B Kamailio -----------------------> C Kamailio <---486----------------- C A <---302---- Kamailio
Expected behavior: Kamailio should reply to A with 486, as C was busy, and not 302.
We have kamailio v5.1.4
In the call to B we set both failure and branch_failure: t_on_failure("failure_route"); t_on_branch_failure("failure_redirect");
in order to handle the 302 redirect per branch with: event_route[tm:branch-failure:failure_redirect] { if($T_reply_code == 301 || $T_reply_code == 302) { do redirect ... } }
and the final failure with: failure_route[FAILURE_ROUTE_LOCAL] { do something ... }
Since we have 'modparam("tm", "failure_reply_mode", 3)' my expectation is to get the winning reply from the branch of last step.
Is there any configuration I'm missing? Since we manage the redirect with a branch-failure, is the winning reply calculated in a different way?
Thanks Marco
