How many branches do you have? Failure route is called for the whole
transaction failure and not for every individual failed branch.

Hello everyone,
I wanted to ask those who know if Kamailio's behavior I'm facing is
expected or I should make some improvements to the configuration.
Kamailio version is 5.1.0.
I have a route where RTPEngine parameters are being collected and
/rtpengine_offer()/ is called. After that
/t_on_reply("REPLY_SIP_TO_SIP");/ followed by the
/t_on_failure("FAILURE_SIP_TO_SIP");/ are used. The idea is to process
all responces except 415 or 488 from UAC as usual in
/onreply_route[REPLY_SIP_TO_SIP]/ and use
/failure_route[FAILURE_SIP_TO_SIP]/ to update SDP with
/rtpengine_offer()/ if necessary.
/onreply_route[REPLY_SIP_TO_SIP]/ just goes to /exit;/ if /$rs/ equals
415 or 488. This works fine with Htek phone which sends 100, 180 and
then 488. But I can not see
/failure_route[FAILURE_SIP_TO_SIP]/ execution for calls to Zoiper
which replies with 100 and immediately 415.
t_on_failure(failure_route) documentation says: "Sets failure routing
block, to which control is passed after a transaction completed with a
negative result but before sending a final reply." and to be honest I
don't really understand how lacking of responce prevents failure_route
from executing.
Thanks a lot!
