A remark for kamailio transaction states point of view: in failure route
the entire transaction is in failed state, so there is not active
branch, so at that point it should delete all (previous) rtpengine
sessions/branches.
Re-routing to a new destinations should go via a branch route where a
new session is initiated in the rtpengine.
As I got it, the use of via-branch flag for deleting a session makes
sense in event route for branch-failure, when other branches can still
be active or one was answered.
Btw, a few questions for further clarifications: if a call has parallel
forking and rtpengine offer is executed for each branch, one is
answered, but the other branch-sessions are not not deleted, what does
rtpengine? It times them out, or keeps them for the duration of the call?
Also in the case of parallel forking, if via-branch is not give to
rtpengine offer command, does the 2nd (and the next) rtpengine offer
command overwrite the previous one, so the rtpengine keeps only the data
from the last one?
Cheers,
Daniel

I would think it does, as long as you supply the via-branch parameter.
Hi,
our scenario is the following: We have two clients registered
to our
Kamailio server, one with a TLS capable phone,
one via
websocket. Now,
when a call comes in, the call is forked and is
sent out to both
clients. rtpengine handling is done in the branch route, so
there are
two offers, and we use the "via-branch"
parameter.
Now, when one branch answers the call, what happens to the other
branch? I there a way to delete the other branch? How and in which
route? Or does Kamailio do this automatically?
You do it the same way as you handle an answer: You issue a
delete with
the via-branch option.
Doesn't this happen automatically when one uses rtpengine_manage() in
the failure_route?
