To get the branch attributes, the code should be similar to execution of

the code in t_reply.c for branch failure handling already looks very
similar to failure handling. run_failure_handlers() use branch
on_failure = t->uac[picked_branch].on_failure;
whereas run_branch_failure_handlers() use branch
on_branch_failure = t->uac[picked_branch].on_branch_failure;
then both create faked request environment, run the route handler, and
restore the original environment.
why the faked request in case of branch failure does not include correct
$ru goes beyond my knowledge of tm module.
indeed, looking at the code, the failure-route and branch-failure events
are using only the request in the uas side of the transaction. It will
require writing some c code to get the attributes from uac structure.
Most of them are stored there (uri, branch flags, path, ...) but some
are not (dst_uri) ...
Cheers,
Daniel
