From config processing point of view, there is only one
branch set for
going out to the target domain.
If the dns query returns more than one address, that's not due to config
operations adding the branches, thus branch route is not executed.
Logically, it is a single target, it is supposed to be the "same" system
from kamailio routing point of view.
Obviously, it is open source and one can code new feature and add an
option to execute config routing blocks on various cases, including on
dns-based re-routing. But as it was designed in the past, branch_route
is executed only on branches resulted from config processing, not from
dns query.
As you could notice, in the branch route the r-uri has the domain in its
value, the dns is done later, when about to send to the network.
But then, there is onsend_route executed after dns is done, but there is
no option to change the message anymore.
Cheers,
Daniel

Thanks for reply but its not possible to set
branch_route in
failover_route for dns failover.
the branch is sent before the failure_route.
i will keep reparse_on_dns_failover to 1 that solves partially .
