>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.
