Hi, to achieve the described behavior you could call t_on_branch(BRANCH_NAME) before calling t_relay. In this way each branch, after forking and before being relayed, will traverse the branch_route named BRANCH_NAME.
http://www.kamailio.org/docs/modules/devel/modules/tm.html#tm.f.t_on_branch Hope this helps.
