After I add route(DISPATCH) to branch_route branch calls are going throught asterisk

# Manage outgoing branches

branch_route[MANAGE_BRANCH] {

        xdbg("new branch [$T_branch_idx] to $ru\n");

        xnotice("BRANCH: $rm $ru [$ci]");

        route(DISPATCH);

        route(NATMANAGE);

}

but if I set

    $ru = "sip:34200@domain.org";

first main ($ru) INVITE resolve to contact of ip phone INVITE sip:34200@172.16.3.7:5060

but branch doesnt' resolve INVITE sip:34201@domain.org

Is there any way to resolve it?
