 The sub-route blocks allow to make the configuration file modular, simplifying the logic and helping to avoid duplication of actions.
+==== branch_route ====
+Request's branch routing block. It contains a set of actions to be taken for each branch of a SIP request. It is executed only by TM module after it was armed via t_on_branch("branch_route_index").
+Example of usage:
+<code c>
+    request_route {
+        lookup("location");
+        t_on_branch("OUT");
+        if(!t_relay()) {
+            sl_send_reply("500", "relaying failed");
+        }
+    }
+    branch_route[OUT] {
+        if(uri=~"10\.10\.10\.10") {
+            # discard branches that go to 10.10.10.10
+            drop();
+        }
+    }
