   * routing logic in an embedded language should allow reloading at runtime without kamailio restart
+=== Implementation Ideas ===
+Example kamailio.cfg for native interpreter:
+<code>
+# core parameters
+...
+# load modules
+...
+# modules parameters
+...
+routing="native" # default
+request_route {
+  ...
+}
+...
+reply_route {
+  ...
+}
+...
+</code>
+Example kamailio.cfg for lua interpreter:
+<code>
+# core parameters
+...
+# load modules
+...
+# modules parameters
+...
+routing="lua" with "/path/to/script.lua"
+</code>
+The script /path/to/script.lua:
+<code>
+function request_route()
+  ...
+  sr.t_on_branch("my_branch_route");
+end
+function reply_route()
+  ...
+end
+function my_branch_route()
+  ...
+end
+...
+</code>
+Expected changes:
+  * each module that offers an interpreter for config will advertise a special structure with functions to be executed on various events (e.g., request received, reply received, etc...)
+  * keep the name of routing blocks for failure/branch/branch-failure processing inside tm (along with existing index of the routing block for "native" config case)
+  * define the function names for routing blocks that are executed automatically
+    * such as:
+      * request_route
+      * reply_route
+      * onsend_route
+      * various event_route blocks (e.g., htable:init)
+    * eventually there can be a mapping of names used inside kamailio native config and functions inside the embedded interpreter that is inside each module, so each can have a naming pattern more suitable/friendly for its language (e.g., one may prefer request_route(), other requestRoute() and another RequestRoute())
+    * for event routes executed automatically (not the one armed for tm branch failure which sets the name at runtime), the pattern can be:
+      * modname_event_route(eventname) -- for example:
+<code>
+// event_route[htable:init]
+function htable_event_route(evname)
+  if evname=="init" then
+     ...
+  else
+     ...
+  end
+</code>
