+Testing
+
+A basic test of this contribution
+Once compiled and installed, a basic test of this contributed software
+involves calling the new exported function in the routing script of the
+OpenSIPS configuration file:
+
+  # dial '1234*256' from a UAC first
+  isn_query();
+  t_relay();
+
+According to the freenum.org cookbook, the ISN '1234*256' is being
+provided for testing. After dialing the caller hears monkeys screaming.
