When an incomming call is lost, 1471 dialled from the incoming call does not reveal the number. This indicates that the call was not successful at the exchange. If the caller is hearing the ringing tone then it looks like a mis-routed call.

If you keep trying to call this number from a mobile and it does not ring, during the call try calling 1471 from the home number. If this connects to 1471 it proves it is a routing fault. If it connects to the incoming call (unlikely) then it could be a wiring fault.
