Flight numbers / callsigns

Hi, Does anyone know of a resource (printed or online) that replaces the now defunct Flight Routings book (see here), which allows the decoding of flight callsigns including the ever increasing number of alphanumeric callsigns into the corresponding published flight number, airports of origin and destination, types, days of operation and so on?

Thanks in advance

Graeme
