Abstract
A feature telephone phone set has a call length recording and call sorting system which can record a plurality of called numbers, date, time, length and so on of each telephone call, and store records into two separate memory areas according to whether the call is a local call or a toll call. Recorded contents can be retrieved and shown on an LCD display. When the memory is full, older records are deleted automatically or manually. Because toll calls are more important than local calls, when the memory is full different criteria of deletion are obeyed when automatic deletion is performed. Special service codes and their descriptions are also provided, and each code can be retrieved by a common key and dialled by another common key.
