A telephone ring controller includes a database associating all or part of received call related information to any one of an available plurality of audible ring types. In the disclosed embodiments, a call related information/ring type association table is maintained associating area codes, exchange numbers, household names, and/or entire telephone numbers to a particular ring type. Alternatively or additionally, ring types may be associated with digits of an incoming telephone number. When a match is determined as between received call related information and a pre-stored entry in the call related information/ring type association table, a particular ring is output by a ringer capable of at least two different types of rings. If no match is found, the telephone system operates otherwise in a conventional fashion, i.e., a default ring signal is output by the ringer. The entries in the call related information/ring type association table may be input manually using a keypad at the telephone system. Alternatively, received call related information with respect to a current (or past) incoming telephone call can be stored as an entry in the call related information/ ring type association table and associated with a particular audible ring.
