A method and apparatus for controlling ring volume if a telephone by memorizing the ring volume in state where a telephone call is answered responsive to ring tone of the telephone and then, generating the ring tone with the memorized ring volume when a next telephone call occurs. The ring volume of a telephone is controlled by a user setting an initial volume value in memory and a central processing unit determines whether a ring detector detects a first ring signal after setting the initial volume value, produces a current volume value for controlling a volume of a ringer according to the initial volume value upon detection of the first ring signal, produces a reduced volume value by reducing the current volume value by a predetermined step when the telephone is answered after the first ring signal, replaces the initial volume value stored in the memory with the reduced volume value, produces an increased volume value by increasing the current volume value by the predetermined step upon detection of a subsequent ring signal for step increasing the volume of the ringer and repeating the step of producing an increased volume value until the telephone is answered, and replaces the initial volume value stored in memory with the increased volume value when the telephone rings more than one time before being answered.
