A system and method for managing calls provides a user with a telephone ring which was previously designated in the system. The system includes a ring memory unit for storing ring data for the user, a ring-providing unit for loading the ring data designated by the user from the memory unit, and a line interface for providing the loaded ring data to a telephone of the user when the user receives a call, either from an external network or a local network such as an internal extension within a PBX system. The system is advantageous because it provides system participants with their own custom-selected rings, which prevents confusion in a multiple-user setting.
