The sound output setting system for information processing terminals is provided, capable of outputting a desired call progress tone from a terminal to be heard by the user easily with simple configuration. The system includes a SIP server and information processing terminals connected via a LAN using SIP. The SIP server has a tone management table for defining and recording types of sounds output by the information processing terminals in association with their identification codes, and an audio file storage region for recording audio files corresponding to the identification codes. The information processing terminal has a client application unit, which acquires a management table from the tone management table and an audio file from the audio file storage region at a predetermined time, and compares them with recorded data in its own tone management table region and audio file storage region to update the recorded data.
