A terminal apparatus 1A includes a network interface 11 that is connected to a communication network for transmitting data packets including voice packets containing voice data; a converter for converting voice signals into voice packets and vice versa; a speaker 24 for outputting the voice signals; a storage unit 13 for storing volume values each corresponding to a plurality of different operation modes; a detection unit for detecting the operation mode; and a control unit 12 that reads the volume value corresponding to the detected operation mode from the storage unit and controls a signal level of the voice signal output from the speaker 24 based upon the read volume value. The terminal is typically connected to an IP network via a LAN interface and communicates via Voice over IP (VoIP). The operating modes may relate to a speakerphone mode (utilizing the terminal apparatus' internal speaker 24 and microphone 25), a headset mode (utilizing an external headset 26) and an incoming call reception mode.
