PURPOSE: An Internet phone call system having a hands-free set is provided to output a sound signal of a computer by selecting one of an external apparatus and a microphone-earphone, according to user selection, so as to output a telephone conversation through various apparatuses. The Internet phone call system is provided to remotely supply the sound signal of the computer to a microphone-earphone, so as to perform a hands-free function to implement a service distance-free function. CONSTITUTION: A computer(10) comprises as follows. A computer controller(11) processes data transmitted through an Internet network. A data processor(12) converts sound data supplied from the computer controller(11) into an audible sound through a speaker to output the audible sound, and converts the sound data into a sound signal supplied from a microphone of a microphone-earphone(40) to make the sound signal data. An interface(13) outputs the data or the sound signal. A memory(14) stores the data and a program necessary for Internet calls. A base box(20) comprises as follows. The first light emitting element(21-1) makes a user visually recognize the sound signal. The second light emitting element(21-2) makes the user visually recognize the remotely-transmitted sound signal. A touch switch(22) performs a switching operation, to transmit the sound signal to an external apparatus or a sound signal transceiver(30). The sound signal transceiver(30) receives the remotely-transmitted sound signal, and transmits the sound signal to the microphone-earphone(40) by a cable.
