Abstract: If any of the communication terminals has incoming calls, calling signals are repeatedly output to the communication terminal at predetermined intervals until the communication terminal answers. When one communication terminal is called before another communication terminal answers its preceding call, calling signals to each communication terminal are repeatedly output alternately. Thus, a simple structure that is capable of changing output destinations for very calling signal output is provided. Upon receiving multiple incoming calls at about the same time, the apparatus can repeatedly output calling signals to corresponding communication terminals, without having multiple calling signal output apparatuses.

Abstract: An Internet communication control apparatus and its transmission control method is provided, to which communication terminals such as facsimile apparatuses and/or telephones are connected, that is connected to the Internet to perform transmission/reception with other communication terminals. When an off-hook state of a connected communication terminal is detected upon transmitting, a setting for dial tone signal reception is prepared, and the received signals are converted to a destination number. By checking the corresponding table, the destination number is converted into a destination address, and according to the content of the table, whether the communication is for facsimile transmission or telephone call is determined. According to the result of the determination, a facsimile process or telephone process is selectively performed so that the transmission operation does not seem abnormal and complicated.
