Packet communication system

A voice communication apparatus, comprising:

• a packet processor coupled to a packet communication network, said packet processor converting a voice signal from/to a packet data bilaterally to enable communication of the packet data to said packet communication network;
• a telephone controller coupled to a telephone network to enable communication of the voice signal on said telephone network;
• a switch connected with a voice input and output unit and which connects said packet processor or said telephone controller with said voice input and output unit;
• and
• a controller connected with said switch,
• wherein said packet processor receives the packet data transmitted from a transmission source coupled to said packet communication network, thereafter said telephone controller receives a signal transmitted from a transmission source coupled to said telephone network, and said signal transmitted from a transmission source coupled to said telephone network is rejected.

• a telephone controller coupled to a telephone network to enable communication of the voice signal on said telephone network;
• a switch connected with a voice input and output unit and which connects said packet processor or said telephone controller with said voice input and output unit;
• and
• a controller connected with said switch,
• wherein said packet processor receives the packet data transmitted via said packet communication network, thereafter said telephone controller receives a signal transmitted via said telephone network, and said telephone controller produces a busy tone signal to be transmitted to said telephone network.
