An Internet telephony gateway system includes a main controlling device that prepares a packet comprising compressed voice data and transmits the packet to the communication network, or extracts compressed voice data from the packet received from the communication network and transmits the extracted data to at least one specific function board in response to a signal form of the extracted data. The system also includes at least one specific function device connected to the main controlling device for processing one of analog signal protocol and digital signal protocol. The extracted data is provided to a digital specific function device to communicate with a communication device capable of processing digital data, and the extracted data is provided to an analog specific function device to communicate with a communication device capable of processing analog data.
