<p><P>PROBLEM TO BE SOLVED: To provide a voice over Internet protocol (VoIP) communication device capable of communicating non-audio data in audio data real-time transport protocol (RTP) stream packet communication. <P>SOLUTION: A VoIP communication device according to the present invention prepares audio data RTP packets to be transmitted to a communication network by receiving or generating a stream of the audio data RTP packets, generates non-audio data RTP packets in a different data size from the prepared audio data RTP packets, replaces at least one of the prepared audio data RTP packets with the relevant non-audio data RTP packets, and transmits a stream of audio data RTP packets including the replacing non-audio data RTP packets to the relevant communication network. Furthermore, the VoIP communication device according to the present invention extracts the non-audio data RTP packets contained in the stream of audio data RTP packets received from the communication network based on the data size of the non-audio data RTP packets and reads information contained in the extracted non-audio data RTP packets. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
