摘要 |
<p>Voice is input to a voice input and output portion (11). Thereafter, a digital-analog portion (12) converts analog signal of voice into digital data. An RTP port confirming portion (13) confirms whether or not a communication according to the RTP port can be made. When the communication according to the RTP port cannot be made, with reference to a history table (14), a port through which a voice data communication can be made is determined. Digitized voice is sent to a call controlling portion (15). The call controlling portion (15) performs a call control for the voice communication. When the communication according to the RTP port can be made, the voice data is sent to an IP communication portion (16). The IP communication portion (16) paketizes the voice data. Packetized voice data according to the IP is sent to a LAN interface portion (17). The LAN interface portion (17) outputs the packetized voice data to a network.</p> |
