摘要： IP network communication device which allows facsimile communication conforming to ITU-T recommendation V.34 in the network conforming to ITU-T recommendation T.38. This IP network communication device comprises a call controller for setting the call connection of a voice channel with another communication device, a voice controller which generates packets from voice data and facsimile data, sends the packets to the other communication device, and restores voice data or facsimile data from the packets received from the other communication device, and a digital signal processor which mediates the communication of voice data and facsimile data between an accommodated terminal and the voice controller. The digital signal processor turns ON the facsimile tone detecting function, echo canceling function, and fluctuation absorption buffer function if voice data is communicated, and turns these functions OFF if facsimile data is communicated.
