FIELD: electronic communication engineering. SUBSTANCE: telephone communication system provides for direct transmission of speech information between remote parties of local telephone networks coupled through common-use computer networks. Transmitting section of system 1 has telephone set 1, local telephone line 2, signal detector-distributor 3, tone set recognizing device 4 for determination of called party number, device 5 transmitting the recognized number in the form of standard protocol of computer communication, analog-to-digital converter 6, compressor 7, computer 8 connected to computer network 9. Receiving section 1 of system has telephone set 10, local telephone line 11, converter 12 of called number information, call signal telephone dial, device 14 of sequence of speech and tone signal transmission, computer 15 connected to computer network 9, decompressor 16, digital-to-analog converter 17 and speech signal transmitter 18. EFFECT: higher efficiency. 1 dwgt
