Patent ID: 7062033

Claim:
A DTMF data generating apparatus which is used in a communication system code-compressing and transmitting a voice signal to an opposite-side communication apparatus and which generates DTMF data for reporting a DTMF signal being intermingled with said voice signal to said opposite-side communication apparatus, said DTMF data generating apparatus comprising: a DTMF code information generating unit for detecting the DTMF code of a DTMF signal to be reported to said opposite-side communication apparatus and generating DTMF code information on the basis of the result of detection, a duration time information generating unit for detecting the output duration time of said DTMF signal to be reported to said opposite-side communication apparatus and generating duration time information on the basis of the result of detection, and a DTMF data generating unit for generating DTMF data including the destination information of said opposite-side communication apparatus, said DTMF code information generated by said DTMF code information generating unit and said duration time information generated by said duration time information generating unit.
