Fields

  NameDescription
AverageNoiseMagDb
This is the power of the average noise signal at the time of detection. It is specified in dB (Decibels). The 0dB power level is referenced to full scale sin(x) 16 bit PCM.
DtmfTone
Represents the DTMF tone that was detected. For supported DTMF tones, see the VoipMediaEngine..::.DTMF_TONE enumeration.
Freq1MagDb
This is the power of the lower DTMF frequency signal at the time of detection. It is specified in dB (Decibels). The 0dB power level is referenced to full scale sin(x) 16 bit PCM.
Freq2MagDb
This is the power of the higher DTMF frequency signal at the time of detection. It is specified in dB (Decibels). The 0dB power level is referenced to full scale sin(x) 16 bit PCM.
StateOn
Indicates whether the DTMF digit has transitioned to the "ON" state or the "OFF" state.
