If this value is set to a non zero value, DTMF tones will be able to be sent out the phone lines when
the application starts a DTMF tone. The 8kHz DTMF tone information is taken from the internal DTMF
generator and digitally mixed with phone line transmitted RTP media. Note that this parameter allows
the media engine to configure itself to support this capability. The application can at any time determine
if DTMF tones get played out any individual phone line when the DTMF tone is started using the
StartDtmfTone(Int32, UInt32, VoipMediaEngine..::.DTMF_TONE, UInt32, Boolean, Boolean, Boolean) API procedure.
