The zero based ID of the multimedia audio input device the telephony engine will use for audio record operations. The device ID specified here is the same device ID as reported by the Windows multimedia APIs.

You can use the following telephony API procedures to interrogate your system in order to see what multimedia hardware is installed:

GetNumDigitalAudioInputDevices()()()
GetDigitalAudioInputDevice(Int32, VoipMediaEngine..::.LS_WAVEINCAPS)

If you specify the value of SIP_USE_PREFERED_AUDIO_DEVICE for this parameter, the telephony engine will use the preferred audio input device as specified by your system's multimedia settings.

If you specify the value of SIP_AUDIO_DEVICE_NOT_USED for this parameter, the telephony engine will disable its internal audio device support and will not manage audio input devices on the system.
