deviceInfo resource type

Namespace: microsoft.graph.callRecords

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Represents information about a device (microphone, speaker, camera, etc.) used in a call.

Properties

Property	Type	Description
captureDeviceDriver	String	Name of the capture device driver used by the media endpoint.
captureDeviceName	String	Name of the capture device used by the media endpoint.
captureNotFunctioningEventRatio	Double	Fraction of the call that the media endpoint detected the capture device was not working properly.
cpuInsufficentEventRatio	Double	Fraction of the call that the media endpoint detected the CPU resources available were insufficient and caused poor quality of the audio sent and received.
deviceClippingEventRatio	Double	Fraction of the call that the media endpoint detected clipping in the captured audio that caused poor quality of the audio being sent.
deviceGlitchEventRatio	Double	Fraction of the call that the media endpoint detected glitches or gaps in the audio played or captured that caused poor quality of the audio being sent or received.
howlingEventCount	Int32	Number of times during the call that the media endpoint detected howling or screeching audio.
initialSignalLevelRootMeanSquare	Double	The root mean square (RMS) of the incoming signal of up to the first 30 seconds of the call.
lowSpeechLevelEventRatio	Double	Fraction of the call that the media endpoint detected low speech level that caused poor quality of the audio being sent.
lowSpeechToNoiseEventRatio	Double	Fraction of the call that the media endpoint detected low speech to noise level that caused poor quality of the audio being sent.
micGlitchRate	Double	Glitches per 5 minute interval for the media endpoint's microphone.
receivedNoiseLevel	Int32	Average energy level of received audio for audio classified as mono noise or left channel of stereo noise by the media endpoint.
receivedSignalLevel	Int32	Average energy level of received audio for audio classified as mono speech, or left channel of stereo speech by the media endpoint.
renderDeviceDriver	String	Name of the render device driver used by the media endpoint.
renderDeviceName	String	Name of the render device used by the media endpoint.
renderMuteEventRatio	Double	Fraction of the call that media endpoint detected device render is muted.
renderNotFunctioningEventRatio	Double	Fraction of the call that the media endpoint detected the render device was not working properly.
renderZeroVolumeEventRatio	Double	Fraction of the call that media endpoint detected device render volume is set to 0.
sentNoiseLevel	Int32	Average energy level of sent audio for audio classified as mono noise or left channel of stereo noise by the media endpoint.
sentSignalLevel	Int32	Average energy level of sent audio for audio classified as mono speech, or left channel of stereo speech by the media endpoint.
speakerGlitchRate	Double	Glitches per 5 minute internal for the media endpoint's loudspeaker.
