This object reports the Media Delivery Index Delay Factor for the stream, in milliseconds, which measures the burstiness of packet arrivals relative to the stream's expected bit rate. Administrators use it to detect jitter or buffering issues affecting real-time media quality, since a high delay factor indicates packets are arriving in bursts rather than smoothly. For example, a delay factor climbing from a few milliseconds to several tens of milliseconds on a voice stream would point to increasing network jitter degrading call quality.
