You are identifying performance management requirements for a VoIP migration. What three key performance indicators would you use to track media quality? (Choose three.)

One-way delay (latency) affects conversational quality; ITU-T G.114 recommends keeping end-to-end delay below 150 ms, and exceeding this threshold noticeably degrades the user experience.

Trunk group usage measures capacity and utilization of trunks, which is a capacity-planning metric rather than a real-time media quality indicator.

Jitter is the variation in packet arrival times and directly degrades voice quality by causing gaps or distortion if the jitter buffer cannot absorb the variation.

Packet loss causes clipping and dropped syllables; even small percentages above 1-2% noticeably reduce MOS scores and render calls difficult to understand.

Call detail records capture accounting data such as call duration and endpoints, not real-time measurements of the RTP media stream quality.

Call processing performance counters track signaling and call-setup metrics, not the media stream quality experienced by end users.

Echo is an impairment addressed by echo cancellation hardware/configuration, not a standard real-time flow KPI tracked as part of media quality monitoring.

Crosstalk is a physical-layer signal interference issue on analog circuits, not a measurable IP network performance indicator for VoIP deployments.
