This Integer32 object, measured in milliseconds, reports the end-to-end average transmission delay for voice packets on a bearer connection. High latency on a voice call causes noticeable conversational lag, talk-over, and echo problems for the people on the call. An engineer responding to a complaint about delayed voice on a specific connection would check this value against acceptable voice latency thresholds (typically well under 150ms) to confirm the network path is the culprit.
